AB  - Alfalfa (Medicago sativa L.) hosts several species of aphid, Acyrthosiphon pisum (Harris), Aphis craccivora Koch and Therioaphis trifolii (Monell). The preference of the aphids of alfalfa plants for dense assemblies or individual plants, as well as for healthy or infested plants, was investigated in the field as in the laboratory. Years of field research have revealed the specific preferences of all three species of aphid. A. pisum and T. trifolii are most commonly found in alfalfa crops, while A. craccivora is mostly found on alfalfa weeds. Also, a single species of aphid alone is usually present on a plant. In order to determine the reason for this clear preference and to establish whether at the very beginning, i.e. at the stage of choosing a host, aphid species distance themselves from each other, we tested the effect of the volatiles of healthy and infested plants on their attractiveness to aphids. A. craccivora is repelled by the volatiles of dense crops and plants previously infested with one of the other two species. A. pisum and T. trifolii choose a dense assembly of plants, repelled by the volatiles of plants previously infested with A. craccivora. A. pisum displays the weakest competitive traits, and A. craccivora the strongest. This research showed that competition between aphid species does not occur only when they find themselves on the same plant at the same time, fighting for resources, but also in the choice of plant, in order to avoid later competition. © 2023 The Author(s).

AB  - Plant viruses, and aphids as their vectors, are limiting factors in sugar beet production. Viral plant diseases are currently impossible to treat, but knowing the flight patterns of aphids can help reduce the number of potential virus vectors. Monitoring of aphid flight activities in sugar beet fields was done using yellow water traps from April to the end of November. During the two years of investigation, a total of 5 514 specimens from 75 different taxa were collected. All localities recorded the highest number of individuals at the end of May/beginning of June. This is the period when sugar beet develops intensively, so the risk of virus infection is the highest. The most numerous species were Aphis fabae Scopoli, Aphis spiraecola Patch., Phyllaphis fagi (L.), Myzus persicae (Sulzer), Rhopalosiphum padi (L.), Sitobion avenae (Fabr.), Acyrthosiphon pisum (Haris) and Therioaphis trifolii (Monell). The most important vectors are A. fabae, A. spi-raecola and M. persicae. Aphis fabae is a species that feeds on sugar beet and causes significant damage by feeding and its vector activity. Myzus persicae was the most abundant in autumn, A. spiraecola was present throughout the whole flight-monitoring period. Among the caught aphids, twelve species alien to Europe were collected. © 2023, Czech Academy of Agricultural Sciences. All rights reserved.

AB  - Populations of the most abundant alfalfa aphids, Acyrthosiphon pisum and Therioaphis trifolii, have periodic fluctuations, and many factors affect their dynamics. In the present study, we examined the impact of daily air temperatures on the abundance of two alfalfa aphids in field conditions. The numbers of these two aphids on alfalfa were documented at two locations in a representative alfalfa growing area in Serbia during a three-year field study. Based on the records of aphid abundance and daily air temperatures during the whole study, it was found that a correlation between the sum of optimal daily air temperatures for aphid development, the sum of maximum daily air temperatures and the number of recorded aphid peaks was significant and can therefore be considered for the detection of suitable temperature conditions to increase aphid abundance. The study shows that the highest correlations were between a high density of A. pisum and the sum of optimal daily air temperatures for its development (Ck=0.569) and between a high density of T. trifolii and the sum of maximum daily air temperatures (Ck=0.595). The length of time required for the growth of populations of the two alfalfa aphids differed: 30 days for A. pisum and 5 days for T. trifolii. The association of temperature data to alfalfa aphid abundance enables a projection of their population behavior in changed future climate conditions. This study suggests increased population sizes of T. trifolii and decreased population sizes of A. pisum on alfalfa under the warmer conditions that are expected to prevail in the future. © 2022 Journal of Agricultural Sciences (Belgrade).

AB  - Progeny numbers and life parameters of Tribolium castaneum reared on a range of different animal feeds which varied in their protein-carbohydrate ratios (corn starch; corn feed flour; wheat bran; soybean meal; corn gluten; soy protein concentrate and soy protein isolate), four initial (population) densities (1, 2, 5 and 10 insect pairs) were evaluated. Adult insects were kept for seven days on a range of different diets to feed and oviposit before they were removed. After removing the adults, the emerging progeny were examined. The study found T. castaneum offspring could not develop on a carbohydrate-rich diet (corn starch) and on protein-rich diets (corn gluten, soy protein concentrate and soy protein isolate). Soy isolate showed a high, possibly insecticidal effect on parents. The fastest total development (egg to adult) (23.25–23.88 days, depending on the initial density), the highest offspring number (111.63–324.13) and the highest offspring body mass (1.38–1.73 mg) were recorded in wheat bran, while the slowest egg to adult development (35.13–37.88 days), the lowest offspring number (25–29) and the lowest offspring mass (1.04–1.48 mg) were recorded in soybean meal. The higher initial densities caused the eclosion period to be prolonged, reductions in female productivity and in offspring body mass on all diets. Initial density interacted differently with diet type in terms of offspring number, so as the density rose, the number of offspring in wheat bran and corn feed flour increased, while in soybean meal it remained low at all initial densities. This research gives us a better insight into the development of T. castaneum in animal feed that can help us to improve existing pest management in a way of finding a better solution to store products based on their susceptibility to this storage pest.

AB  - The effects of brewer's yeast and wheat patent flour on Tribolium castaneum (Herbst) life parameters at different population densities (1, 2, 5 and 10 pairs) were examined. A standard diet (95% wheat flour + 5% brewer's yeast) was used as control. The effect was examined on the duration of egg, larval and pupal stages, total development cycle, first adult emergence, eclosion period, the total number of offspring, number of offspring per female and body weight of adult offspring. For each diet type and population density, adults were allowed to feed and oviposit for 7 days before removal from diets. A longer larval stage was recorded in brewer's yeast (between 23.88 and 26.25 days, depending on population density) and patent flour (17.63–23 days) compared to the standard diet (12.88 and 13.38 days). The longest eclosion period was recorded in patent flour (19–21.23 days), which was the only diet unaffected by population density. In the brewer's yeast and standard diet, the period of eclosion was prolonged with the increase in population density. The lowest number of progeny was recorded in patent flour (44.29–49.63 insects), followed by brewer's yeast (22.86–177 insects), while the highest number of progeny (107.25–313.38 insects) was recorded in the standard diet. Population density did not affect the total number of progeny in patent flour, which remained low at all densities, while in the brewer's yeast and standard diet the rise in population densities caused a rise in progeny numbers. The type of diet did not affect the body weight of adult progeny: the highest body mass of progeny was recorded at the lowest population density and the lowest mass at the highest. This study provides insight into poorly researched development cycle and reproductive strategies of T. castaneum on brewer's yeast and patent flour, which are important stored products.

AB  - Movement of the red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), in stored products is mediated by food volatiles and other semiochemicals. RESULTS: In two-way olfactometer assays, T. castaneum was more attracted to wheat bran previously infested with conspecifics than to uninfested bran. Chemical analysis showed that 1-pentadecene was present in the headspace of T. castaneum-infested wheat bran, but not detectable in the headspace of uninfested bran. An olfactometer was used to test the effect on T. castaneum behaviour of 1-pentadecene, and of volatiles from wheat bran with and without 1-pentadecene. The lowest concentration of 1-pentadecene exhibited an attractive effect, compared to the control (n-hexane). Slightly higher concentrations showed a neutral effect, while the highest concentrations repelled T. castaneum. Wheat bran with a low 1-pentadecene concentration was more attractive than wheat bran alone, whereas higher concentrations of 1-pentadecene were repellent. CONCLUSION: The results provide important information on intraspecific, semiochemical-mediated behaviour in T. castaneum, which could potentially be used to develop new methods to monitor the flour beetles in stored products.

Chemical analysis showed that 1-pentadecene was present in the headspace of T. castaneum-infested wheat bran, but not detectable in the headspace of uninfested bran. An olfactometer was used to test the effect on T. castaneum behaviour of 1-pentadecene, and of volatiles from wheat bran with and without 1-pentadecene. The lowest concentration of 1-pentadecene exhibited an attractive effect, compared to the control (n-hexane). Slightly higher concentrations showed a neutral effect, while the highest concentrations repelled T. castaneum. Wheat bran with a low 1-pentadecene concentration was more attractive than wheat bran alone, whereas higher concentrations of 1-pentadecene were repellent. CONCLUSION: The results provide important information on intraspecific, semiochemical-mediated behaviour in T. castaneum, which could potentially be used to develop new methods to monitor the flour beetles in stored products.",

AB  - Tribolium castaneumis one of the most economically important insects that damages stored products. The effects of several infested or uninfested raw feed materials (wheat bran, coarse wheat meal, corn feed flour), feed products (compound feed for pigs and for laying hens) and flour mixed with brewer's yeast on the food-searching behaviour ofT. castaneumadults were studied in a total of 48 combinations. Preference and olfactometer tests revealed that all the tested uninfested and intraspecific infested substrates were significantly more attractive toT. castaneumthan the control (represented by part of an arena or olfactometer arm without substrate). We determined that all infested substrates were 2-9 times more attractive than uninfested in the preference test, while in the olfactometer test, they were 3-8 times more attractive. In comparing the attractiveness of the infested and uninfested substrates, in both tests wheat bran was found to be the most attractive substrate toT. castaneumadults and coarse wheat meal the least. The results of the present study contribute to our knowledge of how raw feed materials and products influence the behaviour ofT. castaneumand their susceptibility to infestation, and indicate the possible utilization of wheat bran in monitoring processes ofT. castaneumin pest management programmes.

AB  - The bean weevil (Acanthoscelides obtectus, Say) is a serious pest of stored bean seeds. Bean weevil control relies heavily on the use of synthetic insecticides. In the search for a sustainable alternative, the residual contact toxicity and anti-oviposition activity of thyme (Thymus vulgaris L.), rosemary (Rosmarinus officinalis L.) and basil (Ocimum basilicum L.) essential oils as well as their dominant components (thymol, alpha-pinene, 1,8-cineole and linalool) were tested against A. obtectus adults. Out of the seven tested botanicals, T. vulgaris oil, thymol and linalool exhibited the highest toxic potential (>90% mortality). Females were less susceptible than males. The insecticidal activity of these botanicals was much greater when they were applied on glass compared to direct application to the bean. All tested botanicals reduced oviposition by bean weevil females. T. vulgaris oil, thymol and a-pinene also deterred bean weevil oviposition, as revealed by a two-choice test. Our research shows that T. vulgaris oil and thymol are promising and sustainable alternatives to synthetic pesticides for protecting stored beans against the bean weevil.

AB  - The fauna of aphids appearing on cucurbits, including oilseed pumpkin have been poorly investigated in Serbia. Yellow water traps were used to determine the diversity of aphid species visiting cucurbits in Serbia and to monitor their flight activity. During the years 2009 to 2011, a total of 1,447 specimens were collected and a total of 57 different aphid taxa were identified. In 2009, the highest total number of aphids were caught (755), followed by 203 and 489 aphids in 2010 and 2011, respectively. The most abundant species were Aphis fabae (15%), Myizus persicae (13.4%) and Acyrthosiphonpisum (11.7%), followed by Anoecia corni (6.4%) and Aphis gossypii (5.6%). All of them, except A. corni, are reported as efficient vectors of cucurbit viruses. These five species represent 52.1% of all aphid species collected within this study. Out of 57 taxa found in oilseed pumpkin crops, 17 are known as vectors of ZYMV, 18 of WMV and 15 of CMV. Generally, 25 out of a total of 57 taxa are known as vectors of at least one of three viruses present in Serbia. From total of 1,447 specimens collected during three years of investigation, 917 (63.4%) are vectors of at least one of three viruses. Individual oilseed pumpkin plants were frequently colonized by A. gossypii during all three years of investigation. Results of this study showed that Serbian oilseed pumpkin growing localities are grouped among medium to reach in aphidofauna, according to total Shannon-Weaver index values which varied from 1.8 to 2.8. The highest value of Shannon-Weaver (2.8) was recorded in the Bački Petrovac I locality in 2009, while the lowest Shannon-Weaver (1.8) was recorded in Kisač locality in 2010. The maximum values of Shannon-Weaver diversity index in almost all crops were recorded in the second week of investigation or in early stages of oilseed pumpkin growth when plants had 5-6 true leaves or were in flowering stage, when potential virus infection could lead to significant yield losses.
AB  - Afidofauna koja se javlja na tikvama, uključujući uljanu tikvu do sada nije dobro ispitana u Srbiji. Da bi utvrdili diverzitet lisnih vaši koje posećuju useve tikava u Srbiji, kao i da bi pratili aktivnost i dinamiku njihovog leta, koristili smo žute lovne klopke. Tokom perioda od 2009. do 2011. godine ukupno je sakupljeno 1447 jedinki i determinisano 57 taksona lisnih vaši. Tokom 2009. godine, uhvaćen je najveći broj jedinki (755), dok je tokom 2010. i 2011. godine uhvaćeno 203, odnosno 489 jedinki lisnih vaši. Najzastupljenije vrste bile su Aphis fabae (15%), Myzus persicae (13,4%) i Acyrthosiphon pisum (11,7%), a zatim Anoecia corni (6,4%) i Aphis gossypii (5,6%). Za sve vrste, osim za A. corni, potvrđeno je da su vektori virusa tikava. Ovih pet najzastupljenijih vrsta predstavljaju 52,1% od svih sakupljenih jedinki vaši u toku ovih istraživanja. Od ukupno 57 taksona nađenih u usevima uljane tikve, 17 su poznati vektori ZYMV, 18 WMV i 15 CMV. Ukupno posmatrano, 25 od 57 nađenih taksona su vektori bar jednog od tri virusa tikava prisutnih u Srbiji. Od ukupno 1447 jedinki sakupljenih tokom tri godine istraživanja, 917 (63,4%) su vektori bar jednog od tri virusa tikava. Kolonizacija pojedinačnih biljaka uljane tikve vrstom A. gossypii uočavana je često tokom sve tri godine istraživanja. Rezultati ovih istraživanja, na osnovu ukupnog Shannon-Weaver-ovog indeksa diverziteta koji je varirao između 1,8 i 2,8, ukazuju da se lokaliteti na kojima se gaji uljana tikva u Srbiji svrstavaju u red srednje bogatih do bogatih po sastavu i brojnosti afidofaune. Najveća vrednost Shannon-Weaver-ovog indeksa diverziteta (2,8) zabeležena je tokom 2009. godine na lokalitetu Bački Petrovac I, dok je najniži indeks diverziteta (1,8) zabeležen na lokalitetu Kisač tokom 2010. godine. Shanon-Weaver-ov indeks diverziteta u gotovo svim ispitivanim usevima dostigao je maksimalne vrednosti u drugoj nedelji istraživanja ili u ranim fazama razvoja uljane tikve kada biljke imaju 5-6 pravih listova ili su u fazi cvetanja, što predstavlja najosetljivije faze za ostvarenje infekcije virusima koje mogu da dovedu do značajnih gubitaka u prinosu.

In 2009, the highest total number of aphids were caught (755), followed by 203 and 489 aphids in 2010 and 2011, respectively. The most abundant species were Aphis fabae (15%), Myizus persicae (13.4%) and Acyrthosiphonpisum (11.7%), followed by Anoecia corni (6.4%) and Aphis gossypii (5.6%). All of them, except A. corni, are reported as efficient vectors of cucurbit viruses. These five species represent 52.1% of all aphid species collected within this study. Out of 57 taxa found in oilseed pumpkin crops, 17 are known as vectors of ZYMV, 18 of WMV and 15 of CMV. Generally, 25 out of a total of 57 taxa are known as vectors of at least one of three viruses present in Serbia. From total of 1,447 specimens collected during three years of investigation, 917 (63.4%) are vectors of at least one of three viruses. Individual oilseed pumpkin plants were frequently colonized by A. gossypii during all three years of investigation. Results of this study showed that Serbian oilseed pumpkin growing localities are grouped among medium to reach in aphidofauna, according to total Shannon-Weaver index values which varied from 1.8 to 2.8. The highest value of Shannon-Weaver (2.8) was recorded in the Bački Petrovac I locality in 2009, while the lowest Shannon-Weaver (1.8) was recorded in Kisač locality in 2010. The maximum values of Shannon-Weaver diversity index in almost all crops were recorded in the second week of investigation or in early stages of oilseed pumpkin growth when plants had 5-6 true leaves or were in flowering stage, when potential virus infection could lead to significant yield losses., Afidofauna koja se javlja na tikvama, uključujući uljanu tikvu do sada nije dobro ispitana u Srbiji. Da bi utvrdili diverzitet lisnih vaši koje posećuju useve tikava u Srbiji, kao i da bi pratili aktivnost i dinamiku njihovog leta, koristili smo žute lovne klopke. Tokom perioda od 2009. do 2011. godine ukupno je sakupljeno 1447 jedinki i determinisano 57 taksona lisnih vaši. Tokom 2009. godine, uhvaćen je najveći broj jedinki (755), dok je tokom 2010. i 2011. godine uhvaćeno 203, odnosno 489 jedinki lisnih vaši. Najzastupljenije vrste bile su Aphis fabae (15%), Myzus persicae (13,4%) i Acyrthosiphon pisum (11,7%), a zatim Anoecia corni (6,4%) i Aphis gossypii (5,6%). Za sve vrste, osim za A. corni, potvrđeno je da su vektori virusa tikava. Ovih pet najzastupljenijih vrsta predstavljaju 52,1% od svih sakupljenih jedinki vaši u toku ovih istraživanja. Od ukupno 57 taksona nađenih u usevima uljane tikve, 17 su poznati vektori ZYMV, 18 WMV i 15 CMV. Ukupno posmatrano, 25 od 57 nađenih taksona su vektori bar jednog od tri virusa tikava prisutnih u Srbiji. Od ukupno 1447 jedinki sakupljenih tokom tri godine istraživanja, 917 (63,4%) su vektori bar jednog od tri virusa tikava. Kolonizacija pojedinačnih biljaka uljane tikve vrstom A. gossypii uočavana je često tokom sve tri godine istraživanja. Rezultati ovih istraživanja, na osnovu ukupnog Shannon-Weaver-ovog indeksa diverziteta koji je varirao između 1,8 i 2,8, ukazuju da se lokaliteti na kojima se gaji uljana tikva u Srbiji svrstavaju u red srednje bogatih do bogatih po sastavu i brojnosti afidofaune. Najveća vrednost Shannon-Weaver-ovog indeksa diverziteta (2,8) zabeležena je tokom 2009. godine na lokalitetu Bački Petrovac I, dok je najniži indeks diverziteta (1,8) zabeležen na lokalitetu Kisač tokom 2010. godine. Shanon-Weaver-ov indeks diverziteta u gotovo svim ispitivanim usevima dostigao je maksimalne vrednosti u drugoj nedelji istraživanja ili u ranim fazama razvoja uljane tikve kada biljke imaju 5-6 pravih listova ili su u fazi cvetanja, što predstavlja najosetljivije faze za ostvarenje infekcije virusima koje mogu da dovedu do značajnih gubitaka u prinosu.",

AB  - Using a two-way olfactometer, the effects of the whole wheat grains and coarse wheat meal odors on the primary Sitophilus granarius (L.), S. oryzae (L.) and S. zeamais (Motch.) and secondary Tribolium castaneum (Herbst) and T. confusum (Du Val) stored-product pests behavior were examined. Whole wheat grains and coarse wheat meal were used in uninfested and infested form. Whole wheat grains were infested with S. oryzae adults and coarse wheat meal with T. castaneum adults. The odors of infested wheat grains depending on the insect species were 1.9 to 3 times more attractive than the uninfested wheat grains odors, except for the T. castaneum for whome the odors of infested and uninfested grains were equally attractive (p = 0.641). The greatest difference in the attractiveness of the infested and uninfested wheat grains odors was found for T. confusum (3 times longer in the arm with the odors of infested grain), and the smallest for S. granarius (1.9 times). We found that all primary and secondary stored-product pests, depending on the species, were 1.4 - 2.4 times more attracted to the odors of infested compared to the odors of uninfested wheat meal. The greatest difference in the atraction of infested and uninfested coarse wheat meal odors was recorded for the T. confusum, whose adults were 2.4 times longer in the arm with the odors of infested coarse wheat meal than in the arm with odors of uninfested wheat meal, while the smallest difference (1.4 times) was recorded for S. oryzae. The results of this study give a significant contribution to a better understanding of the storage insects behavior, which could be used in the design of new methods of monitoring of their presence in stored products.
AB  - Pomoću dvokrakog olfaktometra ispitivan je uticaj mirisa pšenice u zrnu i pšenične prekrupe na ponašanje primarnih štetočina Sitophilus granarius (L.), Sitophilus oryzae (L.) i Sitophilus zeamais (Motch) i sekundarnih štetočina Tribolium castaneum (Herbst) i Tribolium confusum (Du Val). Pšenica u zrnu i pšenična prekrupa korišćeni su u neinfestiranom i infestiranom obliku, s tim da su zrna pšenice bila infestirana adultima S.oryzae a prekrupa adultima T. castaneum. Miris infestirane pšenice u zrnu je bio u zavisnosti od insekatske vrste od 1,9 do 3,0 puta atraktivniji od mirisa neinfestirane pšenice, osim za adulte T. castaneum za koje je bio podjednako privlačan (p=0,641). Najveća razlika u atraktivnosti mirisa infestirane i neinfestirane pšenice je zabeležena kod T. confusum (3 puta više vremena u kraku sa mirisom infestiranog zrna), a najmanja kod S. granarius (1,9 puta). Sve primarne i sekundarne štetočine su u zavisnosti od vrste bile od 1,4 - 2,4 puta više privučene mirisom infestirane, nego mirisom neinfestirane pšenične prekrupe. Najveća razlika u atraktivnosti mirisa infestirane i neinfestirane prekrupe, utvrđena je kod T. confusum, čiji su adulti proveli 2,4 puta više vremena u kraku sa mirisom infestirane prekrupe nego u kraku sa mirisom neinfestirane, a najmanja razlika (1,4 puta) zabeležena je kod S.oryzae. Rezultati ovih istraživanja daju značajan doprinos boljem poznavanju ponašanja skladišnih insekata, što bi moglo da se upotrebi u osmišljavanju novog načina praćenja njihovog prisustva u uskladištenim proizvodima.

AB  - New alien species of aphids (Illinoia liriodendri (Monell), Wahlgreniella nervata (Gillete), Takecallis arundicolens (Clarke) and Tinocallis takachihoensis Higuchi) have been found for the first time in Serbia. These records are new for the Balkan Peninsula. Data of Ericaphis scammelli (Mason), species recently mentioned in Serbia, are also presented in the text. The species have been found during the last five years at four sites (Belgrade, Zemun, Mladenovac and Bojnik) on five cultivated plants. Ericaphis scammelli is a pest of blueberry and a vector of Blueberry scorch virus. The other four develop colonies on decorative plants: I. liriodendri has been found on Liriodendron tulipifera, W. nervata on Rosa sp., T. arundicolens on Pseudosasa japonica and T. takachihoensis on Ulmus x hollandica. The origin of three of the species (E. scammelli, I. liriodendri and W. nervata) is North America and two (T. arundicolens and T. takachihoensis) have come from East Asia. Their morphology, biology and the damage they inflict are discussed here, as well as their potential economic and environmental threat. Only parthenogenetic viviparous females of all 5 species have been collected. Their biology has not been studied enough in Europe and needs further examination. Original drawings of all species are presented.

AB  - The diet of entomophagous coccinellids is mainly based on aphids and other food sources such as pollen, nectar, or fungal spores. Knowledge of their foraging behavior on plants infected by powdery mildew and their survival on fungal spores is currently limited. In this study, we investigated the olfactory response of Coccinella septempunctata to odor emission of barley plants infected by powdery mildew and their survival on fungal spores in the presence or absence of aphids. Odors released by powdery-mildew infected plants were more attractive for ladybirds compared to those of uninfected controls. After 3days, the survival rate of ladybirds feeding only on powdery-mildew spores was less than 50%, while for ladybirds feeding exclusively on Rhopalosiphum padi aphids, the survival rate was close to 90%. After 15days, the highest survival rate (almost 80%) was observed for ladybirds feeding on plants with both aphids and powdery mildew. Molecular analyses confirmed the presence of fungal spores in ladybird guts when feeding either on powdery mildew or on a mixed diet. Our results provide new insights into foraging behavior of entomophagous coccinellids revealing the potential of powdery mildew to be utilized as important non-essential food in a mixed diet, but also its lethal effect if consumed alone.

AB  - Flight activity of aphids as potential vectors of viral infection of alfalfa plants were monitored in Serbia for the first time in Europe. Research was conducted at the location Progar (Srem) for two years using six yellow water traps. A total of 1626 individual winged aphids were collected. The collected specimens were classified into 49 different taxa. During the two-year study, maximum population density of aphids and maximum potential vector activity were noted at the beginning of June, during the second alfalfa intercut. More than 65% of the collected specimens were potential vectors of the most important alfalfa viruses, Alfalfa mosaic virus (AMV) and Cucumber mosaic virus (CMV). The most numerous winged aphid species on alfalfa were Aphis craccivora, Aphis fabae, Aphis gossypii, Aphis pomi/ spiraecola and Therioaphis trifolii. The Morisita-Horn similarity index was used to calculate similarities in species composition among the traps. High values of this index showed no significant differences among the aphids in traps. It indicates that one trap alone could provide good insight into the abundance, aphid diversity and number of potential vector species in small alfalfa fields.

AB  - The effects of population densities (10, 25, 50 and 100 adults/50 g) and three diet types (protein-rich, carbohydrates-rich and compound feed) on life parameters (first emergence, development rate, number of progeny and body weight) of T. castaneum progeny were assessed. For each diet type and population density unsexed adults were allowed to feed and oviposit for 7 days before removal. No progeny developed on protein-rich diets (sunflower meal, soybean concentrate, and corn gluten). In carbohydrates-rich diets (corn feed flour, wheat bran, coarse wheat) and compound feed for pigs and laying hens, first adults required the least time to emerge in wheat bran and control diet (wheat flour + 5% yeast) (15.2-16.5 days), and the longest in corn feed flour (23.1-24.5 days). In wheat bran and control diets, the adult emergence period was the shortest (15.7 and 15.2 days) at the initial population densities of 100 and 50 adults/50 g, and significantly longest (16.5 and 16 days) at the lowest density. Conversely, adults fed on feed for hens diet emerged the latest, after 22.5 days, at the population density of 100 adults/50 g, and the earliest, after 18.6 days, at 25 adults/50 g. The shortest period of adult emergence at all population densities was found in the control (15.9-20.2 days) and wheat bran (18 -29.7 days), and the longest in feed for hens (56.2 days) and pigs (59.5 days) at the highest population density. Considering all densities, number of progeny were the highest in control diet (498-1226 adults) and wheat bran (354-1344 adults), and lowest in coarse wheat (220-300 adults). With increasing population density, progeny body weight decreased, and the highest weight was found in control diet and wheat bran (1.7 and 1.6 mg) at the lowest population density, and the lowest weight (1.0 mg) in hen and pig feeds at the highest density.

AB  - Behavior bioassays were conducted in the laboratory (23 ± 1°C and 50 ± 5% r.h.) using the olfactometer to determine the effects of essential oils of three plant species in the Cymbopogon genus (Lemongrass), Cymbopogon nervatus, C. proximus and C. schoenanthus, on adults of Tribolium castaneum. The effect of essential oils was compared to a commercial biopesticide based on azadirachtin at three concentrations (0.0001, 0.001 and 0.01%). The results showed that all essential oils and the azadirachtin-based biopesticide had significant (p  lt 0.05) repellent effects on T. castaneum adults at all tested concentrations, except C. proximus essential oil which showed a neutral effect at the lowest concentration. The highest concentrations of the essential oils of C. nervatus and C. proximus had significantly stronger repellent effects (p  lt 0.05) than the lowest concentration. At the concentrations of 0.0001 and 0.001% all tested essential oils and azadirachtin showed a similar repellent effect without statistically significant difference, whereas the oil of C. nervatus had the highest repellent effect on adults of T. castaneum at the 0.01% concentration. Considering all tested variations, the essential oils of plants of the genus Cymbopogon showed similar or stronger repellent effects on T. castaneum adults than the biopesticide based on azadirachtin.
AB  - U laboratorijskim uslovima (24±1°C i 50±5% r.v.v.) je pomoću olfaktometra ispitivan uticaj etarskih ulja iz tri biljne vrste roda limunovih trava (Cymbopogon nervatus, Cymbopogon proximus i Cymbopogon schoenanthus) na ponašanje (atraktivnost/repelentnost) adulta T. castaneum. Uticaj etarskih ulja na ponašanje kestenjastog brašnara, poređen je sa uticajem biopesticida na bazi azadirahtina u tri koncentracije: 0.0001, 0.001 i 0.01%. Rezultati testiranja pokazali su da sva etarska ulja i biopesticid na bazi azadirahtina u svim ispitivanim koncentracijama ispoljavaju statistički značajan odbijajući uticaj - repelentni efekat na adulte kestenjastog brašnara, osim najniže koncentracije ulja iz biljke C. proximus koja je ispoljila neutralan efekat na brašnara. Najviša koncentracija ulja iz biljaka C. nervatus i C. proximus je ispoljila statistički značajno jači repelentni efekat u odnosu na najnižu koncentraciju. Sva ispitivana etarska ulja i azadirahtin su u koncentracijama 0.0001 i 0.001% ispoljila sličan repelentni efekat bez statistički značajne razlike, dok je ulje iz biljke C. nervatus u koncentraciji 0.01% prouzrokovalo statistički značajno jači repelentni efekat na adulte kestenjastog brašnara u odnosu na ostale ispitivane supstance. Na osnovu rezultata istraživanja sa adultima kestenjastog brašnara može se zaključiti da su etarska ulja iz tri vrste biljaka iz roda Cymbopogon ispoljila sličan i/ili jači repelentni efekat od biopesticida na bazi azadirahtina. Takođe, dobijeni rezultati pokazuju značajan potencijal upotrebe ulja ovih biljaka kao prirodnog sredstva za zaštitu uskladištenih biljnih proizvoda.

AB  - Population dynamics and flight activity of alfalfa aphids were documented at two locations in Serbia in 2011 and 2012. Additionally, the abundance of coccinellid predators was tested for correlation with aphid abundance. In order to verify the potential presence of the invasive Acyrthosiphon kondoi, aphids were collected from 44 alfalfa fields. Two sampling methods were used: stem samples and water traps. There were two seasonal peaks for aphids and coccinellids during both years, the end of May and the end of August. The most abundant aphid species was Therioaphis trifolii. Eight aphidophagous coccinellids were recorded. The invasive Harmonia axyridis (Pallas) was one of the three most abundant coccinellids. Pearson's product-moment correlation showed a significant correlation of coccinellid predators associated with aphids on alfalfa. Pearson's product-moment correlation between the number of aphids on alfalfa stem and in traps was found significant only for T trifolii, which was the most numerous species in the traps. More Aphis craccivora were collected with water traps as compared to alfalfa stems, whereas more Acyrthosiphon pisum specimens were collected from alfalfa stems than from traps. The invasive species A. kondoi was not recorded in Serbia during this study.

AB  - Aphids (Aphididae, Hemiptera) are efficient vectors of plant viruses and a significant problem in potato growing. Production of healthy seed potato is possible if the number of aphids is reduced, as well as their ability to come into contact with the plant and transfer the virus. Research related to the presence and abundance of aphid species in different parts of Serbia was carried out on 30 sites in four years: 2007, 2008, 2009 and 2010. Yellow water traps were placed in potato crop immediately after potato emergence. Samples were taken once per week until the drying of the above-ground mass. Over 11,500 specimens were collected and a total of 106 different taxa of aphids were identified. This publication analyses vector pressures for two most important potato viruses (PVY and PLRV) for different localities. The best conditions for the production of healthy seed potato exist on the Golija mountain, at altitudes above 1100 m, in comparison to other tested sites. The pressure of vectors on the mountain is low and so is the risk of potato plants viral infection because of late potato planting and low aphid occurrence.
