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  - The parasitoid species Ephedrus plagiator (Nees, 1811) (Hymenoptera: Aphidiinae) is one of the most important biological agents against pest aphids. We investigated whether this species was in competition with some other aphidiine species for the same hosts. We thus examined its potential in biological programs to control aphids. We applied an unsupervised artificial neural network, a self-organizing map (SOM), which classified the competitive parasitoids into seven groups. The SOM also visualized the distributional pattern of 31 parasitoid wasps along the neural network, revealing their competitive ability in relation to E. plagiator. Indicator value (IndVal) analysis quantified the competitive ability and showed that the most competitive species with regard to E. plagiator were Lysiphlebus testaceipes (Cresson, 1880), L. fabarum (Marshall 1896), L. cardui (Marshall 1896) and Binodoxys angelicae (Haliday, 1833). These species appeared in four different SOM groups and mostly parasitized the Aphis fabae Scopoli, 1763 (Hemiptera: Aphididae) host.

AB  - Considering the already observed trends of increasing air temperatures, changes in precipitation regimes, and extension of the growing season, as well as predictions that climate conditions in Serbia will deteriorate and the risks to farming will increase, the objective of this research is to assess the vulnerability of agriculture in Serbia to climate change, based on farmers' perceptions. A team of experts in all areas of agriculture and soil and water management compiled a questionnaire for a semi-open online survey. The snowball sampling approach was followed, relying on personal contacts and social media. In total, 141 farmers responded to the questionnaire. The data were evaluated using descriptive statistics. The differences by region, activity and topography were tested by ANOVA and Student's t-test. The feedback was used to assess the damages sustained by farmers due to climate change and reduced revenues in their respective areas of agricultural activity. Certain positive effects of climate change were also identified. A need for training in climate change impact mitigation is noted. The collected data were analyzed by descriptive statistics.

abstract = "Considering the already observed trends of increasing air temperatures, changes in precipitation regimes, and extension of the growing season, as well as predictions that climate conditions in Serbia will deteriorate and the risks to farming will increase, the objective of this research is to assess the vulnerability of agriculture in Serbia to climate change, based on farmers' perceptions. A team of experts in all areas of agriculture and soil and water management compiled a questionnaire for a semi-open online survey. The snowball sampling approach was followed, relying on personal contacts and social media. In total, 141 farmers responded to the questionnaire. The data were evaluated using descriptive statistics. The differences by region, activity and topography were tested by ANOVA and Student's t-test. The feedback was used to assess the damages sustained by farmers due to climate change and reduced revenues in their respective areas of agricultural activity. Certain positive effects of climate change were also identified. A need for training in climate change impact mitigation is noted. The collected data were analyzed by descriptive statistics. The surveyed farmers believe that the most important effects of climate change were periods of extreme high temperature, droughts, late spring frost, and hail. Climate change seems to be reducing yields, facilitating the appearance of new diseases and pests, and causing a lower tolerance to existing diseases and pests.

AB  - The aim of this research was to determine insect pests on vegetable crops in Smederevska Palanka area. By using standard methods, equipment and tools, insect pests that caused significant and less significant damages have been determined on vegetable crops: pepper, tomato, cucumber, melon, zucchini, cabbage, pea, bean, spinach and beet at the arable area at the Institute for Vegetable Crops. The most significant insect pests, causing the most damages were Frankliniella occidentalis and Tuta absoluta, and also several species of aphids (Brevicoryne brassicae, Myzus persicae, Aphis gossypii, Aphis fabae and Macrosiphum euphorbiae), stink bugs (Nezara viridula, Eurydema spp.) and flea beetle (Phyllotreta spp.). These insects caused direct and indirect damages. The most significant damages have been noted in green houses due to favourable conditions for insect reproduction and sufficient food supplies.
AB  - Cilj ovog rada je bio da se utvrde štetni insekti na povrću na području Smederevske Palanke. Na povrtarskim usevima Instituta za povrtarstvo, korišćenjem uobičajenih metoda, opreme i pribora, utvrđeni su štetni insekti koji su izazvali značajna ili manje značajna oštećenja. Na obradivom zemljištu posmatranog lokaliteta nalazili su se usevi paprike, paradajza, krastavca, dinje, tikvice, kupusa, graška, pasulja, spanaća i cvekle. Insekti koji su izazvali najznačajnija oštećenja su Frankliniella occidentalis i Tuta absoluta, a pored njih je utvrđeno više vrsta biljnih vaši (Brevicoryne brassicae, Myzus persicae, Aphis gossypii, Aphis fabae i Macrosiphum euphorbiae), stenica (Nezara viridula, Eurydema spp.) i buvača (Phyllotreta spp.). Ovi insekti su izazvali direktne i indirektne štete. Značajnije štete su pretrpeli povrtarski usevi u zaštićenim prostorima, zbog pogodnijih uslova za razmnožavanje i izobilja hrane za štetne insekte.

AB  - Aphids represent one of the most significant pest species in agroecosystems. In this study we investigated aphid diversity in Southeastern Serbia. We recorded 132 species, mostly infesting host plants from the families Asteraceae and Rosaceae. The most diverse genus was Aphis Linnaeus with 34 species. Within this genus, the most frequently sampled species was A. fabae Scopoli. Genera Uroleucon Mordvilko, Brachycaudus van der Goot and Dysaphis Börner were also represented by a large number of species.

AB  - Diversity and aphid flight activity in carrot crops have not been investigated in Serbia, so far. Monitoring of the flight activity of aphids, as potential vectors of carrot viruses was conducted at the locality of Opovo (South Banat) in 2017, using 12 color pan traps (6 green and 6 yellow). A total of 2108 individuals of winged aphids were collected and a total of 43 different aphid taxa were identified, including 12 species known as being vectors of carrot viruses. About 85% of collected aphid specimens were potential vectors of carrot viruses. Maximum population density of winged aphids and the highest flight activity of the potential vectors were observed in mid-June. The most numerous aphid species in pan traps were: Myzus persicae (54,7%), Therioaphis trifolii (12,8%), species of the genus Aphis (10,7%) and Acyrthosiphon pisum (9,3%). The differences in abundance of aphids and the number of recorded species in green and yellow water traps were not statistically significant, as confirmed by t-test.

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.

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  - Spotted alfalfa aphid Therioaphis trifolii (Monell) (Hemiptera, Aphididae) is one of the most important alfalfa pest on the world. Also, it is the most abundant alfalfa aphid in Serbia. This aphid cause damage to alfalfa directly by feeding and indirectly by vectoring plant-pathogenic viruses. Some notes of morphology, host plants, damage, biology, vector role and distribution of spotted alfalfa aphid are given. Abundance of this aphid on alfalfa, influence of climates changes on its abundance, as well as the most important natural enemies (Coleoptera: Coccinellidae and Hymenoptera: Aphidiidae) in Serbia were analyzed.
AB  - Tačkasta lucerkina vaš Therioaphis trifolii (Monell) (Hemiptera, Aphididae) jedna je od najznačajnijih štetočina lucerke u svetu, takođe, to je najbrojnija vaš na lucerki u Srbiji. Pored direktnih šteta koje nanosi ona je i vektor najznačajnijih virusa lucerke. U radu su prikazani osnovni marfološki podaci, biljke domaćini, štetnost, biologija razvića, vektorska uloga i rasprostranjenje tačkaste lucerkine vaši. Analizirana je njena brojnost na lucerki, uticaj klimatskih promena na povećanje brojnosti, kao i najznačajniji prirodni neprijatelji (Coleoptera: Coccinellidae i Hymenoptera: Aphidiidae) na teritoriji Srbije.

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  - BACKGROUND: Rape stem weevil (Ceutorhynchus napi Gyll.) and cabbage stem weevil (C.
pallidactylus Marsh.) can cause significant yield losses to oilseed rape (Brassica napus L.),
and chemical control is often needed to protect crops from these pests. The efficacy of six
insecticides, chlorpyriphos+cypermethrin, bifenthrin, alpha-cypermethrin, pirimiphos-methyl,
thiacloprid and tau-fluvalinate, was tested in a four year field trial. Besides the standard efficacy analysis expressed through the number of larvae per stem, a damage rating scale was
introduced and modelled using a regression model for ordinal categorical data.
RESULTS: Compared with the control, expressed through damage rating and larval number,
treatments with chlorpyriphos+cypermethrin and bifenthrin, showed higher efficacy in the
control of stem weevils compared to alpha-cypermethrin and pirimiphos-methyl. The lowest
efficacy was observed in treatments with tau-fluvalinate and thiacloprid.
CONCLUSION: This study showed that a combined efficacy evaluation expressed through
both damage rating scale and the count of larvae, supported by an ordinal regression model
for data analysis, is indispensable for obtaining accurate results.

AB  - The functional roles of different habitats may depend on the combined effect of local habitat management and the structure and composition of the surrounding landscape. However, this interaction is not well understood due to the common practice of pooling many different habitat types in one simple landscape metric (e.g., percentage crop area). In this study, we investigate the interactive effects of local and landscape factors on the abundance and species richness of aphids and their natural enemies, as well as primary parasitism and hyperparasitism rates. We selected 41 fields in Central Serbia with three disturbance levels at the local scale (wheat fields, alfalfa fields, and fallows) embedded in 15 landscapes that varied in percentage of annual crops, grasslands, and shrublands. We found ecosystem disservices to be promoted in wheat fields, where both aphid abundances and hyperparasitism rates were approximately threefold higher than in alfalfa fields and fallows. Concurrently, alfalfa fields supported at least twofold higher primary parasitism rates and predator (coccinellid) abundances than either wheat fields or fallows. The proportion of grasslands in the surrounding landscape had no effect on any organism group while shrublands appear to be important for both polyphagus predators and pests in some crops, a pattern not revealed when all semi-natural habitats in the landscape are pooled together. Our results imply that the roles of different habitat types at both local and landscape scales should be considered in a multifunctional agricultural management approach, which if adopted may provide better ecosystem services for multiple agroecosystem types.

AB  - BACKGROUND: Rape stem weevil (Ceutorhynchus napi Gyll.) and cabbage stem weevil (C. pallidactylus Marsh.) can cause significant yield losses to oilseed rape (Brassica napus L.), and chemical control is often needed to protect crops from these pests. The efficacy of six insecticides, chlorpyriphos + cypermethrin, bifenthrin, alpha-cypermethrin, pirimiphos-methyl, thiacloprid and tau-fluvalinate, was tested in a 4 year field trial. Besides the standard efficacy analysis expressed through the number of larvae per stem, a damage rating scale was introduced and modelled using a regression model for ordinal categorical data. RESULTSCompared with the control, expressed through damage rating and larval number, treatments with chlorpyriphos + cypermethrin and bifenthrin, showed higher efficacy in the control of stem weevils compared with alpha-cypermethrin and pirimiphos-methyl. The lowest efficacy was observed in treatments with tau-fluvalinate and thiacloprid. CONCLUSIONThis study showed that a combined efficacy evaluation expressed through both damage rating scale and the count of larvae, supported by an ordinal regression model for data analysis, is indispensable for obtaining accurate results.

AB  - Aphids (Hemiptera: Aphididae) are important pests of alfalfa all over the world. One of the most important ones is a blue alfalfa aphid - Acyrthosiphon kondoi Shinji. Morphology of the species is very similar to a green alfalfa aphid - Acyrthosipom pisum Harris. Saliva of A. kondoi is very toxic and this is why it is more important than other pest species. It can cause alfalfa wilting. Recently, A. kondoi was found in Europe, in Greece and France. It is expected to appear in other European countries.

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  - More than 40 different aphid species (Hemiptera: Aphididae) landing on plum and apricot trees were captured with Sticky shoot method and identified in the experimental orchards in Western Serbia during 2009-2011. The most abundant species found in 2009 and 2011 belongs to the genus Aphis. In 2010, Myzocallis spp. were most abundant. Specimens of the genus Muscaphis were found for the first time in Serbia. The aphid population dynamics varied greatly during the growing season. Spring peaks of aphid populations were evidenced in all 3 years in the period of May-June. Autumn peaks were recorded during the period of August-September in 2009 and 2011, but not in 2010. Twelve out of more than twenty species reported in the literature as a potential Plum pox virus (PPV) vectors were found in the orchards. Rhopalosiphum padi (Linnaeus), Aphis fabae Scopoli, Aphis craccivora Koch and invasive aphid species Aphis spiraecola Patch were the most common potential PPV vectors found. Other known PPV vectors were present in much lower specimen numbers in the following decreasing order: Hyalopterus pruni (Geoffroy), Phorodon humuli (Schrank), Brachycaudus helichrysi (Kaltenbach), Myzus persicae (Sulzer), Brachycaudus cardui (Linnaeus), Aphis gossypi Glover, Macrosiphum rosae (Linnaeus) and Metopolophium dirhodum (Walker). During all 3 years, statistically significantly greater number of known PPV vectors were captured on the plum trees during the spring peaks compared to the autumn peaks. The number of known PPV vectors captured during the spring peaks on the plum trees was also significantly larger than the number of known vectors captured on the apricot trees.
