AB  - Ground beetle assemblages were compared in two oilseed rape fields with different management practices, in fallow and in succeeding winter wheat crop. A total of 11,615 specimens representing 52 species were collected over two years of sampling using epigeic pitfall and funnel traps. The ten most common species, represented 91% of the total number of specimens in oilseed rape, were Amara aenea (De Geer, 1774), Amara similata (Gyllenhal, 1810), Harpalus distinguendus (Duftschmid, 1812), Brachinus explodens Duftschmid, 1812, Poecilus cupreus (L., 1758), Calathus fuscipes (Goeze, 1777), Calathus ambiguus (Paykull, 1790), Poecilus punctulatus (Schaller, 1783), Poecilus sericeus Fischer von Waldheim, 1824 and Anchomenus dorsalis (Pontoppidan, 1763). Eight carabid species showed a clear preference for integrated oilseed rape management practice. Trapped beetles were three times more numerous in oilseed rape in integrated than in the field under organic management practice. Canonical Variate Analysis revealed that management practices applied on both fields in oilseed rape had a significant effect on carabid assemblages. Redundancy Analyses (RDA) showed that in the following year, in succeeding winter wheat crop, management practices applied in oilseed rape had a significant effect on carabid assemblages. Ground beetle activity on plants was registered in both oilseed rape management systems, but not on winter wheat plants. The most active carabids in crop canopy included A. similata, C. fuscipes, Calathus erratus (Sahlberg, 1827), A. aenea, C. ambiguus, Calathus melanocephalus (L., 1758) and H. distinguendus. In oilseed rape both management practices had a significant effect on carabid assemblages in crop canopy.

AB  - An experiment on three differently-managed agricultural fields in Ahlum, Germany, which aimed at establishing the impact of different management systems on the biodiversity of predators and decomposers, yielded a significant number of spiders parasitized by larvae of Trombidium brevimanum (Actinotrichida, Parasitengona, Trombidiidae). Spider data from the whole sampling period (September 2010-July 2012), indicated that ectoparasitic larvae were recorded only on spiders in pitfall traps in the period of June-July 2011. In this period, only eight species of Linyphiidae-out of 42 species assigned to nine spider families recorded from the study area-were parasitized by mites; considerable levels of parasitism were recorded on Erigone atra, E. dentipalpis, and Oedothorax apicatus. The highest prevalence of parasitism was recorded on the organic field for E. atra (29 %), while on the integrated and conventional fields significantly fewer parasitized spiders were observed. The preferred attachment sites on the spider host were regions with softer cuticle, especially regions on the carapace and on the abdomen, adjacent to the pedicel.

AB  - The Brassica pod midge (Dasineura brassicae Winn.) is an important pest in oilseed rape (Brasica napus L.). It develops two generations per year and overwinters in the larval stage in cocoons in soil. Immigration of the first generation adults lasted from the beginning of April until the end of May. Larvae developed in pods from mid-April to mid-June, causing pod deformation and cracking, which resulted in premature falling out of seeds and yield reduction. Pod damage amounted to 11.6%. The emergence of the second generation adults was detected at the end of May and in the first ten days of June. D. brassicae was found to lay eggs in healthy pods and no correlation was found with the cabbage seed weevil, Ceutorhynchus assimilis Paykull.

AB  - Agrobiont spiders are among the largest and most frequent groups of predators in agricultural areas, having an important role in pest control. Since land cultivation results in the reduction of their abundance several times a year, the pace of the recovery of the populations and their phenology primarily depends on the reproductive biology and development. The aim of this research was monitoring of the impact of crop rotation, insecticides use and field management on the life cycle of the agrobiont spider species Pardosa agrestis (Westring, 1861). The research was conducted on three experimental fields near the site Stari Žednik (Vojvodina, Serbia), which was managed by the conventional, integrated and organic methods. P. agrestis is characterized by the bimodal phenology and has the highest abundance in the organic management system in oil-seed rape fields. The study of insecticide application impact on the species phenology has shown that the use of pyrethroid agrochemicals has a negative impact on P agrestis phenology.

AB  - Our research of the genus Ceutorhynchus associated with oilseed rape was conducted in northern parts of Serbia (Stari Žednik, Subotica). A specific assemblage of eight weevil species was found. The most numerous were stem weevils Ceutorhynchus napi with 81% of all trapped specimens, followed by C. pallidactylus with 18%. The remaining six weevil specimens were C. obstrictus, C.erysimi, C. minutus, C. picitarsis, C. sulcicollis and C. typhae, comprising 1% of all trapped insects. Stem weevils C. napi and C. pallidactylus began to immigrate into the oilseed rape fields in autumn, as early as November 10 (BBCH 17-18). The maximum flight was recorded at the beginning of oilseed rape stem elongation (BBCH 22-25) on March 23. A new generation of C. pallidactylus emerged from oilseed rape fields in June (BBCH 76-88), while individual specimens occurred during the autumn. The majority of C. napi emerged in March next year, sporadically until May 7. As a consequence of C. napi dominance insecticide treatment should be performed earlier than usual, i.e. when C. pallidactilus is the primary target.
AB  - Istraživanje rilaša roda Ceutorhynchus koji se nalaze na uljanoj repici je bilo na severu Srbije. Našli smo specifičan skup od osam vrsta rilaša koji se sastojao od dominantne vrste veliki repičin rilaš, Ceutorhynchus napi, koji je imao učešće od 81% od ukupno sakupljenih jedinki i od subdominantnog rilaša C. pallidactylus sa učešćem od 18%. Preostalih šest vrsta rilaša je sadržao 1% ukupnog broja i to su bile vrste: C. obstrictus, C. erysimi, C. minutus, C. picitarsis, C. sulcicollis i C. typhae. Obe najbrojnije vrste, C. napi and C. pallidactylus, su rilaši stabla uljane repice i počinju da naseljavaju repicu već u jesen, počevši od 10. novembra (BBCH 17-18). Maksimalni let je registrovan 23. marta na početku izduživanja stabla (BBCH 22-25). Nova generacija C. pallidactylus eklodira tokom juna sa polja uljane repice (BBCH 76-88), ali se pojedinačni primerci pojavljuju i tokom jeseni. Većina odraslih C. napi eklodira naredne godine u martu, a sporadično sve do 7. maja. Posledica dominantnosti C. napi je potreba ranije primene insekticida nego kada je C. pallidactillus glavna meta.

abstract = "Our research of the genus Ceutorhynchus associated with oilseed rape was conducted in northern parts of Serbia (Stari Žednik, Subotica). A specific assemblage of eight weevil species was found. The most numerous were stem weevils Ceutorhynchus napi with 81% of all trapped specimens, followed by C. pallidactylus with 18%. The remaining six weevil specimens were C. obstrictus, C.erysimi, C. minutus, C. picitarsis, C. sulcicollis and C. typhae, comprising 1% of all trapped insects. Stem weevils C. napi and C. pallidactylus began to immigrate into the oilseed rape fields in autumn, as early as November 10 (BBCH 17-18). The maximum flight was recorded at the beginning of oilseed rape stem elongation (BBCH 22-25) on March 23. A new generation of C. pallidactylus emerged from oilseed rape fields in June (BBCH 76-88), while individual specimens occurred during the autumn. The majority of C. napi emerged in March next year, sporadically until May 7. As a consequence of C. napi dominance insecticide treatment should be performed earlier than usual, i.e. when C. pallidactilus is the primary target., Istraživanje rilaša roda Ceutorhynchus koji se nalaze na uljanoj repici je bilo na severu Srbije. Našli smo specifičan skup od osam vrsta rilaša koji se sastojao od dominantne vrste veliki repičin rilaš, Ceutorhynchus napi, koji je imao učešće od 81% od ukupno sakupljenih jedinki i od subdominantnog rilaša C. pallidactylus sa učešćem od 18%. Preostalih šest vrsta rilaša je sadržao 1% ukupnog broja i to su bile vrste: C. obstrictus, C. erysimi, C. minutus, C. picitarsis, C. sulcicollis i C. typhae. Obe najbrojnije vrste, C. napi and C. pallidactylus, su rilaši stabla uljane repice i počinju da naseljavaju repicu već u jesen, počevši od 10. novembra (BBCH 17-18). Maksimalni let je registrovan 23. marta na početku izduživanja stabla (BBCH 22-25). Nova generacija C. pallidactylus eklodira tokom juna sa polja uljane repice (BBCH 76-88), ali se pojedinačni primerci pojavljuju i tokom jeseni. Većina odraslih C. napi eklodira naredne godine u martu, a sporadično sve do 7. maja. Posledica dominantnosti C. napi je potreba ranije primene insekticida nego kada je C. pallidactillus glavna meta.",
