AB  - Pesticides can have a lethal or sublethal effect on spiders and are able to influence their locomotion, activity, web building, reproduction and abundance. Effects of pesticides on spider morphological variations
have been poorly investigated. In this study, we explored the influence of pyrethroid insecticides (Fastac®,
Talstar® and Trebon®) on variations of linear measurements (body length, carapace and abdomen length,
carapace and abdomen width) and carapace shape in Oedothorax apicatus (Blackwall, 1850) from conventional, integrated and organic oilseed rape fields. Multiple applications of various pyrethroid insecticides
on the conventional field over a longer period of time influenced significantly the morphological variability
in female specimens only. These females had longer bodies with longer and wider carapaces and abdomens
in comparison with females from the organic and integrated fields. A wider posterior part of the carapace
and less protruded frontal part were detected in female spiders from the integrated and conventional fields.
We presumed that these results may be attributed to faster growth, which might be the consequence of a
pyrethroid hormetic effect on female individuals. In the case of male spiders, significant morphological differences between the experimental fields were not observed, probably due to their higher mobility.

AB  - Stem weevils (Ceutorhynchus pallidactylus and Ceutorhynchus napi) are significant pests of oilseed rape that farmers regularly suppress by insecticide treatments intended against Brassicogethes aeneus. Recent studies have shown that in some regions of northern Serbia C. napi is dominant, while C. pallidactylus prevails in others. Increased damage from stem weevils has elicited an exploration of the situation and a study of their phenology and effects of insecticides in three differently managed fields: conventional, organic and integrated. New findings regarding the phenology of stem weevils show that both species were sporadically present in our experimental oilseed rape fields as early as during autumn (from the end of October 2010, BBCH 17-18). The main period of stem weevil settlement is the end of winter and early spring. Maximum flight of both weevil species was recorded on March 23 at the beginning of oilseed rape (OSR) stem elongation (BBCH 22-25), and one week later in the organic field. There were no significant differences in the number of settled weevils among the three differently managed fields. The insecticide treatment against C. napi was applied two weeks earlier than the usual treatment against B. aeneus and C. pallidactylus. Thus, it is clear that insecticide treatment directed against B. aeneus and C. pallidactylus is not effective against C. napi. In this way, such a practice can contribute to an increase in OSR damage, and density of the next generation of C. napi. A new generation of C. pallidactylus emerged from OSR fields in June 2011, while the majority of C. napi emerged in March of the following year.
AB  - Ceutorhynchus pallidactylus i Ceutorhynchus napi su značajne štetočine uljane repice koje farmeri redovnu suzbijaju insekticidnim tretmanom protiv Brassicogethes aeneus. Nedavne studije su pokazale da u nekim regionima na severu Srbije dominira C. napi, a u drugim regionima C. pallidactylus. Povećane štete od stablovih rilaša ukazale su na potrebu praćenja njihove fenologije, efekata insekticida i uticaj agrotehnike. Utvrđeno je po prvi put da je pojava ovih insekata (C. napi i C. pallidactylus) na poljima uljane repice već tokom jeseni, od kraja oktobra 2010 (BBCH 17-18). Glavni period kada oni naseljavaju uljanu repicu je tokom kraja zime i na početku proleća. Maksimalni let je zabeležen 23. marta, u vreme izduživanja stabla uljane repice (BBCH 22-25). U odnosu na primenjenu agrotehniku nije bilo značajnih razlika u broju insekata koji su doletali. Registrovan broj doletelih imaga C. napi bio je 2,7 puta veći nego C. pallidactylus. U skladu sa tim, insekticidni tretman je bio 25. marta 2011. Posledica dominacije C. napi je potreba za primenom insekticida oko 2 nedelje ranije u odnosu na termin kada se suzbijaju B. aeneus i C. pallidactilus. Stoga je jasno da konvencionalna jednokratna primena insekticida za suzbijanje B. aeneus nije efikasna protiv C. napi i da takva praksa doprinosi tako velikim razlikama u brojnosti ova dva rilaša. Nova generacija C. pallidactylus izleće već tokom juna meseca iz zemljišta sa uljanom repicom (BCH 76-88) dok glavnina imaga C. napi izleće naredne godine u martu mesecu.

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  - The cabbage stem flea beetle (Psylliodeschrysocephala (L.) is an important pest of winter oilseed rape in Serbia. Beetles colonize oilseed rape in early October and are active in the field until first frost and wintertime. In autumn, adults can be seen laying eggs in the soil around plants. Larvae of P. chrysocephala developed intensively on leaf petioles in November, reaching their highest numbers at the end of the month. No infested plants were found in a conventional field, while 14.5% of all dissected leaf petioles were infested on an integrated field. On unprotected plants in an organic field, 76.0% of the plants were infested with larvae at the growth-stage BBCH 18-19, with 31.1% infested leaves on average. As a results, the number of plants was reduced by 51%, i.e. from 43.0/m2 recorded in the autumn to 22.0/m2 in the following spring. A new generation of P. chrysocephala beetles emerged from the soil in the first half of June and rapidly escaped the fields from almost dry plants. Our results showed that a part of the population stayed in aestivation and emerged in the following crop during the next season. On the following 5 March, 0.5 beetles/m2 were found in emergence cages in the organic field, while 0.81 beetles/m2 were found in the former trap crop.

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.

abstract = "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.

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  - Tokom dvogodišnjih istraživanja faune trčuljaka u agroekosistemima u severnoj Srbiji ukupno je ulovljeno 19.003 jedinki. Registrovano je 67 vrsta, klasifikovanih u 29 rodova. Dominantne vrste u usevu uljane repice i u usevu ozime pšenice su Harpalus distinguendus (Duftschmid, 1812), Amara aenea (De Geer, 1774), Poecilus cupreus (Linnaeus, 1758) i Amara similata (Goeze, 1777). Rodovi najbogatiji vrstama su Harpalus, Amara, Calathus, Poecilus i Brachinus. Sedam vrsta je novo za faunu Srbije: Calathus cinctus Motschulsky, 1850, Laemostenus complanatus (Dejean, 1828), Brachinus nigricornis Gebler, 1829, Cychrus attenuatus (Fabricius, 1792), Patrobus septentrionis Dejean, 1828, Anchomenus cyaneus Dejean, 1828 i Pterostichus leonisi Apfelbeck, 1904. Tri vrste su prvi put registrovane na teritoriji Vojvodine: Harpalus signaticornis (Duftschmid, 1812), Harpalus taciturnus Dejean, 1829 and Patrobus atrorufus (Ström, 1768). Nove vrste su sakupljene u epigejskim lovnim posudama. Šest vrsta je ulovljeno u usevu uljane repice, dok je jedna vrsta ulovljena u usevu ozime pšenice.

AB  - During two years of research on the epigeic fauna in agroecosystems of northern Serbia, which was conducted as a part of SEE-ERA NET PLUS project no. 51, 5488 spider specimens were collected at three fields with oilseed rape (Brassica napus var. oleifera), turnip rape (Brassica rapa x chinensis) and winter wheat (Triticum aestivum) as subsequent crop at Stari Žednik (Vojvodina). A total of 62 species from 15 families were identified. Pardosa agrestis and Xysticus kochi were the dominant species in the studied fields. Spider families with significant presence were Lycosidae, Linyphiidae, Thomisidae, Gnaphosidae, Theridiidae and Philodromidae. Seven species are new to the spider fauna of Serbia.
