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  - 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 effects of insecticides that are commonly used for conventional and integrated oilseed rape (OSR) management on ground beetles were studied. Monitoring of harmful species showed that only insecticides intended against Ceutorhynchus napi should be applied. There were no differences in beetle numbers and phenology of settling of C. napi in the OSR fields that received different management practices. The type of OSR management has a primary and significant impact on ground beetles abundance. Early in the spring, ground beetles settled more massively on the non-tilled OSR field with abundant weed cover and mulch on soil surface. However, there were no significant differences in species richness between the OSR fields managed differently. A total of 22 species were recorded. Early in the spring, the granivorous ground beetles Amara aenea (47.3%) and Harpalus distinguendus (32.5%) were dominant. When insecticides were applied, immigration of ground beetles began, so that their adverse effect was minimal. In both management systems the number of ground beetles and their diversity increased after spraying. In conclusion, no significant harmful effects of the insecticides on ground beetles were detected in OSR fields managed in two different ways.

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.

abstract = "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.

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  - 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  - 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  - 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.

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  - It's been over 20 years since Diabrotica virgifera virgifera was introduced in Serbia. Its expansion and colonization of the territory was quickly, over a few years. D. v. virgifera is present in all's territories where corn is grown in Serbia. Damage to corn in the rotation have occurred during the period of its territorial expansion and population build up. In recent years, losses are small and occur on maize in monoculture. The main control measures in D.v. virgifera is crop rotation. The mass use of crop rotation in the cultivation of maize has led to a reduction in damages.
AB  - Prošlo je više od 20 godina od kako je kukuruzova zlatica, D. v. virgifera, uneta u Srbiju. Njeno širenje i naseljavanje teritorije je bilo brzo, tokom svega nekoliko godina, pa je sada prisutna na svim teritorijama gde se gaji kukuruz u Srbiji. Štete na kukuruzu u plodoredu su se javljale u periodu njenog teritorijalnog širenja i umnožavanja brojnosti populacije. Zadnjih godina štete su male i javljaju se na kukuruzu u monokulturi. Glavna mera suzbijanja D. v. virgifera je plodored. Masovna primena plodoreda u gajenju kukuruza je dovela do smanjenja šteta.

AB  - Ethanol solutions of five fractions obtained from essential oil of sweet basil Ocimum basilicum L. (Lamiales: Lamiaceae) (F1-F5) were tested for their antifeedant properties against 2nd instar gypsy moth larvae, Lymantria dispar L. (Lepidoptera: Lymantriidae), in laboratory non-choice and feeding-choice experiments. Prior to bioassays, the chemical composition of each fraction was determined by gas chromatography analyses. Significant larval deterrence from feeding was achieved by application of tested solutions to fresh leaves of the host plant. The most effective were F1 (0.5%), F4 (0.05, 0.1, and 0.5%), and F5 (0.1 and 0.5%), which provided an antifeedant index > 80% after five days. A low rate of larval mortality was observed in no-choice bioassay. In situ screening of chlorophyll fluorescence as an indicator of plant stress level (assessed by the induced fluorometry) confirmed that the tested compounds did not cause alternations in the photosynthetic efficiency of treated leaves.

AB  - The study of Dasineura brassicae (Winn.) (Diptera: Cecidomyiidae), was conducted in northern Serbia, in the 2011, in conventional, integrated and organic system of cultivation of oilseed rape (Brassica napus L.), and in 2011/12 on the winter wheat, which was in rotation with oilseed rape. Pest develops two generations per year and overwinters as a larva in a cocoon in the soil. Immigration of adults of the first generation lasts from the beginning of flowering, April 12 (BBCH 60-62), up to achieving the final size pods, May 26 (BBCH 77-78). The female lays eggs in pods that can warp and crack, the seeds fall out, resulting in a decrease in the yield of oilseed rape. Infestation pods of oilseed rape from 3 different cropping systems is 2.5 to 11.6%.There is a statistically significant difference between the mean number of larvae and adults of D. brassicae in an integrated with respect to the conventional and organic oilseed rape management cropping system. It was found that D. brassicae lays eggs in undamaged pods and that there is no correlation with Ceutorhynchus obstrictus (Marsham). Due to the low number of adults and their appearance in the late stage of oilseed rape development second generation of D. brassicae is of no importance for the production. During the second year of study, in winter wheat fields, emergence of D. brassicae is not registered indicating the duration of diapause for more than one year.

Vrsta razvija dve generacije godišnje a prezimljava kao larva u kokonu u zemljištu.

Ženka polaže jaja u ljuske koje se deformišu i pucaju, semenke ispadaju, što ima za posledicu smanjenje prinosa uljane repice. Oštećenost ljusaka u tri sistema gajenja uljane repice iznosi 2,5-11,6%. Postoji statistički značajna razlika između brojnosti larava i imaga D. brassicae u integralnom u odnosu na konvencionalni i organski sistem gajenja uljane repice. Utvrđeno je da D. brassicae polaže jaja u zdrave ljuske i da nema korelacije sa Ceutorhynchus obstrictus (Marsham). Zbog malog procenta eklodiranih imaga (0,57-1,5%) u kasnoj fenofazi domaćina, druga generacija D. brasicae u našim uslovima nema značaja u proizvodnji uljane repice.

AB  - iColorado potato beetle (CPB, Leptinotarsa decemlineata Say) resistance is one of the limiting
factors in potato production in some regions of Serbia. Imidacloprid is first introduced neonicotinoid
insecticide in use for effective CPB control. Introduction of such insecticides with novel mode of action
and physicochemical properties, demands investigations on resistance risks and management tactics.
Primary candidates for cross resistance are insecticides acting on same target sites (such as bensultap,
with CPB resistance reported), although other cross resistance patterns between apparently unrelated
insecticides are not uncommon. Results of the investigations presented in this paper refers to the
resistance of CPB adults to 3 insecticides - imidacloprid, bensultap and cypermethrin, most commonly
used by farmers in recent years. First generation adults from nine field populations in first and four
representative populations in second year of investigation were tested by topical application.
Resistance ratios for bensultap ranged from 1.0 to 645.3 (LD50 from 0.04 – 25.81 μg/insect).
Cypermethrin resistance ratios ranged from 1.0 to 60.0 (LD50 from 0.02 – 2.05 μg/insect). Imidacloprid
resistance ratio was from 1.0 to 82.9 (LD50 from 0.0039 – 0.0323 ng/insect). Based on our results there
was no correlation between resistance levels for bensultap and imidacloprid. Although LD50 values for
imidacloprid were very low, significant resistance ratios obtained in these investigations, together with
threads of cross-resistance and importance of conserving field efficacy of neonicotinoids, strongly
recommands systematic resistance monitoring as important resistance management tool.

AB  - Western corn rootworm (WCR) was registered for the first time in Europe near the Surčin international airport in Serbia in 1992. The spread of WCR on the territory of Serbia and its population density increased fast. The Serbian territory was entirely populated in the following few years, while major damages occurred on corn grown for two or more years in the same field. Data on damages caused to over 140,000 ha under corn until 1999 were collected by organized monitoring. After 2000 and 2003, population abundance of D.v. virgifera, as well as the number of damaged corn fields, significantly decreased due to drought and application of crop rotation. Corn rootworm has one generation per year. It overwinters in the egg stage. Under the climatic conditions of Serbia larvae hatching starts around May 15th. The highest number of larvae on root is observed around June 20th when feeding is most intensive and plants become lodged as they lose roots. First adults emerge by the end of June. Their abundance increases during July and reaches maximum by the end of the month. From the second decade of August the abundance decreases. Adults are present in the field until the first frosts. Larvae are much more harmful and significant than adults. Larvae feed on roots or into roots by boring. Roots can be entirely destroyed under heavy attack and the host plants lodged already at the end of June. Under our climatic and agrotechnical conditions, adults are sporadic pests. Adults are a threat only when sowing is done after the optimal sowing date or in case of stubble corn sowing. Crop rotation is an efficient and most widespread means of WCR control. No damage on corn grown in crop rotation has been registered in Serbia for now. In the first year of production corn does not require protection from Diabrotica virgifera virgifera LeConte larvae. Several insecticides have performed high efficacy by application at sowing and have been registered for commercial use. On the other hand, soil insecticides have never been applied on a significant area in Serbia.
AB  - Kukuruzova zlatica je prvi put registrovana 1992. godine pored međunarodnog aerodroma Surčin. Širenje zlatice po teritoriji Srbije i porast gustine njene populacije je bilo brzo. Celokupna teritorija Srbije je naseljena u narednih nekoliko godina, pri čemu su se značajne štete javile na kukuruzu u ponovljenoj setvi. Sakupljeni su podaci o štetama na preko 140.000 ha kukuruza u periodu do 1999. godine. Posle 2000. i 2003. godine brojnost popualcije D.v. virgifera kao i broj oštećenih kukuruzovih polja je značajno smanjen zbog suše i masovne primene plodoreda. Kukuruzova zlatica ima jednu generaciju godišnje. Prezimljava u stadijumu jajeta. U klimatskim uslovima Srbije piljenje larvi počinje oko 15. maja. Najveći broj larvi se nalazi na korenu kukuruza oko 20. juna kada je ishrana larvi najintenzivnija. Zbog gubitka korena dolazi do poleganja biljaka. Odrasli insekti se javljaju krajem juna. Njihova brojnost raste tokom jula i dostiže maksimum krajem tog meseca. Od druge dekade avgusta brojnost imaga opada. Odrasli insekti se mogu naći u polju sve do prvih mrazeva. Larve se hrane na korenu ili se ubušuju u njega. U slučaju velikog napada koren može biti potpuno uništen i takve biljke već krajem juna poležu. U našim klimatskim i agrotehničkim uslovima odrasli insekti su sporadične štetočine. Oni mogu biti štetni u slučajevima kasnije setve ili postrne setve. Plodored je efikasan i najrasprostranjeniji način suzbijanja kukuruzove zlatice. Do sada se u Srbiji nisu javile štete na kukuruzu u plodoredu. Stoga se u kukuruzu u plodoredu ne primenjuju zaštitne mere. Više insekticida pokazuje dobre rezultate u suzbijanju kukuruzove zlatice kada se primenjuju sa setvom i imaju dozvolu za primenu u Srbiji. Međutim, zemljišni insekticidi nisu nikada do sada primenjeni na većim površinama za suzbijanje kukuruzove zlatice.
