Life cycle of the agrobiont spider species Pardosa Agrestis (Westring, 1861) (Arachnida: Araneae) from arable fields at Stari Žednik (Vojvodina, Serbia)

Životni ciklus agrobiontne vrste pauka Pardosa Agrestis (Westring, 1861) (Arachnida: Araneae) na poljoprivrednim površinama na lokalitetu Stari Žednik (Vojvodina, Srbija)

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. 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 neg...ative impact on P agrestis phenology.

Agrobiontni pauci se ubrajaju među najbrojnije i najučestalije grupe predatora na poljoprivrednim površinama, igrajući važnu ulogu u kontroli štetočina. Obrada zemljišta dovodi do redukcije njihove brojnosti paukova nekoliko puta u toku godine, pa tempo oporavka populacija agrobiontne araneofaune i njihova fenologija primarno zavise od njihove reproduktivne biologije i načina razvića. Ciljevi istraživanja su se prevashodno odnosili na praćenje uticaja smene useva, korišćenja insekticida i načina obrade zemljišta na životni ciklus agrobiontne vrste pauka Pardosa agrestis (Westring. 1861) na tri eksperimentalne površine na lokalitetu Stari Žednik (Vojvodina, Srbija), obrađivane konvencionalnom, integrisanom i organskom metodom. Vrsta P. agrestis se karakteriše bimodalnom fenologijom, pri čemu je najveću brojnost imala na poljoprivrednim površinama sa usevom uljane repice tretiranom organskom agrotehničkom metodom. Razmatranje potencijalnog uticaja upotrebe insekticida na fenologiju ove v...rste je pokazalo da piretroidne agrohemikalije imaju negativan efekat.
