Harmfulness and control of western corn rootworm

Abstract

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.

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.
