European Corn Borer, Ostrinia Nubilalis Hbn. (Lepidoptera, Crambidae) as a Pest

Abstract

European Corn Borer is a corn pest worldwide, present with different number of generation and races. The economic level of looses vary from 0-100 %. Apperance, harmffulness and voltinism are consequences of vegatation, agrometerological conditions, cultivars and technology. In Europe and north America are detected Z, E and H strain of pest. As a rule all strains are present in corn field. Exception is France, where is Z strain present in corn, and E strain in hop and mugwort. The presence of different pheromone isomer is the base of strain differentiation.

Kukuruzov plamenac je štetočina kukuruza prisutna sa različitim brojem generacija i tipova. Nivo ekonomskih gubitaka u godišnjoj proizvodnji varira od 0-100 %. Pojava, štetnost i voltinizam posledica su uticaja vegetacije, agrometeoroloških uslova, sortimenta i tehnologije gajenja. Na evropskom i severoameričkom prostoru utvrđeno je prisustvo Z, E i H tipa štetočine. Uglavnom su ovi tipovi prisutni u usevu kukuruza. Izuzetak je Francuska gde je Z tip identifikovan u kukuruzu, a E tip na hmelju i crnom pelinu. Razdvojenost na tipove uslovljena je prisustvom feromona i njihovom funkcionalnom praktičnom upotrebom u privlačenju mužjaka.
