Sažetak

The aim of this study was to determine the effectiveness of a chemical treatment against larvae of the European corn borer (Ostrinia nubilalis Hubner). The experiment was set up in 2010 and 2011 in Čepin (eastern Croatia in two treatments: control treatment and insecticide treatment). The trial involved two hybrids of FAO group 400: PR37N01 and PR37F73. Biology of pests was monitored in order to determine population size and larvae development stage as well as the optimal time of insecticide application. After determination of thresholds, maize was treated with chemical formulations of active substance dimethoate. Towards the end of vegetation, length of stem damage, number of larvae in maize stalk and ear as well as grain yield were recorded by dissection of maize stalks. Statistical analysis shows that year, hybrid and chemical treatment significantly influenced the incidence of this pest and justified the use of chemical preparations with mandatory monitoring biology of this pest.
