Sažetak
European corn borer (ECB) tunnel and feed within vascular tissues of maize whereas disrupt water and nutrient transport within plants. Occurred injuries predispose plant to stalk breakage and ear droppage, and may result in serious maize yield losses. The aim of this work is to evaluate susceptibility of maize hybrids to ECB. Two years of field studies were conducted among seven maize hybrids at Croatian site. Susceptibility to ECB was assessed by measuring tunnel length and number of ECB larva in dissected maize stalks and grain yield. Intensity of ECB attack in both years was 100%. Number of larva detected in plants across years was similar. Significant difference was observed for tunnel length since in 2008 it was longer for 22 cm in average for all hybrids compared to 2007. The extent of tunneling injury ranged between hybrids from 13.70 to 29.20 cm in 2007, and from 40.84 to 64.42 cm in 2008. Significant differences for tunnel length and number of larva among hybrids were found in both years. One larva in average was found in each dissected stalk. A positive correlation between tunnel length and number of larva has been observed for all hybrids in both years with exception of one hybrid in 2008 year. Our results indicate substantial variability among hybrids, and hybrid OsSK 602 showed tolerant characteristics. However, all hybrids proved to be susceptible to ECB but able to produce high yields under severe ECB infestation.
