Effects of different irrigation levels on European corn borer (Ostrinia nubilalis (Hübner)) populations

In In this study, the effects of different irrigation treatments (I(100), I(50,) I(30)) on the European corn borer (Ostrinia nubilalis hübner) populations in different corn genotypes (Ada-9510, Samada-07, Ada-523, Kompozit Arifiye) were investigated. As the average, the highest yield (1582.33 kg da(-1)), low number of live larva + pupa per plant (2.70), tunnel length (7.73 cm) were observed in I(100) x ADA-523 interaction while the lowest yield (896.00 kg da(-1)) was observed in I(30) x Kompozit Arifiye interaction. The largest European corn borer population was observed in full irrigation (I(100)) and the lowest population was observed in excessive water deficit (I(30)) treatment. The European corn borer preferred the Kompozit Arifiye genotype. It was concluded that the genotypes should be tested under water-stressed and non-water-stressed conditions for resistance to the European corn borer and live larva and tunnel length could be used as a screening parameter.
