In maize plants the attack of European corn borer can cause significant damages, which can
lessen by insecticide application in crop protection. The aim of this study was to determine
the effect of insecticides on the total length of channels in maize plant stem formed by the
feeding of larvae Ostrinia nubilalis. The research was carried out in Maize Research Institute
different FAO ripening groups (ZP 434, ZP 600 and ZP 666) and three insecticides
chlorantraniliprole (200 g l-1), bifenthrin (100 g l-1) and lufenuron (50 g l-1)+(cypermethrin
(50 g l-1) + chlorpyrifos (500 g l-1)), which were applied only after the maximum flight of the
first generation to protect plants from attack of European corn borer. The result showed
significantly different total length of channels in the stem of plants, caused by feeding of the
larvae of European corn borer, which varied from the lowest on treatment with insecticide
chlorantraniliprole in maize genotype ZP 600 (170.00 cm) to the highes...t in maize genotype
ZP 666 (278.33 cm) on the control variant (without insecticide application). For all
treatments, the average value of total length of channels in stem, was the lowest 192.92 cm in
ZP 434, slightly higher 195.42 cm in ZP 600, while the highest average value of total length
of channels was 233.34 cm in maize genotype ZP 606. The established differences for total
length of channels depended on genotype and type of insecticide applied
