Corn borer, Ostrinia nubilalis Hbn. is a pest that can cause significant
economic damage on maize crop. The aim of this work is study variation of
percentage damaged maize plants, number of perforation and length of
channals on plant stem, caused by feeding of larvae corn borer, under
application of insecticides. For study included three maize genotypes ZP 427,
ZP 555 and ZP 606 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))], were applied 15 days from the peak of the second
generation of corn borer. Experiment was set up in three repetition on a basic
plot of 10.5 m2
, conducted on field of Maize Research Institute “Zemun Polje”
in 2020. The results showed that on control (without insecticide) in all three
maize genotypes, the highest number of damaged plants ~ 95% which was
significantly higher than on variant treatments by insecticide. The percentage
of damag...ed plants for all three maize genotype was the lowest on treatment
with chlorantraniliprole 72%, higher on treatment with insecticide bifenthrin
(82%; 86%;80%) and on treatment with
[lufenuron+(cypermethrin+chlorpyrifos)] – (84.8%; 87.2% ; 81.6%). On
average, for all treatments, genotype ZP 427 had the smallest number of
perforation (~41) and the smallest length of channels in the stem (189 cm),
while ZP 606 had the smallest number of damaged plants (82.56%). The
established differences for intensity of attack and degree of damages varied
depending on genotype and type of applied insecticide.
