Population of corn ground beetle, found in the greatest number of 112 larvas/m made damages until the treatment. Survey on the number of live and dead larvas of corn ground beetle, 13 days after the treatment indicated that the greatest number of dead larvas (73.3%) was found in the plot treated with Cypermethtrin whereas 69.8% were found in the plot treated with the combination of insecticides, Cypermethrin + Monocrotophos. Only 20.7% of dead larvas were found in the first survey of the plot treated with the combination of insecticides Cypermethrin + Fenitrothion. The corn ground beetle population was reduced by 23.6% in the plot treated with Bensultap in the first survey. Spreading of the damage in wheat was reduced by the treatment but the crop declined in number, more or less, depending on the type of treatment.
