In: Mansoura University Journal of Agricultural Sciences 2003.v.28(3)Summary: Field experiments were conducted at two successive growing seasons (2000 & 2001) at Sakha Agricultural Research Station to evaluate the efficiency of some conventional insecticides on the larvae of bollworms. Data showed that in general, pyrethroides were the most efficient compounds during the two seasons. The effect of all tested compounds seems to be cumulative from one spray to the other. It can conduded that most of the obtained percent of reduction reflected a moderate effect and so, repeated application of any insecticides during the same season must avoided.
