Abstract:

Selection of larvae of Heliothis virescens (F.) with permethrin at the LD90 level produced resistance. After 11 generations of continuous selection pressure, the LD50 in the F12 generation increased 37-fold compared to the LD50 of the F1. Cross-resistance to cypermethrin in this strain was high. In the F12 generation, LD50 and LD95 values were 7.9- and 50-fold greater, respectively, than LD50 and LD95 values of a strain collected in the field in 1981.
