The survival times of male (a) and female (b) adults developed from larval survivals of insecticide treatments: The blue-colored bars indicate the results of insecticides applied before larval release and the orange-colored bars represent the results of insecticides applied after the larvae had burrowed inside the bolls. The different letters superscripts to the same colored bars indicate that the treatments are significantly different from each other. The means were separated by Tukey’s Least Significant Difference (LSD) test at P ≤ 0.05 level of significance
