摘要: Cotton bollworm, Helicoverpa armigera Hubner is the most important pest of cotton, tomato and chickpea in Iran. The has been found to develop resistance against conventional insecticides. Using insecticides with different mode action may result an appropriate control delay insecticide development. In this study, we attempted investigate lethal sublethal effects one conventional, two biorational on larvae at stages H. armigera, its adult longevity fecundity under laboratory condition. LC50 values chlorpyrifos, spinosad abamectin were 4.6, 62.26 460.5 ppm based formulated materials. results showed that chlorpyrifos more effective 3 rd instar cotton bollworm compared Furthermore, negatively affected adults emerged from treated third instars. But, had no significant effect adults. All tested seemed be bollworm. Spinosad might preferred due their environmental friendly impacts. Abamectin also markedly reduced female for exposed as instars spinosad. larvicidal reproductive biorationality suggest suitable integration into IPM program
