Toxicity of Hexaflumuron as an insect growth regulator (IGR) against Helicoverpa armigera Hubner (Lepidoptera: Noctuidae)

The exploit of insect growth regulators (IGR) for insect pest management are good option because they do not accumulate in the environment and are less toxic to man and domestic animals. At the present study, a chitin synthesis inhibitor from insect growth regulator; Hexaflumuron was tested for its toxicity and side effects on the 4th instar larvae of Helicoverpa armigera Hubner. Estimated LC50 and LC90 values of leaf dip bioassay of Hexaflumuron on these larvae after 120 hours of treatment were 8.47, and 82.26 mg /L, respectively. Hexaflumuron at doses of 1, 3.2, 9.8, 31.6, and 100 mg/L were caused significant mortality on prepupae and pupae as compared to untreated control. Also abnormalities in adults were observed with treated pupae. We conclude that the sub-lethal and lethal effects of Hexaflumuron might exhibit significant effects on the population of H. armigera and can be used to its management.
