Toxicity of insect growth regulator against diamond back moth, Plutella xylostella (L.)

Abstract

Laboratory studies were conducted to find out the toxicity of Rimon (Novaluron 10 EC), at chitin synthesis inhibitor on two growth stages, i.e., 2-day-old and 6-day-old larvae of diamond back moth. Maximum mortality inflicted by the IGR was 96.27% and 74.05% on young and old larvae respectively. The LC50 on 6-day-old larvae (0.00139%) was about 4 times more than the LC50 on 2-day-old larvae (0.00044%).
