The effects of pirimicarb (a neurotoxin), buprofezin (an insect growth regulator) and pymetrozine (an antifeedant) on Coccinella undecimpunctata were assessed by studying the survival and development of all immature stages and the survival and reproductive performance of adults. Insecticides were sprayed at doses recommended by the manufacturers for the control of aphids and/or whiteflies. None of the three insecticides had a significant effect on the survival of C. undecimpunctata eggs. When sprayed on larvae, buprofezin significantly reduced survival to adulthood to 45% for the control and other insecticide treatments. Rates of adult survival, fecundity, and fertility, and the percentage of egg hatch, were not significantly different between control and insecticide treatments. Thus, larval stages were more susceptible to insecticides than were adults. In general, pirimicarb and pymetrozine had no adverse effects on immature or adult stages of C. undecimpunctata, and hence are suitable for IPM of sucking pests.
