Abstract

Nine commonly sprayed insecticides for the control of citrus insect pests were screened for toxicity to the adult parasitoid wasp, Aphytis sp. nt. chrysomphali. Based on the LC₅₀ the order of decreasing toxicity to Aphytis was: methyl parathion = monocrotophos > BPMC = deltamethrin > cyfluthrin = malathion > azinphos ethyl > triazophos > endosulfan. The selection of Aphytis sp. nr. chrysomphali with endosulfan has led to approximately eight-fold increase in resistance after four selection cycles.
