Sweetpotato Whitefly and Parasite Populations in Sprayed Cotton Plots

Abstract

Two insecticide applications were made to cotton in late August and early September. Higher Bemisia tabaci populations were observed in the malathion treatment, as sampled by vacuum samples, and in the DyloxR and malathion treatments, as sampled by yellow sticky traps. Generally, the numbers of parasites collected were higher in untreated check plots than in the insecticide treated plots.
