Effects of selected biopesticides on the whitefly Bemisia tabaci and its natural enemies

The sweetpotato whitefly (Bemisia tabaci) is a common pest of numerous crop species and can cause serious damage via feeding activity and virus transmission. Growers frequently manage whiteflies using synthetic insecticides. However, there is concern that synthetic treatments cause adverse effects on human or environmental health, and repeated use has led to insecticide resistance in whiteflies. Biopesticides offer a more environmentally friendly alternative management tool to conventional pesticides. Natural enemies can provide an additional level of whitefly control; however, it is important to know if these pesticides have a negative impact on these natural enemies. In this study, we investigated the effects of selected biopesticides on B. tabaci and on some of its natural enemies. We used field, greenhouse, and laboratory bioassays to evaluate performance and behavioral responses. This study provides insight into the efficacy of biopesticides in whitefly management and their effects on natural enemies. Understanding the full impacts of pesticides on target and non-target arthropods will allow growers to make informed decisions when selecting pest management strategies.
