Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.
