Lateral transfer of toxicants from male to female oriental fruit moth

Results of laboratory assays demonstrated that toxicants applied to male Grapholita molesta (Busck) are transferred to female moths, presumably during mating. The life-span, fecundity, and fertility of female G. molesta exposed to males treated topically with solutions of acetone plus either methoxyfenozide or chlorpyrifos, were reduced relative to control females exposed to acetone-only treated males. Similar results were obtained when males were treated with insecticide-laced powder.
