Abstract The sweetpotato whitefly Bemisia tabaci (Gennadius) was challenged with different combinations of matrine (insecticide) and Lecanicillium muscarium (entomopathogenic fungus). Our results revealed a synergistic relationship between L. on mortality enzyme activities B. . To illustrate the biochemical mechanisms involved in detoxification immune responses against both control agents, detoxifying antioxidant enzymes were quantified. After combined application , carboxylestrease (CarE), glutathione-s-transferase (GSTs) chitinase (CHI) decreased during initial infection period. Acetylcholinestrase (AChE) increased entire experimental period, whereas those superoxide dismutase (SOD), peroxidase (POD) catalase (CAT) later suppression enzymatic response following suggests strong effect agents. is possibly related to disturbance acetylcholine balance changes AchE as target insect (Ach) receptors which turn effects production. Therefore, our have complex processes action
