Abstract

Effects of structurally different insecticides, permethrin, chlorfluazuron, chlorfenapyr, prothiofos, methomyl, and thiocyclam on expression of hsp90, hsp70, hsp20.7, and hsp19.7 were examined using cultured cells of the cabbage armyworm, Mamestra brassicae. Significant induction of hsp90, hsp70, hsp20.7, and hsp19.7 expression was observed in response to chlorfenapyr. No induction was observed for the remaining five insecticides. The chlorfenapyr-induced expression was time-dependent and concentration-dependent. A significant reduction in expression levels of hsp70, hsp20.7, and hsp19.7 was observed in the time course when the cells exposed to chlorfenapyr were transferred to chlorfenapyr-free medium. These results suggest that hsp70, hsp20.7, and hsp19.7 might be useful to assess cellular distress or injury by chlorfenapyr.
