The toxicological and biochemical characteristics of glutathione S-transferases (GSTs) and superoxide dismutase (SOD) in Liposcelis bostrychophila and L. entomophila were comparatively investigated. Compared to their counterparts in L. entomophila, the activities of both GSTs and SOD from L. bostrychophila were significantly higher (P < 0.05), indicating that there was a stronger ability to eliminate the toxicants in the latter. The inhibition kinetics of insecticides revealed that dichlorvos and paraoxon possessed excellent inhibitory effects on GSTs in vitro, while there were some activated effects of chlorpyrifos on GSTs, more significant in L. entomophila. As for SOD in vivo, dichlorvos and chlorpyrifos had some inhibitory effects under the condition of sublethal concentration. However, the situation of carbosulfan was a little complex. Within the first 3 h treatment period there were facilitated effects on SOD in L. bostrychophila, and some expressed inhibitory effects. While in L. entomophila carbosulfan always possessed inhibitory effects on SOD.
