Abstract:

The symptom of Tetranychus viennensis treated with KFCE2 was investigated in this experiment. Several important enzyme systems, protein content, protease, glutathione-S-transferase(GSTs), acetylcholine esterase (AchE) and mnoamine oxidase, in T. viennensis treated with chloroform extract of Kochia scoparia were measured. The results that the protein content and the activity of protease in T. viennensis treated with the extracts of K. scoparia were hoisted and the activity of GSTs was induced indicated that some poisonous components in K. scoparia had aroused the detoxification of T. viennensis. But the activities of AchE and monoamine oxidase in T. viennensiswere inhibited. The inhibiting effects of AchE and monoamine oxidase meant the transfer of nerve impulse was interdicted and then caused the death of T. viennensis.
