Abstract: In order to explain physiological and biochemical mechanisms of the increasing host range of Anoplophora glabripennis and develop sustainable control measures, activities of five kinds of detoxification enzymes in A. glabripennis fed on Acer negundo (AN), Betula platyphylla (BP), Populus euphratica (PE), and Fraxinus chinensis (FC) were measured. The detoxification enzymes were carboxylesterase, glutathione S-transferase(GSTs), acid phosphatase, alkaline phosphatase and polyphenol oxidase. The results showed that carboxylesterase activity of beetles fed on AN and BP was significantly higher than those fed on PE and FC (P<0.05). Glutathione S-transferase activity of beetles fed on BP was significantly higher than those fed on other 3 host trees (P<0.05). Alkaline phosphatase activity of beetles fed on AN was significantly higher than those fed on PE and FC (P<0.05). The results indicated that the host trees had significant effect on the activities of carboxylesterase, glutathione S-transferase and alkaline phosphatase. The activities of acid phosphatase of beetles fed on the four kinds of host trees were not significant (P>0.05). The similar results were also found on polyphenol oxidase. These results indicated that the host plant had little effect on activities of acid phosphatase and polyphenol oxidase.
