Determination of Behavioral Responses of Scleroderma sichuanensis with Learning Experience to the Volatiles of Host and Feces of Clytus valiandus

By Y type olfactometer and electroantennogram, studies were made of the learning effect of Scleroderma Sichunensis in early emergence period to the in duction of pepper volatiles and mixture of Clytus valiandus feces and sawdust. The behavioral responses to different concentrations of volatiles were compared between S. sichunensis with learning experience and those without learning experience, which could be a way to improve the prevention efficiency of S.sichuanensis.The results showed that the the highest behavioral response rate of S.sichuanensis was 66.67%, induced by 10 g·mL^-1 of pepper branches volatiles in emergence period,which were significantly different from the other 9 treatments (P<0.05). The second highest rate was 64.44% for S.sichuanensis induced by 10 g·mL^-1 insect feces and sawdust volatile flavor. And the rate was lowest when S.sichuanensis was induced by 0.01 g·mL^-1L of pepper branches and insect feces sawdust volatile. The pepper volatiles and Clytus valiandus feces learning process for S.sichuanensis showed positive effect on prevention, and pepper shoots volatiles were the most prominent prevention effect.
