Abstract: The attraction effects of the hemolymph of Semanotus sinoauster and Clytus valtus Fairmaire, the excrement of S. sinoauster and the extracts of the excrement to Scleroderma sichuanensis Xiao were studied in this article. The result shows that the hemolymph can attract S. sichuanensis Xiao to feed and the excrement or the extracts of the excrement can induce the parasitoid to search for its hosts. The amino acids and carbohydrates in the excrement have the kairomone activity separately through further segregation, purification and identification. It also shows that the amino acids content in the excrement is 1.9090 mg/g, which is 1/67 of content in the hemolymph and the carbohydrates content is 4.8890 mg/g, which is 1/5.6 of content in the hemolyph.
