Abstract: Using identically timed and defined doses, four kinds of attractants, ZGHC-M-99, HYP-SH, A-3, and FJ-Ma-05, which were made in China, were used for baiting Monochamus alternatus in the fields of Fuyang in Zhejiang Province, eastern China. The results indicated that the four test attractants had a certain ability to trap M. alternatus, among which, ZGHC-M-99 and HYP-SH had a comparatively stronger effect than FJ-Ma-05. Compared with A-3, ZGHC-M-99 and HYP-SH did not display distinct difference on attraction effect on M. alternatus. Based on the number of adult M. alternatus captured by attractants, ZGHC-M-99 had the highest efficiency, followed by HYP-SH, A-3, and FJ-Ma-05, respectively. The chemical attractants seem to have different efficacies in different geographical areas.
