Abstract: The trapping test of adult Hyphantria cunea with different lure cores was completed on the basis of the four-generation trend monitoring test of Hyphantria cunea carried out by the National Forestry and Grass Administration. Through the experiments of trapping quantity（test A）, setting distance（test B） and setting height（test C） of three kinds of lure cores（one made in Japan and two made in China）. The test results showed that the domestic core provided by Zhongjie Sifang is superior to that produced in Japan, followed by that provided by a university in Nanjing. The experimental results can provide data support for the selection of adult control equipment of Hyphantria cunea.
