Pine wilt disease (PWD) is one of the most important forest tree diseases, especially in the East Asian countries of Japan, China, and Korea. The Japanese pine sawyer, Monochamus alternatus Hope, is the PWN vector for Japanese red pine and Japanese black pine while Monochamus saltuarius Gebler is the vector for Korean white pine. Various control methods, such as aerial pesticide applications, biological control using parasitoids and fumigant such as methyl bromide are used. But the PWD still has spread. Therefore, we were selected effective aerial insecticides. Susceptibility of M. saltuarius and M. alternatus adults were investigated using 9 insecticides which are available in the market in Korea. And then, we tested them to the Apis mellifera to vertify the environmental impact.
