Genetic Structure of (Hope) in Qinling-Daba Mountains and Expansion Trend: Implications for Pest Prevention and Management.

Pine wilt disease (PWD), caused by , severely threatens global pine forests. is the primary vector of in East Asia. Understanding the population structure and evolutionary forces of vector insects is critical for establishing effective PWD management strategies.

Population Density and Host Preference of the Japanese Pine Sawyer () in the Qinling-Daba Mountains of China.

is a serious trunk-boring pest and is the most important and effective vector of the pine wood nematode , which causes pine wilt disease. The pine wilt disease poses a serious threat to forest vegetation and ecological security in the Qinling-Daba Mountains and their surrounding areas. In order to clarify whether the population density of larvae is related to the host preference of adults, we investigated the population density of overwintering larvae and explored the host preference of adults on , , and .
