Research Progress on Chemical Ecological Management of Three Tomicus Species (Coleoptera: Scolytidae) in Yunnan Province of China1

Bark beetles in the genus Tomicus (Latreille) (Coleoptera: Scolytidae) are the most destructive pests of pine trees (Pinaceae) in the Yunnan region of China, causing significant damage to shoots and trunks, leading to extensive pine tree mortality. This has had a negative impact on the sustainabilityequally and healthy development of local forestry. Currently, the primary methods of managing Tomicus are through the removal of damaged wood and chemical control, which not only requires significant manpower, materials, and financial resources, but also poses a threat to the ecological stability of the environment and has led to the development of resistance to pesticides by the pests. This article introduces an overview of research in the field of chemical ecological management of Tomicus minor (Hartig), T. yunnanensis Kirkendall & Faccoli, and T. brevipilosus (Eggers) in Yunnan Province. This includes summaries of research on informational chemicals, artificial attractants, and volatiles from both host and nonhost plants. The aim of this review is to provide a comprehensive overview of chemical ecological management methods for these beetles, thus assisting researchers and research institutions in their efforts to provide for sustainability of our environmental resources.
