Abstract:

Asemini is a Northern Hemisphere cerambycid tribe, and an important forest pest, mainly causing damage to coniferous plants. More important, as one kind of quarantine insects, Asemini can bring about many troubles in timber trade, therefore, the alien species should be paid more attentions and need to be quarantined in order to prevent them to be introduced to China. In China, there are 4 genus 26 species of Asemini. Host plants of Asemini include 15 genus 36 species of 7 families, and the main host plants are in Pinus , accounting for 30.56% of the total. A fauna analysis indicated that 15 species of Asemini distributed in the Palareartic Realm, accounting for 57.69% of the total. The species predominated in China, probably because gymnosperms were the main vegetable type in this region. This paper lists all the known species and genera of Asemini and their host plants in China, and discusses their distribution. The aim is to arouse the concerns of these insects and provide a reference for the relevant work.
