The results showed that there were no significant differences in antenna morphological characters and sensor's distribution between the male and female. Majority of sensilla spreaded on the club of the antennae and occupied 98. 4% of all sensilla. The sensilla could be divided into four types: zigzag sensillum, bud-shaped sensillum, basiconca sensillum and chaeticum sensillum. These types respectively accounted for 57.7%, 28.6%, 12.6%, and 1.1% of the total sensilla. Zigzag sensilla distributed on all parts of antennae, among which sensilla on the club accounted for 99. 2% of total sensilla. However, sensilla on the scape and fanicles had approximately 0. 8% . Bud-shaped sensilla were buried beneath the zigzag sensilla on the club or distributed on the edges of club. Basiconca sensillum scattered on the edge of the club, and blended with bud-shaped sensilla while chaeticum sensilla distributed on the joint of the scape and funicle.10amorphology10aScolytus schevyrewi1 aFan, Linhua1 aLi, Yonghong1 aZhang, Jintong1 aLuo, Yuoqing1 aZong, Shixiang1 aYang, Meihong  uhttps://weevil.myspecies.info/antennae-structure-scolytus-schevyrewi-observed-scanning-electron-microscope
