我国口岸从北美进口原木中截获山核桃小蠹(Scolytus quadrispinosus)、花旗松小蠹(S.unispinosus)和云杉小蠹(S.piceae),本文介绍了3种小蠹的形态特征、生物学等特征,并编制了与属内3种近似种的鉴别检索表,为进口北美木材中携带的小蠹属昆虫检疫鉴定提供参考。

Scolytus quadrispinosus,S.unispinosus and S.piceae were intercepted from logs imported from the North America.This paper introduces the morphological and biological characters of the three bark and ambrosia beetles,and a key to them with three similar species in the genus is given to provide reference for port quarantine.
