摘要
松瘤小蠹Orthotomicus erosus Wollaston隶属于鞘翅目Coleoptera象甲科Curculionidae小蠹亚科Scolytinae瘤小蠹属Orthotomicus,又被称为Mediterranean pine engraver(地中海松树雕刻家),是潜在的重要害虫,在我国分布广泛,云南省的普洱、西双版纳和丽江有分布。2020年9月,首次在云南省玉溪市峨山县玉白顶自然保护区的云南松Pinus yunnanensis上发现松瘤小蠹,且因其危害造成大面积松树死亡。玉溪市峨山县是松瘤小蠹的地理分布新记录,云南新增1个昆虫地理分布小区即云贵高原小区。对松瘤小蠹的分类地位和形态特征、雌雄成虫及其与近缘种的鉴别特征、地理分布和寄主植物、新发生地和危害情况进行阐述,并针对该虫所在的野生动植物保护栖息地提出相应的防治策略建议。
Orthotomicus erosus Wollaston belongs to the genus Orthotomicus of Scolytinae of Curculionidae of Coleoptera,also known as Mediterranean pine engraver,which is a potentially important pest,and is widely distributed in China,including Xishuangbanna,Lijiang and Pu′er in Yunnan province.In September 2020,O.erosus was the first found on Pinus yunnanensis in Yubaiding Nature Reserve,E′shan county,Yuxi city,Yunnan province,and its damage caused death of a large area of pine tree.E′shan county of Yuxi city is a new record of the geographical distribution of O.erosus,and a new insect-geographic community,namely Yunnan-Guizhou Plateau community,was added in Yunnan province.The classification status and morphological characteristics,the identification characteristics of relative species and between males and females,the geographical distribution and host plant,overview of the new site,the occurrence and hazard situation of O.erosus were expounded,and the corresponding control strategies were proposed according to the bark beetle live in the wildlife conservation habitat.
