Investigation of Trunk Borer Species in Haikou Forest Farm of Kunming

为明确昆明市海口林场的蛀干害虫种类,从2016年7月至2017年9月,采用漏斗诱捕器和挡板诱捕器对海口林场的蛀干害虫进行调查,共收集到昆虫34 487头。经鉴定,蛀干害虫隶属1目4科38属41种,常见种14种。种类上以天牛科(Cerambycidae)居多,数量上小蠹科(Scolytidae)居多,4个科中数量最多的分别是小粒绒盾小蠹(Xyleborinus saxeseni)、松墨天牛(Monochamus alternatus)、马尾松角胫象(Shirahoshizo patruelis)和红缘吉丁(Buprestis fairmairci)。文中对41种蛀干害虫中的14种常见种的形态特征进行了描述,并根据蛀干害虫类群、数量、发生林分及发生规律进行分析,提出相应的防治措施。

In order to know the species of trunk borers in Haikou Forest Farm , the fnnel trap and the cross baffle trap were used to collect 34487 trunk borers from July 2016 to September 2017. The results showed that 41 species of trunk borers belonged to 38 genera, 4 families and 1 order with 14 common species. Cerambycidae had the most species and Scolytidae had the biggest population.
