摘　　要：【目的】为了解云斑天牛在北美栎树上的发生为害情况。【方法】2020—2022年,采用野外调查与室内观察,研究云斑天牛在北美栎树上的产卵为害情况和生物学特性。【结果】娜塔栎受害最重,2022年受害株率达8.75%;云斑天牛产卵刻槽主要集中于树干高度50cm以下,占刻槽总数的91.44%;云斑天牛成虫产卵刻槽主要集中于胸径7~9 cm,占刻槽总数的82.62%。云斑天牛在崇仁县2年发生1代,世代不整齐并有“重叠”现象,主要以老龄幼虫在蛀道内或成虫在蛹室内越冬。【意义】调查结果为云斑天牛的防治提供理论依据和参考。[Objective]This study was conducted to understand the occurrence and damage of Batocera horsfieldi in North American oaks.[Method]Using field investigations and indoor observations,the oviposition and biological characteristics of Batocera horsfieldi in North American oaks were studied.[Result]Quercus nattallii was the most seriously damaged,with the damage reaching 8.75%in 2022.The oviposition groove of Batocera horsfieldi mainly concentrated below 50 cm in the height and 7-9 cm diameter of the tree trunk,which occupied 91.44%and 82.62%,respectively,of the total number of the oviposition groove.Batocera horsfieldi occurred once every 2 years in Chongren County,and mainly overwintered with elderly larvae in the cavity or adults in the pupal chamber.[Significance]The research results could provide references for its pest management.
