摘　　要：2020年5月起对大连市松材线虫病疫区内天牛种类进行调查和研究,旨在进一步明确松材线虫病的传播媒介昆虫。在大连市甘井子区的松林22个小班内悬挂诱捕器,每隔7 d收集一次诱捕器内的天牛带回实验室,进行形态学鉴定。共诱集到3个亚科7属7种天牛,其中数量相对较多的是松褐天牛Monochamus alternatus和褐梗天牛Arhopalus rusticus。第一次诱捕到松褐天牛是在6月8日,共诱捕到16头,最后一次诱捕到松褐天牛在10月5日,仅诱捕到1头,7月27日是羽化高峰期,共诱捕到151头;第一次诱捕到褐梗天牛是在5月25日,共诱捕到25头,最后一次诱捕到褐梗天牛在10月12日,共诱捕到7头,7月20日是羽化高峰期,共诱捕到458头。数量较多的松褐天牛是大连地区松材线虫病媒介昆虫之一,褐梗天牛是否为媒介昆虫有待进一步研究。The species of long-horned beetle in Dalian′s pine wilt disease epidemic area were investigated and studied to further clarify the vector insects of pine wilt disease.From May 2020,traps were hung in 22 small subcompartments in Ganjingzi district of Dalian and collect the long-horned beetle in the trap every 7 days and bring them back to the laboratory for morphological identification.There were 7 species,which belong to 7 genera and 3 subfamilies.Among them,the number of Monochamus alternatus and Arhopalus rusticus are relatively large.The first time M.alternatus was trapped in June 8 th,16 were trapped in total.The last time M.alternatus was trapped in October 5 th,only 1 was trapped.July 27 th was the peak of the emergence,a total of 151 were trapped.The first trapping of the A.rusticus was in May 25 th,25 were trapped in total.The last time A.rusticus were trapped was in October 12 th,and 7 were trapped.July 20 th was the peak of the emergence,458 were trapped in total.M.alternatus is one of vector of pine wood nematode in Dalian,whether A.rusticus is vector insect or not need to be further studied.
