赤松毛虫(Dendrolimus spcctabilis Buter)(以下简称松毛虫)是危害赤松(Pinus densiflora)、黑松(P.thunbergii)和油松(P.tabulaeformis)的大害虫。省内分布于烟台、临沂、潍坊、青岛及泰安等市(地)的30多个县(市)。每年平均发生面积约16万公顷,吃死松林约5667公顷,造成严重损失。回顾山东省30多年防治松毛虫的历史虽然创造了很多治虫方法,积累了一些经验,但至目前尚不能有效地控制松毛虫灾,有些地区暴发周期越来越短,甚至连年猖獗成灾,这是很值得探讨的问题。
Dendrolimus spcctabilis Buter (hereinafter referred to as Dendrolimus) is a major pest that damages Pinus densiflora, P. thunbergii and P. tabulaeformis. The province is located in Yantai, Linyi, Weifang, Qingdao and Tai’an and other cities (prefectures) of more than 30 counties (cities). The average annual area of about 160,000 hectares, about 5,667 hectares of eaten pine forest, resulting in serious losses. Review of the history of prevention and control of pine caterpillars over the past 30 years in Shandong Province, although a lot of pest control methods have been created and accumulated some experience, so far the effective control of pine caterpillar disaster has not been achieved. In some areas, the outbreak cycle is getting shorter and shorter, It is worth exploring.
