摘要
白蜡窄吉丁Agrilus planipennis Faimaire原分布在东北亚国家,包括俄罗斯远东地区,在原产地由于为害不重而受关注度不高,因此没有被列入世界各国危险性有害生物监测重点名单之中。但自21世纪初其传入美国和加拿大之后,已造成重大灾害,成为迄今为止北美地区危害性最大和造成经济损失最为严重的外来入侵森林害虫。由于该害虫的高度隐蔽性,在传入地的早期检测非常困难,发现该虫的地点往往其种群已经定殖多年,因此根除策略难以奏效。美国在白蜡窄吉丁入侵初期进行的根除策略失败后迅速启动了生物防治计划。通过国际合作研究,美国从中国引进了3种寄生性天敌:白蜡吉丁柄腹茧蜂Spathius agrili Yang、白蜡吉丁啮小蜂Tetrastichus planipennisi Yang和白蜡吉丁卵跳小蜂Oobius agrili Zhang&Huang,经大量人工繁殖后在林间进行了释放,现已在当地成功建立了天敌种群,开始发挥越来越重要的控制作用。本文对最近10多年来白蜡窄吉丁生物防治方面的研究进展进行了回顾和简要综述,希望对我国同类蛀干害虫的研究工作有所启示。
The emerald ash borer, Agrilus planipennis Fairmaire（Coleoptera： Buprestidae）, is native to northeast Asian countries, including Russian Far East. It has not been paid much attention previously as an unimportant pest in its native range. Thus, it is not on the high-risk watch lists of any country in the world. But it has caused serious damage both to forests and ecological landscapes, as well as huge economic losses since it invaded the USA and Canada at the early 21 st century, and has since then become the most destructive invasive forest insect pest to North America. As a highly concealed wood-boring pest, the early detection is difficult in local habitats. Usually the pest population has established for some years when it is discovered in certain site so that the eradication strategy is almost impossible. A classical biological control program has been implemented immediately in the USA after the confirmation of the emerald ash borer as an exotic species from Asia. Three parasitic insect natural enemies, Spathius agrili Yang（Hymenoptera： Braconidae）, Tetrastichus planipennisi Yang（Hymenoptera： Eulophidae） and Oobius agrili Zhang Huang（Hymenoptera： Encyrtidae）, have been imported into the USA from China, through an international cooperative study. The populations of the three parasitoid species have already established successfully after release in the field in USA, and played increasingly important roles in suppression of the emerald ash borer. In this paper we reviewed the biological control progress of the emerald ash borer in over decade recently in order to provide some useful implications for similar studies in our country.
