松褐天牛的天敌及其对寄主的控制能力研究

Studies on the natural enemies and biocontrol of Monochamus alternatus Hope(Coleoptera:Cerambycidae)

根据国内外的研究和作者的研究结果,总结和记述了传播松材线虫的媒介昆虫松褐天牛的天敌种类及其控害情况。共有9 7种天敌,其中天敌昆虫4 7种,病原微生物1 7种,捕食性鸟类3 3种。同时对主要天敌种类病原微生物、肿腿蜂、斑头陡盾茧蜂、花绒寄甲、天牛斑叩甲和捕食性鸟类对松褐天牛的控制能力进行了阐述。

The present paper describes the research results on the natural enemies and biocontrol of Monochamus alternatus Hope （Coleoptera： Cerambycidae）, an important vector of pine wood nematode （Bursaphelenchus xylophilus） in China, based on both the literature and our own study. There are totally 97 species of natural enemies, among which 47 are insects, 17 are microorganism pathogens and 33 are predatory birds. Among them four species of insect parasitoids （ Scleroderma guani , S. sichuanensis, Ontsira palliates, Dastarcus helophoroides ） and one species of insect predator （Cryptalaus berus） are superior to the other species and have potential as biological control agents for the cerambycid. Meanwhile, the control capability of the five insect natural enemies mentioned above, the microorganism pathogens and predatory birds that were studied till now are also reviewed.
