文档介绍：美国白蛾综合防治技术研究II 菌素乳油、甲维盐乳油2种处理1天就可达到处理防效100%,灭幼脲Ⅲ号发挥效果慢。防治3龄虫以上就需要增加3种药剂浓度,%超级阿维菌素乳油和甲维盐乳油效果较灭幼脲Ⅲ号见效快。5、美国白蛾核型多角体病毒(HcNPV)防治试验与应用研究。研究表明核型多角体病毒(HcNPV)最佳防治时期为2~3龄虫。×107PIB/ML。×107PIB/ML和苏云金杆菌1×104IU/ML的混合药剂防治美国白蛾比单纯用病毒进行防治效果好。6、白蛾周氏啮小蜂(Chouioia cunea)防治美国白蛾的推广应用研究。试验表明,利用周氏啮小蜂防治第2代美国白蛾较第1代效果更好,白蛾周氏啮小蜂能对东营地区美国白蛾起到很好的防控作用。关键词:美国白蛾;防治;技术;研究山东农业大学硕士专业学位论文III Abstract Hyphantria cunea is a species of world-wide quarantine order to more effectively prevent and control it, a investigation and control test by chemical and biological means was made in Dongying district. Made the following preliminary results. characteristics of Hyphantria cunea. characteristics of emergence and life history of Hyphantria cunea was systematic surveyed and found that fall webworm occurs three generations each year in Dongying area, two full generations, part of the 3rd generation. The generation of the instars interchangeably, irregular development, the first 2, 3 on behalf of the generations overlap. Summarized the life cycle of Hyphantria cunea in the Dongying cunea hazard tree tree species wew damaged by Hyphantria cunea in the Dongying area, of them mulberry, ash, locust, poplar, willow (Salix babylonica L.) 5 species is seriously damaged. but Hyphantria cunea didn’t feed off Neem tree, cypress (Juniperus chinensis cv. Kaizuka), Ligustrum (Ligustrun lucidum Ait), etc. cunea predators of Hyphantria cunea few natural enemies in the Dongying area, natural control in the fall webworm play a smaller role, can not effectively control Hyphantria cunea. Dongying District survey found that natural enemies of Hyphantria cunea larvae only Dolichogenid singularis, pupal stage 4 species , Chouioin cunra, Tetrastichus septentrionalis,mimns disparis, Exoristar species of predatory insects( Chrysoperla sinica Tjeder) and1 species of parasitic fungi ( Bcuweria bassiana). Among them, Cho
