烟蚜茧蜂规模化繁殖和释放技术研究

Mass rearing and releasing of Aphidius gifuensis(Ashmead)

烟蚜(桃蚜)Myzus persicaeSulzer是危害云南省烟草Nicotina tobaccumL.的一种主要害虫.生产中还是以杀虫剂为主控制该虫危害.然而,近年来地方政府、科技人员和农户都在寻求以生物防治的方法控制烟蚜危害.烟蚜茧蜂是自然界控制烟蚜的一种优势天敌.作者在云南省玉溪烟区经过5 a的研究和推广,形成的烟蚜茧蜂(Aphidius gifuensisAshmead)大规模繁殖和释放技术.对大量繁蜂的设备和成本核算以及相关的一些技术问题进行了一定的探讨.

The green peach aphid,Myzus persicae,is a major pest of tobacco,Nicotiana tabacum,in Yunnan province,China,where its control still depends on the use of insecticides.In recent years,the local government and farmers have sought toimprove the biological control of this tobacco pest.In this paper,we present methods for mass rearing Aphidius gifuensis,a dominant endoparasitoid of M.persicae on tobacco plants in this region.The tobacco cultivar K326(N.tabacum) was used as the host plant and M.persicae as the hos...
