异色瓢虫规模化生产技术及瓢虫工厂的建立

Mass rearing the multicolored Asian lady beetle on beet armyworm larvae

异色瓢虫Harmonia axyridis(Pallas)是一种重要的捕食性天敌,工厂化人工饲养异色瓢虫是利用其进行蚜虫等小型害虫生物防治的有效手段。本文报道了在河南省济源白云实业有限公司建立的基于甜菜夜蛾Spodoptera exigua(Hübner)低龄幼虫的工厂化生产的技术流程。利用这一技术,可以大量、稳定地生产异色瓢虫各虫态个体,基本实现了异色瓢虫的工厂化生产。文中还探讨了异色瓢虫产业化进程中存在的问题,期望瓢虫天敌产业化和商业化能够有所突破。

The multicolored Asian lady beetle Harmonia axyridis （Pallas） is an important natural enemy of many Hemipteran, Lepidopteran and Coleopteran insect pests. Mass rearing and industrialization of this species for field release as part of IPM programs is a promising way to control aphid infestations. A pilot facility to produce these beetles on an industrial scale by feeding them exclusively on larvae of the beet armyworm Spodoptera exigua （Htibner） has been established at the Henan Jiyuan Baiyun Industry Co. , Ltd. , the Pilot-Scale Base of Bio-pesticides, Institute of Zoology, Chinese Academy of Sciences, in Henan Province. We here describe the methods used to rear lady beetles at this facility and discuss the problems and obstacles that need overcoming in order to improve the production and commercialization of lady beetles as biocontrol agents.
