摘要：全能杀虫平台是湖北百米生物实业有限公司开发的生物防控系统，该系统通过平台诱蛾、寄生蜂寄生害虫卵及寄生蜂携带专性昆虫病毒定向感染害虫卵，依据卵面传毒原理实现幼虫染病流行的三位一体技术控制虫害的发生。2015年全能杀虫平台在湖北省咸宁地区茶园进行防治茶毛虫（Euproctis pseudoconspersa Strand）的示范，开创性地解决了利用生物技术防控茶园茶毛虫的技术难题，示范茶园平台诱蛾效果显著，卵块寄生率高达80.0%，卵粒寄生率达36.0%，病毒流行造成幼虫虫口减退率达58.6%，防控后虫口密度低至50～240头/hm2；示范区茶园茶叶产量相比化防区茶园无显著差异。

Abstract： Almighty insecticidal platform is a biological control system developed by Hubei Baimi Bio-industrial Co. Ltd， which can achieve oriented infection of pest eggs through the platform trapping moth， pest eggs parasitism and obligate insect virus carrier of parasitic wasp. Based on the virus transmission principle of eggs surface， the platform can realize the larvae infected popular three-in-one technology and control of pest occurrence. In 2015， the demonstration control of Euproctis pseudoconspersa Strand by almighty insecticidal platform in Hubei Xianning tea garden showed that the platform creatively solved the prevention and control problem of tea garden Euproctis pseudoconspersa Strand by biological technology. The moth trapping effect in demonstration tea garden was significant， the egg-masses parasitic rate was as high as 80.0%， the eggs parasitic rate was 36.0%， and the larvae reduction rate caused by virus epidemic was 58.6%. After the prevention and control， the insect density was as low as 50-240 insects per hectare. There was no significant difference in tea production between the demonstration and chemical control tea garden.

茶毛蟲（Euproctis pseudoconspersa Strand）是茶园中食叶性一类害虫，发生比较普遍。茶毛虫行群集生活，密度大时，常造成茶丛秃顶而导致茶叶减产，茶毛虫幼虫体表密布毒毛，且毒毛会随风飘散，接触皮肤后奇痒难忍，大龄幼虫期常常就是采茶期，严重影响除草、采茶等农事操作。适于药剂防治的低龄幼虫期生活在茶丛中下层，虫体隐蔽，致使防治效果不理想。

全能杀虫平台包括生物杀虫平台和毒·蜂杀虫卡（以下简称“生物导弹”）两个应用产品，一是通过生物杀虫平台配合茶毛虫性诱芯诱集大量雄性成虫，减少雌雄成虫交配机率来降低雌性成虫在寄主作物上的落卵量，达到减少幼虫虫口密度的目的；二是通过生物导弹寄生蜂直接寄生害虫卵来达到消灭害虫卵，从而减少幼虫虫口密度的目的；……
