摘要
紫外高压诱杀灯一天能诱杀98333头谷蠹、42头锈赤扁谷盗、684头麦蛾、120头米扁虫和411头书虱。与选筛法比较,它能提前20～90天检查出谷蠹,提前18～34天检查出锈赤扁谷盗,提前66～73天检查出麦蛾。由于它能诱杀越冬代成虫,使它们不能返回粮面产卵,压低了下代的发生量,同时,适时施用仓虫敌控制麦蛾和书虱,有2个试验仓的虫口密度一直被控制在较低水平,实现了全年不熏蒸,其防治费用为1015元,而对照仓为1855元。它是一种理想的新型测报防虫器械。
The Ultraviolet and High-tension Light with the function of trapping and killing insects can kill 98333 Rhizopertha dominica (Fabricius),42 Cryptolestes ferrugineus (Stephens),684 Sitotroga cerealella (Olivier),120 Ahasverus advena (Waltl),411 Liposcelis entomophila (Enderlein) daily.Compared with grain screening,Rhizopertha dominica (Fabricius),Cryptolestes ferrugineus (Stephens),Sitotroga cerealella (Olivier) can be detected 20～90,18～34,66～73 days in advance respectively by the new method.Because the light can trap the adults that live through the winter,the light prevents the insects from returning and ovipositing on the surface of stored grain,and depresses the magnitude of offspring.At the same time,because of rational use Cangchongdi to control the Sitotroga cerealella (Olivier) and Liposcelis entomophila (Enderlein),the density of insects in two trial warehouses was kept in a low level.The new method realized non-fumigation all the year round.It costs 1015 yuan in contrast with 1855 yuan for insect control.The light is a perfect and new pattern for controlling insects instrument.
