摘　　要：在高大平房仓、浅圆仓中,施用5%甲基嘧啶硫磷粉剂防治书虱。20d后,虫口减退率分别为72.77%、80.34%,虽比3%书虱灵微粒剂的83.54%略低,但显著高于不施药剂的对照仓。对照仓由药前的442头/kg上升至药后的8480头/kg,约增加了19倍。5%甲基嘧啶硫磷粉剂不仅能有效地防治书虱,而且也能抑制锈赤扁谷盗、谷蠹、麦蛾等害虫。应用储粮防护剂会略微增加防虫费用,但防虫效果更好。By applying powder of 5% pirimiphos-methyl in a large warehouse and a squat silo,the rate of population reduction of book louse were 72.77% and 80.34% respectively after 20 days.The effect was slightly lower than 3% micro-granules of Shu-Shi-Ling,but it was obviously better than the control group,the population density increased by about 19 times（i.e.from 442 heads per kilogram to 8480 heads per kilogram）.The results showed that 5% pirimiphos-methyl can not only prevent and control the book louse,but also restrain such insects as Cryptolestes ferrugineus （Stephens）,Rhyzopertha dominica （Fabricius） and Sitotroga cerealella Oliver,etc.The effect of prevention and control by applying grain protectant would be much better,but the expense would increase slightly.
