采用拌粮法 ,用硅藻土单剂、配方 1 (硅藻土 +95 %马拉硫磷EC)、配方 2 (硅藻土 +2 . 5 %溴氰菊酯EC)、配方 3 (硅藻土 +80 %敌敌畏EC)、配方 4(硅藻土 +0 . 4%天惠虫清EC)、配方 5 (硅藻土 +5 %双氧威WP)、配方 6(硅藻土 +5 %抑太保EC)对嗜卷书虱Liposcelisbostrychophila进行防治研究 ,结果表明 :配方 4为优选配方 ,处理 2 4h后 ,3种浓度的致死率均达到 1 0 0 % ;配方 1、配方 2、配方 3、配方 5、配方 6对嗜卷书虱的致死率处理 48h后达到 1 0 0 % ;单用硅藻土处理 96h后达到 1 0 0 % ,各配方处理间差异极显著。
5% deltamethrin EC), Formulation 3 (silicon dihydrate 4% diatomaceous earth clear EC), formula 5 (diatomaceous earth + 5% dioxygen WP), formula 6 (diatomaceous earth +5% % Inhibitory effects of EC on Liposcelis bostrychophila control study, the results showed that: Formulation 4 is the preferred formula, after 24 hours of treatment, the three kinds of concentrations were 100% lethality; Formulation 1, Formulation 2, Formulation 3 , Formula 5 and Formula 6, respectively, reached 100% after 48h treatment, and 100% after treated with diatomaceous earth for 96h. There was significant difference among the treatments.
