This paper introduced that under the conditions of 55%,60%,65%,70% and 75%RH,25±1℃,the efficacy of diatomaceous earth Protect-It TM at different dosages of 0.1,0.3,0.7,1.0,3.0 and 5.0g/m 2 against adults of Liposcelis entomophila.The results indicated during 7~14 days the mortality of L.entomophila adults increased with the relative humidity decrease and the dosages increase,and the exposure time prolong.The mortality of treatment groups was 100% within 4~14 days but 6.7%~48% for controls within...

This paper introduced that under the conditions of 55%,60%,65%,70% and 75%RH,25±1℃,the efficacy of diatomaceous earth Protect-It TM at different dosages of 0.1,0.3,0.7,1.0,3.0 and 5.0g/m 2 against adults of Liposcelis entomophila.The results indicated during 7~14 days the mortality of L.entomophila adults increased with the relative humidity decrease and the dosages increase,and the exposure time prolong.The mortality of treatment groups was 100% within 4~14 days but 6.7%~48% for controls within 7~14 days.Therefore,when Protect-It TM applied to the surface of empty grain bin,the space of the bin,and top and botton layer of the grain mass,L.entomophila and other stored grain insects were controlled very well.

本文介绍了在 2 5± 1℃条件下 ,不同湿度 (5 5 %、60 %、65 %、70 %和 75 %RH)对硅藻土杀虫剂Protect-ItTM不同处理剂量 (0 .1、0 .3、0 .7、1.0、3.0和 5 .0g/m2 )致死嗜虫书虱成虫效果的影响。结果表明 ,处理 7~ 14天 ,嗜虫书虱成虫的死亡率随着Protect-ItTM环境相对湿度的减少、施用剂量的增加和处理时间的延长而增加 ,分别在 4~ 14天达到 10 0 %死亡率。因此 ,Protect -ItTM用于粮仓的空仓处理、实仓的空间结构处理和粮堆表层或底层处理时 ,对嗜虫书虱有较好的防治作用。

mg/kg diatomaceous earth protect-it TM was used to control stored-grain insects in wheat in the lab.The results showed that it can kill all the tested adult insects,it has the same effect as 8mg/kg FEN.The Tribolium Castaneum (H.) were well controlled,and it can also control Rhyzopertha dominica (F.)and Sitophilus zeamais (M.).The results in model bin showed that the effect of diatomaceous earth protect-it TM in paddy was better than in wheat,and the effect can last a long time.

在实验室内用 5 0 0mg/kg的Protect -ItTM 处理小麦 ,几乎可以杀灭所有试虫的成虫 ,与 80mg/kg杀螟松处理效果相似 ,并能有效抑制赤拟谷盗的发展 ,对玉米象和谷蠹也有一定的抑制作用。从实仓试验结果来看 ,其在稻谷中使用效果优于小麦 ,同时实仓的生物测试结果表明Protect -ItTM有很好的持效作用。

It tells about the tingling and creepage in one - way circuit equipment and analyses the cause of electrified outer covering (faradism、creepage) ,the difference of their normal and abnormal electrification,and ways to remove electrification in outer covering (meet cipher protect、earth protect).

介绍了单相用电设备的麻电和漏电现象,分析设备外壳带电的原因(两种情况:感应电,漏电),外壳正常带电和非正常带电的区别,以及消除外壳带电的措施和方法(接零保护,接地保护)。
