| 摘 要： | 采用拌粮法,在自然条件下,用植物粉单剂、植物粉 硅藻土及植物粉 硅藻土 化学农药不同处理对玉米象进行防治效果试验.结果表明,处理15d后,处理3(硅藻土 0.4%天惠虫清 5%双氧威WP)、处理5(硅藻土 驱蚊草粉 95%马拉硫磷EC)、处理6(硅藻土 驱蚊草粉 5%锐劲特EC)对玉米象的防治效果最好,校正死亡率均达到100%,与其他处理差异达到显著和极显著水平;在植物粉与硅藻土的复配剂中,驱蚊草粉 硅藻土的复配剂对玉米象的防治效果较好,校正死亡率为22.88%;在植物粉单剂的处理中,驱蚊草粉的效果较好.试验表明,植物粉 硅藻土 化学农药处理的防治效果远比硅藻土 植物粉处理的防治效果好;硅藻土 植物粉处理的防治效果又比植物粉单剂的防治效果好.

| Abstract: | Control effect of plant dry powder,its mixtures with diatomite,and with diatomite and insecticide against maize weevil(Sitophilus zeamais Motschulsky) in wheat was tested.Under the natural conditions,it was found that the mixture of the diatomite,0.4% enidiadin EC and 5% fenoxycard WP,the mixture of the Spigelia anthelmia dry powder with diatomite,95% malathion EC and the mixture of the Spigelia anthelmia dry powder with diatomite,5% regent EC were much better than any other mixtures after 15 days,and the corrected morality rate of the maize weevil all was 100%.Among the mixtures of the four plant dry powder with diatomite,the Spigelia anthelmia botanical insecticidal powder was much better than the other three,and the corrected morality rate was 22.88%;Among the four dry plant powders,the Spigelia anthelmia dry powder was the best and it was able to keep more longer effeet than the other three.The effectiveness of the mixture of plant dry powder,diatomite and chemical insecticide was much better than utilizing pure plant dry powder or pure chemical insecticide only;the effectiveness of the mixture of plant dry powder and diatomite was much better than utilizing pure plant dry powder only. |
