摘　　要：通过2005—2006年在河南省中牟县黄河滩区利用生物农药、植物源农药和常用化学农药防治东亚飞蝗的田间笼罩试验结果表明:30%杀蝗绿僵菌油悬浮剂167ml/hm2、250ml/hm2,药后14d的平均防效可达到90%左右,1%苦皮藤素乳油300ml/hm2、0.3%苦参碱水剂900ml/hm2两个处理的平均防效均达到90%以上,与中毒化学农药氟虫腈的防效接近,而优于低毒化学农药马拉硫磷的防效。鉴于杀蝗绿僵菌、苦皮藤素、苦参碱三种药剂均为低毒的生物农药和植物源农药,可作为替代有机磷和菊酯类农药用于东亚飞蝗的防治。The effect of the biocide, the pesticide stemming from botany and the chemical pesticide most in use which specialize in eliminating ＂Locusta migratoria manilensis Meyen ＂shrouding the fields in Yellow- River beach area Zhongmou County Henan Province were tested in 2005 and 2006. The result clearly indicates： Using 30% of Metsrhizium Anisipliae LUV to eliminate locusts with capacity of 167-250ml/hm^2, the average elimination rate is about 90% 14 days later. Using 0.3% of Matrine with capacity of 900ml/hm^2 and 1% of Celangulins with capacity of 300 ml/hm^2, the average elimination rate of the two eliminating locusts is higher than 90%. Compared with middle-poison Fipronil and low-poison Malathin, the result of effects is very close to the former and better than latter. Since Metarhizium, Matrine, Celangulins all belong to low-poison biocide and low-poison pesticide stemming from botany, we can use them as a substitute for organic phosphorus pesticide and cycloprothrin pesticide.
