| 摘 要： | 通过田间试验表明,棉蚜暴发初期施用10;蚜虱净可湿性粉剂270 g/hm2,防治棉蚜效果可达98.36;,对瓢虫和食蚜蝇影响相应最小.棉蚜暴发盛期,采用10;蚜虱净可湿性粉剂270 g/hm2,药后5 d防效可达79.58;,其速效性较差,造成棉花在药后5～10 d生长势衰败严重;采用35;赛丹乳油900 g/hm2,第5 d防效大于97;,对瓢虫和食蚜蝇有一定影响,但能快速压制蚜虫种群密度,使其量限制于瓢虫和食蚜蝇等天敌可控制的范围.

| Abstract: | The present study was designed to investigate the control effect of the insecticides on cotton aphid in different periods of its occurrence.The field trial was conducted to control cotton aphid.In the initial period of cotton aphid occurrence,the effect of controlling cotton aphid could reach 98.36% by use of imidacloprid 10% wettable powders(WP) 270 g/hm2,but which performed a certain effect on ladybug and syrphid.In the high period of cotton aphid occurrence,the control effect was over 97% after 5 days by using thiodan emulsifiable concentrates(EC) 900 g/hm2 of cotton aphid and could fast control the density of cotton aphid to limit to a number of natural enemies such a ladybug and syrphid. |
