吉林西部桑树主要虫害生物药剂防治试验

Experiment on Biological Insect Pesticide Control of Morus alba in Drought and Cold Area in Western Jilin Province

通过对吉林西部干旱寒冷地区桑树虫害开展生物药剂防治试验。结果表明:使用1.8%阿维菌素乳油防治可使红蜘蛛虫口减退率大大提高,均高于对照,以2 000倍液处理效果最好,虫口减退率达76.32%以上;使用苦烟乳油防治野蚕和桑毛虫也取得较好的效果,以1 800倍液处理最佳,虫口减退率达85.85%以上。

Biopesticide control experiments were conducted on pests damaged Morus albain cold and dry regions of western Jilin Province.Result shows that using 1.8%avermectin emulsifiable concentrate can greatly reduce the reduction rate of population of red spider,2 000 times solution have the optimal effect,the decrease rate of insect population is more than 76.32%;using Sophora·tobacco leaf EC to control wild silkworm mulberry caterpillar also achieve optimal results,adopting 1 800 times liquid can obtain the optimal treatment,the reduction rate of the population is more than 85.85.
