中文摘要:
【目的】 通过比较不同药剂防治大豆蚜Aphis glycines的效果,筛选出适宜使用的生物农药,为生产上防治大豆蚜提供科学依据。【方法】 选用室内毒力和田间药效试验相结合的方法,测定了10种杀虫剂对大豆蚜的防治效果。【结果】 室内毒力测定结果显示,各药剂经24 h处理的试虫校正死亡率在85.84%~100%之间。田间药效试验结果表明,除2.5%多杀霉素悬浮剂外,其它药剂均表现出对于大豆蚜的较好的防治效果。15%除虫菊素水乳剂、6%乙基多杀菌素悬浮剂、3%阿维菌素水乳剂、0.5%苦参碱水乳剂这4种生物农药施用后的4 d防治效果均在95%以上。【结论】 这4种生物农药具有较高的推广价值,可用于大豆蚜的防治。
英文摘要: [Objectives] To provide a scientific basis for selecting pesticides to control the soybean aphid, Aphis glycines (Hemiptera: Aphididae). [Methods] The effectiveness of ten insecticides on A. glycines was tested in the laboratory and in the field. [Results] The results of laboratory toxicity experiments show that corrected mortality ranged from 85.84% to 100% after 24h. The results of field trials show that only one of the insecticides tested, spinosad 2.5% SC, was ineffective in controlling A. glycines. The corrected control effects of pyrethrin 15% EW, spinetoram 6% SC, abamectin 3% EW and matrine 0.5% EW were > 95% after 4 d. [Conclusion] These four biopesticides are broadly popular and can be an effective means of controlling A. glycines.
