| 中文摘要: |
| 二点委夜蛾是夏玉米区新发生的一种害虫。由于没有行之有效的防治方法，而使其扩展迅速，为害渐趋加重，对夏玉米生产构成严重威胁。为了探索二点委夜蛾的有效防治方法，本试验通过不同化学防治方法对二点委夜蛾的防效进行研究，结果显示：9种供试药剂在二点委夜蛾2龄期进行田间喷雾试验总体防治效果较好，其中50%辛硫磷乳油防治效果高达95.03%，明显高于其他药剂；采取不同的施药方法研究表明，选用有效农药喷雾或配成毒饵、毒土顺垄撒施均有较好的防治效果，其中毒饵、毒土效果最好，而顺垄喷淋灌根防治效果最差，仅为30.10%。 |
| 英文摘要: |
| Athetis lepigone is a new pest occurring in summer corn production areas. Since there have been no effective control methods, it expanded rapidly, threaten summer corn production seriously, and its damage increased gradually. In order to explore effective control methods, we studied the chemical control methods. The results showed that the overall control effects of 9 insecticides field sprays were better before the second-instars of A. lepigone. One of them was 50% phoxim emulsifiable concentrate, with a control effect of as high as 95.03%, obviously higher than other pesticides. The study of taking different pesticide application methods showed that good control effects could be achieved by spraying effective pesticides or spreading poison baits or pesticide clay mixtures along ridge. Among them, the effects of poison bait or pesticide-clay mixture were best. The effect of spray root irrigation along ridge was the worst, with a control effect of only 30.10%. |
