| 摘 要： | 二点委夜蛾(Athetis lepigone Moschler)是夏玉米产区一种新发生的害虫。调查发现,秸秆还田地块尤为严重。本试验对秸秆还田与药剂处理地块的二点委夜蛾的危害情况进行了调查。结果表明,秸秆还田未进行药剂处理的地块被害株率达到82%,百株虫量最大为88头,喷除草剂和杀虫剂后二点委夜蛾发生量及危害率与未喷的差异不显著,百株虫量略有降低,但无秸秆还田地块喷施除草剂与杀虫剂后,其危害率显著低于上述处理,被害株率为20%,百株虫量为6头。 |

| Abstract: | Athetis lepigone Moschler is a new kind of insect pest occurring in summer corn production areas.By investigation,it was found especially serious in straw returning fields.In this paper,its damage status was investigated in straw returning and chemical controlled fields respectively.The results showed that the rate of damaged plants was 82% and the highest pest number per 100 plants was 88 in the straw returning fields without chemical control.The application of herbicides and pesticides had no significant effects on the occurrence amount and damage rate and decreased the pest number per 100 plants a little compared to no chemical control.But in the summer maize fields without straw returning,the application of herbicides and pesticides could significantly decrease the damage of Athetis lepigone with the rate of damaged plants as 20% and the pest number per 100 plants as 6. |
