秸秆还田与药剂处理对夏玉米田二点委夜蛾发生数量的影响
Effects of Straw Returning and Chemical Control on Number of Athetis lepigone Moschler in Summer Maize Fields
摘要
Abstract
Athetis lepigone Moschler is a new kind of insect pest occurring in summer com 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.关键词
