春尺蠖羽化发蛾特性研究表明 ,发蛾期与气温密切相关。邻近城区比郊外大田发蛾期早 7~ 10d ;发蛾前期雄蛾多于雌蛾 ,以后雌蛾增多 ;成虫为全日程羽化出土 ,雌雄性比为 1∶1.4 2 ;雌蛾交尾最多可达 3次 ,雄蛾仅 1次。应用佳多频振式杀虫灯诱捕春尺蠖雄蛾数量大。灯距 12 0m范围内 ,树干表皮单位面积上的有效卵率较无灯对照区下降了 2 4 %~ 6 1.5 % ,控害效果显著
Studies on the characteristics of the spring moulting feather hair moth showed that the hair moth period is closely related to the temperature. Adjacent urban areas than the rural field hair moth early 7 ~ 10d; male early moth more than female moths, after the increase in female moths; adult full-term emergence of feather, male to female ratio of 1: 1.42; female moths up to up to 3 times, male moth only 1 times. Application Jiaduo frequency vibration pest-killing lamppost male moth large number. The effective egg percentage per unit area of trunk epidermis decreased by 24% ~ 61.5% compared with that of the control without light, the control effect was significant
