1974年在红铃虫发生期间,我们用3—5头雌蛾腹部制成性引诱剂,把它涂在纸上,置于水盆上,盆内保持适量皂粉水,盆口略高于棉花,早晨收,傍晚放,每隔3天换一次,预测红铃虫蛾子消长,取得了良好的效果。对红铃虫蛾发生期间的观察表明,雄蛾在性引诱剂盆上的消长规律,一般能反映客观实际情况,与预测日灯下蛾子消长情况基本相吻合。当前均用第一代虫害花峰来预测第二代发蛾峰。如棉田虫害花峰于7
In 1974 during the occurrence of the red bollworm, we use the first 3-5 female moth abdominal sex attractant, it is coated on paper, placed in the basin, the basin to maintain the amount of soap powder water, basin slightly higher than Cotton, morning harvest, put in the evening, every 3 days for a second forecast moths pink bollworm growth and achieved good results. Observations on the occurrence of the pink bollworm moth showed that the law of the growth and decline of male moths in the sex attractant pot generally reflected the actual situation and was in good agreement with the prediction of the growth and decline of moths under daylight. The first generation of pest flower peaks are currently used to predict the second generation of hair moth peaks. Such as cotton pest flower peak at 7
