一九七四年,在红铃虫发生期间,我们用3—5FE 浓度的性引诱剂涂在纸上,置于盛有适量皂粉水的水盆上,盆口略高于棉花,早晨收,傍晚放,每隔三天换一次,预测红铃虫蛾子消长,取得了较好的效果。雄蛾在性引诱剂盆上的消长规律,与预测日黑光灯下蛾子的消长情况基本相吻合。利用性引诱剂蛾峰,测定二、三代红铃虫发蛾高峰,同当前利用第一代虫害花峰预测二代发蛾峰,和利用期距法预测三代蛾峰是一致的。这种方
In 1974, during the occurrence of the red bollworm, we used 3-5FE concentration of sex attractants coated on paper, placed in the amount of soap powder water basin, the basin slightly higher than the cotton, the morning income In the evening, once every three days, the growth and decline of the pink bollworm moth were predicted and a good result was achieved. The law of the growth and decline of male moths in sex attractant basins was basically consistent with the prediction of the growth and decline of moths in daylight and black light. Using the sex attractant moth peak, the second and third generation pink bollworm moth peak was determined, which is consistent with the current prediction of the second generation moth peak by the first generation pest flower peak and the prediction of the third generation moth peak by the period method.
