用大区对比法，对ＰＢ－ＲＯＰＥＬ防治棉红铃虫及棉铃虫效果进行了示范试验研究。结果表明，ＰＢ－ＲＯＰＥＬ对棉红铃虫干扰效果极好，干扰率为９９％ ～１００％ ，同时对棉花害虫天敌有明显的保护作用，天敌增加１．３０～９．２３倍，控制棉红铃虫虫害花效果为７６％ ～１００％ ，对棉红铃虫青铃危害控制效果为５８．５２％ ～８４．２５％ ，单铃虫道（瘤）控制效果为６８．５４％ ～８７．５０％ 。
Using the method of large area comparison, the effect of PB-ROPEL on cotton bollworm and cotton bollworm was tested. The results showed that PB-ROPEL had an excellent interference effect on H. armigera, with the interference rate of 99% -100%. At the same time, it had obvious protective effect on natural enemies of cotton pests and the natural enemies increased by 1.30-9.23 times. The control effect of bollworm infestation was 76% ~ 100%, the control effect of bollworm bollworm was 58.52% ~ 84.25%, and the control efficiency of bollworm (tumor) was 68.54% ~ 87. 50%.
