利用性诱剂诱杀江苏沿海地区三、四代棉铃虫的试验、示范结果表明 ,每 0 .1 3 4公顷棉田放置 1个诱芯盆的诱蛾效果较好且经济 ,与相同面积棉田内插放 40个树枝把的诱蛾效应比较 ,前者所诱雄蛾量增加 3 6.3 1 %～ 45 .5 9% ,雌蛾交配率下降 3 5 .64 %～ 44 .75 % ,田间落卵量降低 9.90 %～ 1 5 .0 5 % ,幼虫量减少 7.69%～ 1 2 .3 6% ,蕾铃被害量下降 4.49%。室内的性比试验证实 ,棉铃虫雌蛾的产卵量与群体中雌蛾的性比比例呈负相关 The experiment of trapping the third and fourth generations of cotton bollworm in the coastal area of ​​Jiangsu Province by using sex attractant showed that the moths with one induced core per 0.134 hectare of cotton field were better and more economical than the cotton fields with the same area Put 40 branches of the lure effect compared to the former induced male moth increased by 3 6.31% ~ 45.59%, the female moth mating rate decreased 35.64% ~ 44 .75%, the amount of field eggs decreased 9.90% ~ 15.05%, the amount of larvae decreased by 7.69% ~ 12.36%, the amount of buds of buds decreased by 4.49%. The indoor sex ratio test confirmed that the fecundity of H. armigera was negatively correlated with the sex ratio of female moths
