摘要
加拿大杨树枝把田间诱蛾试验 ,单把日平均诱蛾 4.1 7头 ,雌性比为 1 .72 ;在加拿大杨树枝把中加入棉铃虫性诱剂诱芯后 ,单把日平均诱蛾 5.5头 ,雌性比为 1 .86。鲜加拿大杨树叶粗提物对棉铃虫刚羽化处女雌蛾引诱效果为 2 6.67% ;经过堆放 2天的杨树叶粗提物对棉铃虫刚羽化的处女雌蛾引诱效果为 44.44%。
In this paper , the attracted effects on moths of Helicoverpa armigera were reported in the field and lab. The results showed that, 4.17 moths of Helicoverpa armigera were attracted by the Populus canadensis Moench per branches every day.The ratio of female and male attracted was 1.72.While the synthetic sex pheromones added in branches,5.5 moths were attracted,and the ratio was 1.86.The attracted efficiency of substances extracted from fresh leaves on female and not mated Helicoverpa armigera moths was 26.67%,while the attracted efficiency of substances extracted from leaves piled for two days was 44.44%.
