| 摘 要： | 比较了加拿大杨(Populuscanadensis)枝把、棉铃虫性诱剂、高压汞灯在田间对棉铃虫(Helicoverpaarmigera)的引诱效果。结果表明,加拿大杨枝把在田间以诱集棉铃虫雌蛾为主,所诱棉铃虫雌、雄性比为1.61。加拿大杨枝把日诱雄蛾量与日诱雌蛾量呈显著正相关,与性诱剂日诱雄蛾量、高压汞灯日诱雄蛾量相关性不显著。每日棉铃虫百株落卵量与加拿大杨枝把、高压汞灯日诱蛾量呈显著正相关,与性诱剂日诱蛾量无显著相关性。讨论了加拿大杨枝把在田间引诱棉铃虫的机理。

Trapping Effects of Populus canadensis Bundles on Helicoverpa armigera in Field |
| |
| Abstract: | The trapping effects of Populus canadensis bundles, sex pheromone attractant and high-pressure mercury light on cotton bollworm (Helicoverpa armigera) in the field were observed. The bundles mainly trapped females with a sex ratio of the moth as 1.61. The daily number of trapped males was correlative with tha t of trapped females in the bundles. However, the daily number of males captured by the bundles was not correlative with that of males captured by sex pheromone attractant and light. The number of eggs per 100 cotton plants was correlative with that of mot hs trapped by the bundles and light respectively, but not with the number of males captured by se x pheromone attractant. Mechanism of attraction of the bundles for the moths was discussed. |
