【摘要】 1997年在南疆棉区研究了性信息素笼罩诱捕器和水盆诱捕器对棉铃虫的诱捕效率。试验结果表明 ,伽师县 2乡和铁日木乡两地笼罩诱捕器的诱蛾量分别是水盆诱捕器的 18 6倍和 11 9倍。经统计分析 ,诱蛾量随季节推移有下降趋势。根据笼罩诱蛾效果及其相对稳定性 ,作者希望在我国尽快用笼罩诱捕器取代水盆诱捕器进行棉铃虫成虫的标准化监测。更多还原

【Abstract】 A comparative test of male catches of the cotton bollworm, Helicoverpa armigera (Hübner), by cone (80 cm×50 cm) and water tray (23 cm×8 cm) traps baited with synthetic sex pheromone was made in South Xinjiang, China in 1997. The results showed that male catches per trap and per night by cone traps were 18.6 and 11.9 times as that by water tray traps at two observed locations, the No.2 Town and Tierimu Town in Jiashi County, respectively. Statistical analysis indicated that male catches by cone traps decreased with seasons. For their higher efficiency, stability and feasibility, the authors suggest, the cone traps be improved to replace the water tray traps for standardized monitoring program of adult cotton bollworms in China.更多还原
