【摘要】 1997年在南疆棉区 3个地点研究了性信息素、黑光灯和杨树枝把对棉铃虫成虫的诱捕效果。试验结果表明 ,性信息素笼罩诱捕器的诱蛾量分别是黑光灯和杨枝把的 9 5和 2 5 4倍 ,性信息素水盆诱捕器的诱蛾量是杨枝把的 1 4 4倍。经统计分析 ,以上倍数随发蛾量的增大有上升趋势 ,即在发蛾量大时性信息素的诱捕效果进一步提高。考虑到笼罩诱捕器的高效、稳定和简易 ,作者希望在我国尽快将其用于进行棉铃虫成虫的标准化监测。更多还原

【Abstract】 A study was carried out for monitoring numbers of moths of the cotton bollworm, Helicoverpa armigera (Hübner),using pheromone,blacklight and poplar twig bunch traps at 3 locations in southern Xinjiang,China in 1997.The results showed that the number of catches in cone traps (80 cm×50 cm) baited with pheromone was 9.5 and 25.4 times those in blacklight and poplar twig traps,respectively,and catches in water tray traps (28 cm×10 cm) was 14.4 times that in poplar traps.By statistical analysis,it was found that the relative efficiency of pheromone traps tended to increase with the amount of occurrence.Considering its catching efficiency,stability and feasibility, the authors suggested to utilize an improved cone trap in monitoring program for the bollworm.更多还原
