【摘要】 红棕象甲Rhynchophorus ferrugineus Oliver是世界著名的严重危害棕榈植物的毁灭性入侵害虫,现已传入我国长江以南广大地区,对我国棕榈植物的安全生产造成严重威胁。本文比较了聚集信息素来源、诱捕器设置高度、颜色和类型对红棕象甲成虫诱捕效果的影响。结果表明:2种不同来源的红棕象甲聚集信息素诱捕效果无显著差异;诱捕器置于地面诱捕效果最好;红色和黑色诱捕器的诱虫量显著优于白色和黄色诱捕器;诱捕器类型对诱虫量无显著影响。本研究结果可为红棕象甲聚集信息素的监测技术提供指导。更多还原

【Abstract】 Red palm weevil Rhynchophorus ferrugineus Oliver,a concealed tissue borer,is a lethal invasive pest of palms and is reported to invadthe south of the Yangtze river in China,and poses a serious threat to China’s palm industry. The study was conducted to determine the effects of lure source,trapping height,trap color and trap shape on the capture efficacy for R. ferrugineus. Results showed that R.ferrugineus trapped by 2 sources of aggregation pheromone was similar. The optimum height of the trap was on the ground. The capture efficacy of red and black traps were significantly higher than that of white and yellow traps. The differences of the quantity of the adults by 3 types of trap were not significant. The present results could be used in better monitoring R. ferrugineus by using its aggregation pheromone.更多还原
