摘要
【目的】评测取食不同寄主植物的桃小食心虫Carposina sasakii飞行能力,为该虫预测预报和防控提供参考。【方法】使用飞行磨装置测定了取食不同寄主植物(海棠、苹果和杏)的桃小食心虫雌雄成虫的飞行能力,比较了取食同一寄主植物的雌雄成虫间和取食不同寄主植物的同一性别个体间平均飞行距离、平均飞行时间、平均飞行速度和最大飞行速度4个飞行参数。【结果】在12 h的飞行测试中,桃小食心虫成虫最长飞行距离为24.54 km,最长飞行时间接近12 h,最大飞行速度为5.88 km/h,飞行11~12 h的个体占比最高(36.98%)。取食同一寄主的雌成虫各飞行参数值均大于雄成虫。取食苹果和海棠的成虫的平均飞行距离在雌雄间存在显著差异,取食苹果的雌成虫的平均飞行距离显著大于取食杏的个体,取食苹果的雌成虫平均飞行速度和最大飞行速度显著大于取食另外两种寄主的个体;但是取食不同寄主植物的雄成虫间各飞行参数值差异不显著。【结论】桃小食心虫成虫飞行能力较强,取食同一寄主植物的雌雄成虫间以及取食不同寄主植物的雌成虫间飞行能力存在差异。
【Aim】To evaluate the flight ability of the peach fruit moth,Carposina sasakii,fed on different host plants,so as to provide basic data for its forecast and management.【Methods】The flight ability of female and male adults of C.sasakii fed on different host plants(crabapple,apple and apricot)was measured by using a flight mill device,and the average flight distance,average flight duration,average flight speed and maximum flight speed were compared between female and male adults fed on the same host plant and among individuals of the same sex fed on different host plants.【Results】The longest flight distance,the longest flight duration and the maximum flight speed of C.sasakii adults within 12-h flight testing were 24.54 km,~12 h and 5.88 km/h,respectively.The highest proportion of individuals(36.98%)had a flight duration ranging between 11 and 12 h.The values of various flight parameters were higher in female adults than in male adults fed on the same host plant.There was significant difference in the average flight distance between female and male adults fed on apple and crabapple,and the average flight distance of female adults fed on apple was significuntly longer than that fed on apricot.The average flight speed and the maximum flight speed of female adults fed on apple were significantly higher than those fed on the other two hosts.However,the values of various flight parameters of male adults fed on different host plants showed no significant difference.【Conclusion】C.sasakii adults have a relatively strong flight ability,and exhibit different flight abilities between female and males fed on the same host plant and among female individuals fed on different host plants.
