白蜡窄吉丁成虫植物源引诱剂与粘虫板的筛选及发生动态分析

【目的】筛选出白蜡窄吉丁Agrilus planipennis Fairmaire成虫的敏感粘虫板、植物挥发物引诱剂及粘虫板引诱剂组合诱捕器,为有效监测白蜡窄吉丁种群动态及成虫诱杀提供科学依据。【方法】在白蜡树上悬挂4种颜色粘虫板和3种植物源挥发物引诱剂及其组合诱捕器,并每日记录其成虫诱捕数量。【结果】浅绿色粘虫板总诱捕数量为最多,3块样地总诱捕量为55头,2 d平均诱捕量为2.03头/张,其次是黄色粘虫板,其总诱捕数量为30头,2 d平均诱捕量为1.11头/张;不同引诱剂对白蜡窄吉丁的总诱捕数量最多的为EtOH,总诱捕数量为62头,2 d平均诱捕量为1.72头/张,其次是FZC,总诱捕量为51头,2 d平均诱捕量为1.42头/张;4种粘虫板和3种引诱器组合中浅绿色粘虫板和EtOH引诱剂组合诱捕器相比其它组合引诱效果最好,总诱捕量为28头,30日内金黄色粘虫板和EA组合引诱效果最差,3块样地中诱捕数量均为0头。【结论】白蜡窄吉丁对浅绿色粘虫板具有较好的趋向性。浅绿色粘虫板与EtOH组合,可用于白蜡窄吉丁成虫数量动态监测。

Screening of Plant-Derived Attractants and Clayworm Plates for Ash Borer Adults and Their Development Dynamics

【Objective】 To screen out the unique sticky trap and botanical attractant of EAB in the hope of providing of a scientific basis for monitoring the population emerald ash borer (EAB) and environment friendly management method of the pest.Agrilus planipennis Fairmaire【Methods】 The effects of 4 different colors of sticky traps and 3 species of botanical attractant were determined by orthogonal component.【Results】 The number of EAB adults attracted by light green traps was the most, the total trapping pest number of 3 plots was 55, the average trapping number of 2 d was 2.03 head / sheet, followed by the egg yellow sticky trap, whose average trapping was 1.11 and 30 in total.The effect of different botanical attractant showed that the most attractive attractant was EtOH(a) with an average of 1.72 in 2-days and 55 in total, and the secondary effective attractant was Iinalool(b) with an average of 1.42 in 2-days and 51 in total.Of the four viscworm plates and three attractants, the light green sticky traps and EtOH attractant combination traps outperformed the others with 28 adults attracted in 30 days.Within 30 days, the combination of golden sticky worm plate and EA had the worst lure effect, and the number of trapping was 0 in all three plots.【Conclusion】 Light- green sticky traps was the most attractive color of EAB adult and EtOH(a) has a attracting effect of the pest.The combination of light-green sticky trap and EtOH(a) can be used as a monitoring method of EAB.
