摘　　要：通过调查枫香刺小蠹侵害30年生北美枫香的危害特点和发生规律,并对其进行初步防治探究,以期为该小蠹后续防治与研究工作提供参考。通过对常熟市虞山北路两侧主要景观树种——北美枫香的小蠹虫危害情况开展详细调查,对枫香刺小蠹在30年生北美枫香上的危害特点形成了新的认识,建立了北美枫香受害等级分类方法并计算出调查地的蠹害指数,提出了一些初步的物理及化学防治建议并对防治效果做初步评价。调查结果表明:虞山北路枫香刺小蠹危害严重,蠹害指数达到46.6;小蠹对30年生北美枫香危害模式与苗圃地10年生北美枫香存在较大不同,且相较于本土枫香,小蠹更倾向于侵害北美枫香;经过防治后树木受害率降幅超过80%。枫香刺小蠹对不同树龄北美枫香侵害特点不同,因此所需防治方法不同;毒死蜱混合氟氯菊酯加代森锰锌搭配树皮穿透剂透翠的化学药剂防治效果显著。In this paper,we invested the characteristics and occurrence regularity of 30-year-old Liquidambar styraciflua infestation by Acanthotomicus suncei,and conducted a preliminary study on its prevention and control,in order to provide a reference for the follow-up control and research of the beetle.In this study,we investigated the damage of bark beetles on L.styraciflua,the main landscape tree species on both sides of Yushan North Road in Changshu city.The damage characteristics of A.suncei on the 30-year-old L.styraciflua were gained.The classification method of the damage level on L.styraciflua was established,and the damage index of A.suncei was calculated.Some preliminary physical and chemical control suggestions were put forward and the control effect was preliminary evaluated.The results showed that the damage of A.suncei was serious,and the damage index reached 46.6.The damage pattern of A.suncei to 30-year-old L.styraciflua was quite different from that of 10-year-old L.styraciflua which in nurseries.The beetle was more likely to attack L.styraciflua than Liquidambar formosana.The rate of tree damage was reduced by more than 80%after control.The infestation characteristics of A.suncei on different tree ages are different,so the required control methods are different.The chemical control effect of chlorpyrifos combined with flumethrin and mancozeb plus bark penetrating agent Patrick is remarkable.
