摘要
台湾柄天牛是黄山风景区近年来危害壳斗科植物最为严重的蛀干害虫之一。该天牛在黄山风景区2a发生1代,以幼虫在寄主枝干木质部内越冬,成虫5月下旬开始羽化,6月中、下旬为羽化盛期,7月上旬开始产卵,7月中旬孵化为幼虫。台湾柄天牛在黄山风景区的寄主分布广、自然条件适宜、种群密度大、生活隐蔽,致使其在黄山风景区分布范围迅速扩大,给景区的森林植被造成了较大的破坏。建议采用清理枯死木和生物防治等多种方法加以防治。
Aphrodisium sauteri is an important borer attacking oak trees in Huangshan Scenic Spot. It has one generation two years and overwinters as the larva in the trunk xylems of the hosts in Huangshan Scenic Spot. The adult begins to emerge in late May with a peak in mid and late June and oviposit in early July. The egg hatches in mid July. The reasons for the fast spread of the insect in Huangshan are extensive distribution of its hosts, suitable natural conditions, high population density and hidden life. Measures such as cleaning up dead and dying trees and biocontrol were proposed against the pest.
