摘要:
自 2012 年至 2019 年采用踏查和专项调查相结合的方法,对广东省樟树 Cinnamomum camphora 枝干有害生物危害进行了调查。调查结果表明,樟树枝干病虫害共 18 种,其中病害 3 种、有害 植物 7 种、虫害 8 种,樟树溃疡病 Physalospora sp. 和肉桂双瓣卷蛾 Polylopha cassiicola 为严重发生种类, 樟树炭疽病 Glomerella cingulate 和樟密缨天牛 Mimothestus annulicornis 为中度发生种类。因此应加强抗病 虫品种选育研究,综合运用多种防治措施相结合,将枝干病虫害控制在允许的经济阈值以下。

Serious damaged species contains 2 species, Physalospora sp. and Polylopha cassiicola, moderately damaged species contains 2 species also, Glomerella cingulae and Mimothestus annulicornis. Space distribution and damage characteristics of main harmful species are accounted, the occurrence trend is predicted, and related controlling methods are advised.
