纵坑切梢小蠹和横坑切梢小蠹是中国主要的森林蛀干害虫。在云南,两虫经常在云南松等松类树种上共同危害,造成重大生态和经济损失。这两种小蠹的种群结构因地区而异,其性比、成虫在枝梢上聚集危害的时间及其在树冠上的空间分布规律基本相同,但在树干上的空间分布规律有很大差异。通过研究并比较这两种小蠹的种群结构、性比、季节分布及空间分布等生态学特性差异,对防治有重要意义。
Cutworm and Beetle are the major forest borer pests in China. In Yunnan, the two insects often endanger pine and other pine species, causing major ecological and economic losses. The population structure of these two species of beetles varies from region to region and their sex ratio is similar to that of adult adults and their spatial distribution on the canopy is quite similar. However, the spatial distribution of the species on the trunk is quite different . By studying and comparing the ecological characteristics of these two species of beetles, such as population structure, sex ratio, seasonal distribution and spatial distribution, it is of great importance to prevention and treatment.
