摘要
以云南省曲靖地区受蠹害的云南松林为调查对象,对林内濒死树上的纵坑切梢小蠹虫和横坑切梢小蠹虫在树干的分布规律进行了研究,提出这两种小蠹虫整体平均分布的格局及不同种的聚集分布的特点。明确了树干各段两种小蠹虫的数量比例,为测报和信息素研究工作提供了基础。
Taking the Pinus yunnanensis trees of Qujing prefecture attacked by Tomicus as target, the law of Tomicus piniperda and T. minor distributed at stem was studied. The pattern of overall distribution of these two pests, and crowding distribution of each species were proposed. The percentage of each pest at different parts of stem was studied and analyzed, which provided the study of forecast and aggregation pheromone with a basis.
