摘要
在调查的基础上,将获得的有关杨剑舟蛾成虫、卵、幼虫、蛹4个虫态的大量研究数据,通过统计分析得出杨剑舟蛾各虫态及其总体空间分布型为聚集分布,为进一步研究杨剑舟蛾的生物学特性、预测预报及其防治等提供理论根据。
On the base of investigation, by analyzing large quantity of the data about Pheosiafusiformis on the adults, eggs, larvae, pupae, the results showed that the spatial distribution of Pheosiafusiformis was aggregating distribution, and provided the theory of studying the biological properties, prediction and control of Pheosiafusiformis.
