摘要: 旨在为黄河三角洲地区危害白蜡树云斑天牛的防治提供指导,对危害白蜡树云斑天牛种群不同虫态的数量动态和频次进行研究。通过调查白蜡树林地云斑天牛的产卵刻槽、排粪孔和羽化孔的数量,研究卵、幼虫和成虫(蛹)种群数量动态和频次。危害白蜡树云斑天牛种群卵、幼虫和成虫(蛹)的种群增长曲线是凹形,卵期虫口数大,死亡率也高。单株树上卵、幼虫和成虫(蛹)的数量与其频数负相关,单株白蜡树受云斑天牛危害的加重,同一受害程度树木的株数下降。云斑天牛种群的卵、幼虫、成虫(蛹)的频次统计均为负二项分布,不同虫态所对应的空间分布格局为聚集分布。危害白蜡树和杨树种群云斑天牛种群的空间分布和动态变化基本相同,危害寄主对云斑天牛的空间分布和动态变化影响较小。

Abstract: The aim is to provide guidance for controllingBatocera horsfieldi in ash tree in the Yellow River Delta. In the paper, quantitative dynamics and frequency of egg, larva, adult (pupa) population were studied by investigating the quantities of egg niche, frass hole and emergence hole ofB. horsfieldi in ash tree. The results showed that,B. horsfieldi population increasing survivorship curve was concave type, population of egg was large, and mortality was also high in the egg stage. There was a negative correlation between eggs, larva and adult (pupa) population number per tree and their frequency number. With the increasing damage of B. horsfieldi per tree, the number of damaged trees with the same damage degree declined. The frequencies classify statistics of eggs, larva and adult (pupa) were all negative binomial distribution, the corresponding spatial distribution patterns of different developmental stages were clumped distribution. The spatial distributions and dynamic changes ofB. horsfieldi population in ash tree and poplar populations were almost the same. The host had less influence on the spatial distributions and dynamic changes ofB. horsfieldi .
