摘要： 为做好危害杨树云斑白条天牛的防治工作，以洞庭湖地区危害杨树云斑白条天牛为调查对象，通过调查产卵刻槽、排粪孔和羽化孔的数量来确定卵、幼虫和成虫（蛹）的种群数量，然后对不同虫态种群数量的增长规律和频次比较进行了研究。结果表明：云斑白条天牛卵、幼虫和成虫（蛹）的种群数量增长呈正金字塔型，卵期虫口数大，死亡率高，存活曲线符合凹型曲线的增长规律。单株树上卵、幼虫和成虫（蛹）的种群数量与其统计频数负相关，表现为随单株树受害程度的加重，同一受害程度树木的株数下降。不同虫态的频次统计结果均符合负二项分布，表明云斑白条天牛种群的卵、幼虫、成虫（蛹）的空间格局为聚集分布。

Abstract: In order to control Batocera lineolata on polar, increasing law and frequency of B. lineolata egg, larva and adult (including pupa) population were studied by investigating oviposition incision, frass hole and emergence hole on the poplars in the region of Dongting Lake. The results showed that the increasing law of B. lineolata egg, larva, adult (including pupa) population was like an upward pyramid. The B. lineolata egg population was large, and the mortality was high in the egg stage, therefore the population increasing survival curve was concave type. The egg, larva and adult population number per tree had negative correlations with the corresponding tree numbers, indicating that with the increasing population number of Batocera lineolata, the number of damaged trees with the same population frequency decreased. B. lineolata egg, larva, adult (including pupa) all presented an aggregated distribution as the frequency of B. lineolata in different developmental stages were all in accordance with negative binomial distribution.
