| 摘 要： | 本文调查和计算结果表明二氧波缘龟甲幼虫在寄主植物泡桐上的空间格局为聚集型的二项式分布，建立的ＬｇＶ－ｌＧｍ和Ｍ－Ｍ的回归直线方程也说明该幼虫的空间格局为聚集分布；笔者比较了该幼虫在树内的格局，用ｌｗａｏ的方法确定理论抽样数。

| Abstract: | This papper reported the results of studies on the spatial pattern and sampling technology of the larva of Basiprionata bisignata Boheman. The distribution pattern of the larva is negative binomial distribution by the method of frequency distribution comparison. The determined results of partial indices of aggregation intensity showed that the spatial pattern of the larva is aggregation pattern. The lgV=lgM and M-M regression lines were established. The difference of the pattern of the larva on east, west, south, north position crown and on upper, middle, lower layer crown were also compared. The theoretical sampling size was defined by Iwao's method. |
