摘要
竹尖胸沫蝉若虫空间分布型属于负二项分布 ;聚集度各指标测定结果表明 :若虫是聚集分布 ;经测定M* =1.2 751+ 1.4 6 86 x,属于聚集分布。并用刀切法对 M*
The distribution pattern of the larvae of Aphrophora notabilis (Walker), obtained by Chi-square test of frequency distribution, obeys negative binomial distribution; The spatial distribution pattern, which was obtained by the index of aggregation, obeys aggregative distribution; The regression equation between M * and is M *=1.2751+1.4686 and the distribution of the larvae is aggregative distribution; The distribution of larvae, obtained by assessing and checking M *with Jackknifing and F-test method of deviation, obeys aggregative distribution.
