摘要
蚱蝉成虫在其产卵危害林内不同时期及日不同时刻的分布均为聚集分布。其聚集度在一日之内随温度的升高而降低，在不同时期随密度和龄期的增大而增强。
The disposition of Cryptotympana atrata adults in the egg-laying forests on the different period and every seconds in a day all belongs to the aggregated distribution.Their aggregation indices are decreased with temperature increasing and are increased with the adult'density intensifying and their age-class raising.
