行为阶段变化的时间过程中进行了调查，在Schistocerca gregaria，使用逻辑回归分析的行为记录在一个标准的分析。 肝硬化发生得非常迅速。 在被置于人群中的1- 4小时内，单独饲养的鱼的行为变得明显合群。 这些昆虫重新孤立同样迅速，如果从人群中删除。 群聚饲养的蝗虫也在1- 4 h内发生孤化，但这种效应并不完全。 结果表明，虽然行为gregarization是最大的拥挤在几个小时内，孤立是一个两阶段的过程，首先迅速变化，然后更慢的功能，以前的拥挤。
The time-course of behavioural phase change was investigated in nymphs of Schistocerca gregaria, using logistic regression analysis of behaviour recorded in a standard assay. Gregarization occurred very rapidly. Solitary-reared nymphs became markedly gregarious in behaviour within 1-4h of being placed in a crowd. These insects re-solitarized equally quickly if removed from the crowd. Crowd-reared locusts also solitarized within 1-4h, but this effect was not complete. Results indicate that, while behavioural gregarization is maximal within a few hours of crowding, solitarization is a two-stage process, changing rapidly at first, then more slowly as a function of the period of previous crowding.
