采用动态记录仪观察了不同亲代饲养密度和后代饲养密度对迁徙蝗（Locusta migratoria）第1运动场若虫运动活动的影响。新孵化的若虫在孵化后不久出现一个小的活动高峰，群体饲养的成虫后代（群居若虫）的活动高峰水平显著高于孤立饲养的成虫后代（独居若虫）。然而，两组在初始峰值后表现出的最大活动水平没有显著差异。在2日龄若虫2-5h的测量中，孵化后拥挤增强了运动活动。在这种情况下，亲代密度对运动活动没有显著影响。然而，在观察期后期，群居若虫的最大活动水平高于独居若虫。有趣的是，这种亲代效应在群体饲养的若虫中比在单独饲养的若虫中更为明显。亲本密度似乎会影响后代对拥挤的反应程度。在运动活动方面没有发现相积累的证据。在地理种群中观察到的运动活动差异并不符合它们的系统发育关系。
The effects of parental and progeny rearing densities on locomotor activity in 1st-stadium nymphs of the migratory locust, Locusta migratoria, were observed over a 24- or 36-h period using an actograph. Newly hatched nymphs showed a small activity peak shortly after hatching and the peak level was significantly higher in offspring (gregarious nymphs) of crowd-reared adults than in those (solitarious nymphs) of isolated-reared adults. However, no significant difference was found between the two groups in maximum activity levels exhibited after the initial peak. Post-hatching crowding enhanced locomotor activity during 2–5h of measurements in 2-day-old nymphs. In this case, the parental density resulted in no significant influence on locomotor activity. However, the maximum activity level shown later in the observation period was higher in gregarious nymphs than in solitarious nymphs. Interestingly, this parental effect was more pronounced in nymphs reared in group than in those reared in isolation. The parental density appeared to affect the degree of response to crowding in the progeny. No evidence was found for the phase accumulation in terms of locomotor activity. The variation observed in locomotor activity among geographical populations did not correspond to their phylogenetic relationships.
