Effects of parental and progeny rearing densities on locomotor activity of 1st-stadium nymphs in the migratory locust, Locusta migratoria: An analysis by long-term monitoring using an actograph

▶ Parental density affected locomotor activity shortly after hatching in the nymphs. ▶ Food-deprivation from nymphs affected the effects of parental and post-hatching rearing density on their locomotor activity. ▶ No evidence was found for behavioral phase accumulation.
