Název v původním jazyce

Effects of crowding, isolation, and transfer from isolation to crowding on total ecdysteroid content of eggs in Schistocerca gregaria

Popis výsledku v původním jazyce

Depending on the developmental time, ecdysteroid content in eggs from crowd-reared females is 5 - 10 times higher than in eggs from the solitary-reared females. Ecdysteroids rise to a small peak at day 3 and a major peak at day 10 of egg incubation. Positive correlation between egg mass and ecdysteroid content was detected at days 10, 12 and 14 in eggs from crowd-reared females. There is no difference between eggs from the bottom and the top of individual egg pods, but variation in ecdysteroid content between egg pods from different females is considerable in all treatment groups. A brief crowding of solitary-reared females at the time of egg laying, a treatment that initiates maternally mediated gregarization of the developing offspring, has no effecton the consistently low ecdysteroid content in the eggs. This result rules out the possibility that the crowding experience of females is transmitted to the offspring by variation in the total amount of ecdysteroids in their eggs
