Temperature increase can cause hyperecdysonism in American lobsters (Homarus americanus) injected with ecdysterone

Journal Article:

Abstract

In the lobster Homarus americanus the threshold dose for premolt acceleration by ecdysterone can be altered by changes in temperature. Two dose levels of ecdysterone (0.5 and 1.0 ..mu..g/g body weight) were compared at three different temperatures (10, 17, 21/sup 0/C); all three doses remained subthreshold at 10/sup 0/C but at 17/sup 0/C the 1.0-..mu..g dose caused hyperecdysonism--rapid but abnormal completion of premolt terminating in death at ecdysis. In contrast, the 0.5-..mu..g dose remained subthreshold even at 21/sup 0/C. These results demonstrate a dose-temperature relation for response to injected ecdysterone.
