1. 1. Adult, male lobsters held at ambient sea temperature (2–6°C) did not respond to doses of up to 3.0 μg ecdysterone/g live weight, while animals from the same group held at 15°C were all forced into accelerated premolt by 2.0 μg ecdysterone/g. 2. 2. These results were confirmed by a second experiment in which lobsters held at ambient, or 7–10°C, did not respond to doses up to 2.0 μg ecdysterone/g within 62 days while those at 15°C did. 3. 3. Environmental temperature could control molting in the lobster by markedly altering the sensitivity to the molt hormone. |
