Abstrakt: Larvae of the beetleDendroides canadensis accumulate protein antifreezes during the winter.D. canadensis which were collected in the early fall, prior to the initiation of cold hardening processes, were treated with either 3.3 or 6.6 µg juvenile hormone I topically in acetone and maintained for 21 days under normally non-inductive acclimation conditions (16 light/8 dark, 20 °C). Hormone treated animals significantly elevated the levels of antifreeze protein in their hemolymph compared to those of acetone treated and untreated controls or animals measured on the day of collection.
