[Super-cooling ability and its relations to body's water and fat contents of overwintering Hyphantrian cunea (Lepidoptera: Arcidae) pupae].

The determinations of super-cooling ability and body' s water and fat contents of overwintering Hyphantria cunea pupae showed that during overwintering, the female and male H. cunea pupae had the similar change patterns in their cold-resistance ability, i.e.
