摘要:
Larvae ofColias eurythemeBoisduval were reared under controlled environments to dctermine if seasonal color variation among adults is a response to the physical environment. A temperature effect was discovered, but it was not expressed until the adult stage of the generation subsequent to the treated generation. Temperatures of 26.6°C or 32.2°C produced the orange summer form, whereas 18.3°C produced the yellow winter form.
