Color morphs induced under controlled environmental conditions in adult Earias insulana (Lepidoptera: Noctuidae)
Environmental Entomology 17 (2), 162-165
Abstract: Different color morphs of adult Earias insulana (Boisduval) could be induced under controlled environmental conditions in the laboratory. Maintenance of laboratory-reared larvae from hatching to pupation, under conditions of 17°C during 14-16 h of dark, and of 21-33°C during 8-10 h of light daily, produced high percentages of grayish brown adults. This process of induction continued through most of the larval stage. Elevating night temperatures above 21°C or day temperatures above 33°C reversed forms of the grayish brown to, the typical form of greenish blue moths. Decreasing the light phase to 8 h or less inhibited the induction of the grayish brown color morphs.
