چکیده انگلیسی
The butterfly wing color patterns are unique to a species but are modified in response to cold-shock and tungstate treatments at the pupal stage, producing characteristic temperature-shock (TS) phenotypes that are distinct from the color patterns of seasonal polyphenism. In this study, we examined the efficiency of cold-shock and tungstate treatments for color pattern modifications at the pupal stage in relation to larval rearing conditions for the fall or summer morph using the blue pansy butterfly Junonia orithya. We found that larvae reared under the low-temperature condition that induces the fall morph exhibited hardiness against the color pattern changes imposed by cold-shock or tungstate treatment at the pupal stage. When larvae were fed an artificial diet containing tungstate under the high-temperature condition that induces the summer morph, they were still vulnerable to color pattern changes imposed by cold-shock or tungstate treatment at the pupal stage. Furthermore, larvae reared under the high-temperature condition were subjected to cold-shock or tungstate treatments at the pupal stage. In addition to the expected TS-type changes, these individuals exhibited a reduced number of eyespots in adults, which is a feature of the fall morph. These results suggest that the temperature condition experienced by the larvae, but not their consumption of tungstate, determines the sensitivity of the wing imaginal discs to cold-shock and tungstate treatments at the pupal stage.
