Abstrakt:	Body color in insects changes according to the living environment and physiological stresses possibly involved in endocrine factors. To date, 3 predominant bioactive peptides, Corazonin, Elevenin, and pigment-dispersing factor (PDF), have been illuminated to be involved in the body color in insects and crustaceans. Here, we examined the possibilities that these 3 factors would contribute to body color changes via melanization in the two-spotted cricket, Gryllus bimaculatus, whose body color changes according to population density drastically. Quantitative analyses revealed the higher transcriptional levels of Corazonin and Elevenin in the crowded-conditioned crickets, whereas the transcriptional level of PDF was higher in the isolated-conditioned crickets. However, the body color was not changed by knockdown of Corazonin, Elevenin, and PDF by RNA interference. The present data indicated that coloration mechanisms in G. bimaculatus is differently controlled from the previous observation in Locusta migratoria, a closely related orthopteran species.
