RNAi-mediated silencing of dopamine metabolic genes alters pigmentation and induces solitary behavioral change in gregarious nymphs. (A and B) Representative (A) and statistical (B) body color changes induced by RNAi-mediated silencing are shown. Third-stadium nymphs were injected with dsRNA three times at one stadium interval. (C) Behavioral changes induced by RNAi (Mann–Whitney U test, P < 0.01, relative to dsGFP-injected controls). Arrows indicate median P-sol values of the population. DRD1, dopamine receptor D1.
