The painless mutant shows no avoidance to AITC for oviposition choice. Oviposition sites were measured on a split plate containing equal areas of media and media plus 1 mM AITC. For the control genotype (w¹¹¹⁸), there were significantly more eggs laid on the non-AITC side (P = 0.005 wilcoxon signed rank test), whereas for the pain⁰¹ and double mutant lines there was no significant preference for one side. In the dTRPA1⁰¹ line, there is a significant preference for the solution containing AITC (P = 0.002 wilcoxon signed rank test). N’s refer to the total number of eggs counted.
