Excretion on the food medium in Con-Ex. Data are percentage of excreted dye found on the food medium. (A) The percentage of dye on 2Y10S3C medium (ExMedium %) was indistinguishable in r[A] and LS females (two-tailed t test, p = 0.5738, n = 8). (B) Food medium composition influenced ExMedium % (one-way ANOVA, p < 0.0001, n = 6–10). Compared to 2Y10S3C, ExMedium % was significantly greater on 30Y10S3C (*Bonferroni’s multiple comparison, p = 0.0366) and lower on 2Y30S3C (*Bonferroni’s multiple comparison, p = 0.0009. (C) ExMedium % was lower on 2Y10S10C than on 2Y10S3C (*two-tailed t test, p < 0.0001, n = 8).
