Data analysis In Y-tube olfactometer trials, Chi-square tests (X 2 ) were used to evaluate the difference of responses to fecal extract (test) and ethanol (control). In filter paper contact bioassays, two-sided binomial tests were used to evaluate the preferences of individual mites for guanine. The criterion or statistical significance was set at P < 0.05, and all analyses were carried out in SPSS v24.0. The total percentage of mites (% responding) responded to both guanine and water (control). Two-sided binomial tests were used to evaluate the preferences of individual mites for guanine ( P < 0.05). UM: Unvarnished female mites; VTFM: Varnished the tips of the foreleg tarsi of mites with nail polish; VBM: Varnished the back of mites with nail polish.
