Table S1. Response of Triatoma dimidiata nymphs to compounds from conspecific dry faeces tested individually and to solvent‐impregnated filter papers as a control. All G tests were not significant. 1A, first instar nymph (3–5 days old); 1B, first instar nymph (10–15 days old); 2A, second instar nymph (7–10 days after ecdysis). Figure S1. Antennal response [electroantennography (EAG)] traces of 1B nymphs (10–15 days old) (A) and 2A nymphs (7–10 days after ecdysis) (B) of Triatoma dimidiata.
