Behavioural and electrophysiological responses of Triatoma dimidiata nymphs to conspecific faecal volatiles
The behavioural and electrophysiological (electroantennography) responses of the first two instars of Triatoma dimidiata (Hemiptera: Reduviidae) Latreille to fresh and dry faecal headspace volatile extracts from fifth instar conspecific nymphs and synthetic compounds were analysed in this study. Recently emerged nymphs (3–5?days) aggregated around filter paper impregnated with dry faeces and around filter paper impregnated with extracts from both fresh and dry faeces.

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.
Impact of climate change on vector transmission of Trypanosoma cruzi (Chagas, 1909) in North America
Climate change can influence the geographical range of the ecological niche of pathogens by altering biotic interactions with vectors and reservoirs. The distributions of 20 epidemiologically important triatomine species in North America were modelled, comparing the genetic algorithm for rule-set prediction (GARP) and maximum entropy (MaxEnt), with or without topographical variables.
