Introduction: Triatomines are targeted for the control of Chagas disease in endemic areas of Brazil., Methods: Data regarding triatomines captured during 2001-2008 in 34 municipalities in the Northeast of Minas Gerais were analyzed., Results: In total, 11,187 triatomines from eight species were captured, mostly in henhouses and bedrooms. Trypanosomes were found in 203 samples. Main species were Triatoma sordida, Panstrongylus megistus, and Triatoma vitticeps. The number of P. megistus adults was positively correlated with temperature and precipitation, whereas the number of nymphs followed the inverse pattern., Conclusions: Occurrence of triatomines in domiciles indicates the need for sustained entomological surveillance.

Introduction: This work aimed to analyze the triatomine infestation scenario in Jaboticatubas after 30 years of the uninterrupted actions of the Program of Chagas Disease Control., Methods: From 2007 to 2010, household unit infestation was researched, and an exploratory analysis of the localities infested with Panstrongylus megistus was performed., Results: In total, 613 triatomines were captured in 78 households, the majority of which were Panstrongylus megistus and were captured mainly in chicken houses, but they were also found to be colonizing human houses., Conclusions: The epidemiological importance of Panstrongylus megistus was confirmed in Jaboticatubas, and capability to colonize indoors has been demonstrated, as has its proximity to humans. Its distribution is aggregated in the northern and in central-eastern regions of the municipality.

Introduction: Triatomine bug captures in the wild are laborious and time-consuming. Some traps may assist in this task. We report a new trap design and the capture of a specimen of a triatomine rarely found., Methods: Two luminous traps were installed in the city of Diamantina, State of Minas Gerais, and surveyed weekly for a year., Results: A Triatoma arthurneivai female and other triatomine bugs were caught., Conclusions: A new trap design may be used in triatomine bugs field captures, mainly in low density areas. We assume the center of endemism of Triatoma arthurneivai is the Espinhaço Mountain range.
