Abstract
From August 1997 to August 1998, 334 specimens of Triatoma longipennis and 62 of T. picturata were collected in four groups of localities placed in th e zone from Guadalajara, Jalisco to TL pic, Nayarit, in the West Coast of M exico. Most T. longipennis were collected outdoors (69.2%) while most T. pi cturata (58.1%) were collected indoors. All collected specimens were examin ed for Trypanosoma cruzi infection, which was detected on 98 (29.3%) T. lon gipennis and 17 (27.4%) T. picturata. This study confirms the role of T. lo ngipennis and T. picturata as some of the main T. cruzi vectors to humans i n Mexico. Habitation Infestation Rate with T. longipennis was of 0.09 and w ith T. picturata was of 0.03 and the predominating ecotopes were pile of bl ocks, chicken coops, pigsties, wall crawls and beds.
