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 the zone from Guadalajara, Jalisco to Tepic, Nayarit, in the West Coast of Mexico. Most T. longipennis were collected outdoors (69.2%) while most T. picturata (58.1%) were collected indoors. All collected specimens were examined for Trypanosoma cruzi infection, which was detected on 98 (29.3%) T. longipennis and 17 (27.4%) T. picturata. This study confirms the role of T. longipennis and T. picturata as some of the main T. cruzi vectors to humans in Mexico. Habitation Infestation Rate with T. longipennis was of 0.09 and with T. picturata was of 0.03 and the predominating ecotopes were pile of blocks, chicken coops, pigsties, wall crawls and beds.
1997年8月至1998年8月期间，在墨西哥西海岸从哈利斯科州瓜达拉哈拉到纳亚里特州特皮克的四个地区组中，采集了334份长红锥蝽标本和62份图氏锥蝽标本。大多数长红锥蝽是在户外采集的（69.2%），而大多数图氏锥蝽（58.1%）是在室内采集的。对所有采集的标本进行了克氏锥虫感染检测，在98份（29.3%）长红锥蝽和17份（27.4%）图氏锥蝽中检测到感染。本研究证实了长红锥蝽和图氏锥蝽作为墨西哥一些主要的人类克氏锥虫传播媒介的作用。长红锥蝽的居住侵扰率为0.09，图氏锥蝽为0.03，主要的生态位是砖块堆、鸡舍、猪圈、墙壁爬行处和床铺。
