To estimate the prevalence of infection with Trypanosoma cruzi in Triatominae species frequently found in and around Mexican dwellings, and to assess the frequency of Triatominae in towns by state.
Between January 1993 and December 1999, 5,399 Triatominae bugs from 14 states of Mexico, were received in the Department of Entomology of the Institute for Epidemiologic Diagnosis and Referral (InDRE), for taxonomic determination and parasitoscopical search of Trypanosoma cruzi. Results obtained between 1993 and 1999 were analyzed globally.
From 13 bug species associated with human dwellings, nine were naturally infected with T. cruzi. The highest percentage of infection occurred in Triatoma pallidipennis, T. picturata, Rhodnius prolixus and T. longipennis. Nayarit, Morelos, and Michoacán were the states with the highest percentage of infected bugs. The species T. dimidiata, T. gerstaeckeri, T. longipennis, T. mexicana and T. pallidipennis were first state records and Pastrongylus rufotuberculatus was a first local record.
These findings stress the importance of studying the biology of Triatominae and the need for permanent surveillance, to allow for up-to-date distribution records of Triatominae species in and around human dwellings, those adapting to human dwellings, and frequencies of those naturally infected by T. cruzi.
评估墨西哥住宅内外常见的锥猎蝽属物种中克氏锥虫的感染率，并按州评估城镇中锥猎蝽属的出现频率。
1993年1月至1999年12月期间，来自墨西哥14个州的5399只锥猎蝽被送至流行病学诊断与转诊研究所（InDRE）的昆虫学部门，进行分类鉴定以及克氏锥虫的寄生虫学检查。对1993年至1999年期间获得的结果进行了综合分析。
在与人类住所相关的13种猎蝽中，有9种自然感染了克氏锥虫。感染率最高的是淡色锥猎蝽、图画锥猎蝽、长红锥蝽和长翅锥猎蝽。纳亚里特州、莫雷洛斯州和米却肯州的猎蝽感染率最高。二色锥猎蝽、格氏锥猎蝽、长翅锥猎蝽、墨西哥锥猎蝽和淡色锥猎蝽是各州首次记录的物种，红瘤前棒线虫是当地首次记录的物种。
这些发现强调了研究锥猎蝽生物学的重要性以及进行长期监测的必要性，以便及时更新人类住所内外锥猎蝽属物种的分布记录、适应人类住所的物种以及自然感染克氏锥虫的物种的出现频率。
