Abstract : Five species of Triatominae are present in Baja California, Mexico; they are (1) Triatoma rubida, (2) Triatoma protracta, (3) Triatoma peninsularis, (4) Paratriatoma hirsuta, and (5) Dipetalogaster maximus. The principle host of species 1, 3 and 4 above is the wood rat, Neotoma lepida; the hosts for species number 2 above is Neotoma fuscipes and Neotoma lepida; species number 5 above is a very general feeder living in exfoliative rocks with lizards. Triatoma rubida and Triatoma peninsularis were found infected with Trypanosoma cruzi in nature in Baja California; Paratriatoma hirsuta has never been reported infected with Trypanosoma cruzi in nature and no infected P. hirsuta bugs were found infected during this study. Dipetalogaster maximus has previously been shown to possess a low infection rate in nature; no infected D. maximus bugs wer collected in nature; however, these bugs were readily infected with 5 field collected strains of Trypanosoma cruzi. Dipetalogaster maximum has been colonized for the first time. Triatoma rubida was found to use the fish-eating bat. Pizonyx vivesi for its host on Pond Is., Gulf of Lower California. (Author)
