Abstract : Over 200 small rodents and several hundred fleas have been collected at high elevations in the Chisos Mountains in Texas. Collections made at elevations in excess of 7,000 feet are represented by four genera of fleas. One (Hystricopsylla) represents the first record of this genus in Texas. Preliminary field test of a new trap for flying insects shows promising results for collecting adult mosquitoes. Trap is designed on the principle of the Shannon Dawn Trap, but collects insects automatically and alive. Deinocerites pseudes were collected for the first time in the United States. Biting collections indicate D. pseudes will readily feed on man. Host crabs have been associated with this species. A review of the literature indicates sixteen species of reduviid bugs were reported naturally infected and five experimentally infected with Trypanosoma cruzi in the United States. Fifteen natural reservoirs and twenty-eight experimental reservoirs were recorded. Naturally infected reservoirs of T. cruzi were found over a broader geographic range than naturally infected vectors. (Author)
