Observations on Vectors of Chagas' Disease in the United States

Abstract

Summary A resumé of the 1941 collecting data for the Alvarado Mine is given, making a total of 699 cone-nosed bugs examined from Arizona. Twenty-eight or 4 per cent of these bugs were infected with Trypanosoma cruzi. The tolerance of rodents to feeding of cone-nosed bugs is recorded. Xenodiagnosis of native mammals has so far yielded negative results.
