This report deals with studies of the biology of 10 species of the genus Triatoma Laporte, all of which were collected in Argentina and reared in the Microbiology and Parasitology Institute of the School of Medicine, University of Buenos Aires.The specific purpose of the study was to determine, for each species, average values for number of eggs per female, proportion of eggs hatching, time required for hatching and for the development of each instar nymph, the longevity of female and male adults, and the length of egg-adult and egg–egg cycles.These studies extend the knowledge of the biology of vector species of Chagas’ disease and have been done in conjunction with studies of the geographical distribution of the insects.
