RESUMO

Observations were made on the evolutive cycle of Triatoma pseudomaculata, held under laboratory conditions, fed weekly on bird (pigeon). Of 60 eggs obtained, only 34 nymphs reached the adult stage in a period of X(S)=398ñ76 days. The following parameters were observed the time immature stages took to develop from egg to adult emergence; the occurence of the first meal; the time-lapse between the presenting of the blood-meal and the begining of feeding; time of feeding; amount of blood ingested; variation of weight 24 hr after the blood-meal and unit the next blood-meal; and the defecation pattern. The experimental was carried out for 20 months, held in BOD incubator with the average of temperature and humidity of 28ñ1ºC and 80ñ5 per cent RU, respectively.
