Abstract

Biology of Triatoma pseudomaculata Correa & Espinola, 1964, under
Laboratory Conditions (Hemiptera:Reduviidae:Triatominae) - 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)=398+/-76 days.
The following parameters were observed: the time immature stages took to
develop from egg to adult emergence; the occurrence 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 until the next and the defecation pattern. The
experiment was carried out for 20 months, held in BOD incubator with the
average of temperature and humidity of 28+/-1 C and 80+/-5% RU,
respectively.
