Resumo
Due to its capacity to develop in an artificial environment, large-scali:
laboratory breeding ability and widespread use in experimental Chagas
disease testing, the biology of Triatoma costalimai was studied. The bug was
first discovered infected by Tiypanosoma cruzi (costalimai strain) by Melo &
Borges (1981). In this study, the experiment was carried out aí 28° C, 75+5%
humidity and a 12-hour light/dark cycle. The eggs incubation and íts
complete development was carried out in polyethylene flasks measuring 3,0 x
7,0 cm, wkh individual bug specimens. The mean egg incubation period was
21+00 days for males and females, with the evaluative cycle mean duratiou
of 138,5 days for males and 136,1 days for females. Daily observation and
collection of exuvias determinate the duration of the nymph stages. Mean
fecundity and fertiíity were 75.2 + 8.5 eggs and 90.4% respectively, and lhe
mean number of postures was 17.4 + 1.2 with a mean of 4.1+ 0.3 eggs per
posture. The mean resistance to fastening, in crescent order of nymph stagLis
and adults (males) was of 35,8 + 0,6; 44,8±2,2; 90,6±4,1; 117,4±6,l;
138,1±7,2 and 67,5±l,6.The mean feeding period for male nymphs was
12,0±2,4; 6,812,1; 3,1±0,6; 6,3±2,0; 3,9±0,7 and for females 9,3±l,3;
5,111,0; 3,4±0,6; 4,3±0,7; 5,711,7.
