The members of the subfamily Triatominae (Heteroptera, Reduviidae) are vectors of Trypanosoma cruzi (Chagas), the causative agent of Chagas disease or American trypanosomiasis. As important vectors, triatomine bugs have attracted ongoing attention, and thus, various aspects of their systematics, biology, ecology, biogeography, and evolution have been studied for decades. In the present chapter, the authors summarize the current knowledge on the systematics, phylogeny, evolution, and biology of these vectors and discuss the implications for human health.

“…In T. carcavalloi, the obtained rate of 38.3% is considered low compared to those of Triatoma flavida, in which 93% of eggs have been reported to hatch 27 ; T. pseudomaculata, with a rate was 88.3% 28 ; and T. rubrovaria 29 , Triatoma dimidiata 30 , T. infestans 31 , T. maculata 32 33 and Triatoma pallidipennis 34 , in which rates range from 60 to 80%. In the Rhodnius genus, temperature was observed to influence not only the incubation period but also the incidence of hatching, as shown for R. robustus 35 .…”

Introduction:Triatoma carcavalloi is a wild species that is found in sympatry with Triatoma rubrovaria and Triatoma circummaculata, which are vectors of Trypanosoma cruzi currently found in rural areas of Rio Grande do Sul, Brazil. Methods: Fertility was assessed and to determine the incubation period, the eggs were observed until hatching. The first meal was offered to 1 st stage nymphs. The intermolt period was also determined. The number of blood meals was quantified at each nymphal stage and the resistance to fasting as the period between ecdysis and death. Mortality was assessed and longevity was determined by recording the time that elapsed from molting to the adult stage and until death. The developmental cycle was assessed by recording the length in days of each stage from molting to adult hood. Results: The average incubation period was 22.7 days. The average first meal occurred 3.1 days after hatching. The 5 th stage nymph to adult intermolting period was the longest at 193.4 days. The average number of feedings during nymphal development was 13.4. The resistance to fasting assay indicated that the 3 rd , 4 th and 5 th stage nymphs presented higher resistance than did adults. The highest mortality rate was observed in the 3 rd stage nymphs (22.2%). The average length of adult survival was 25.6 weeks, and the average total life cycle lasted 503.4 days. Conclusions:This study is the first report on the biology of T. carcavalloi that fed on mice. The presented findings expand the bionomic knowledge of these species.

“…The number of interactions for blood feeding between the triatomine and the host is proportional to the risk of transmission of T. cruzi (Rocha et al, 2001). The feeding of T.williami on birds resulted in a greater number of blood meals between the ecdysis, which in natural conditions could increase the risk of predation during feeding.…”
