Resistência do Triatoma brasiliensis ao jejum

Abstract

R. resistiram, foi: 33,30 + 1,12; 44,23 + 1,31; 40,28 + 1,78; 48,00 + 1,56; 58,46 + 3,06; 42,63

Resistance to starvation of Rhodnius neivai Lent, 1953 (Hemiptera: Reduviidae: Triatominae) under experimental conditions

“…The great weight reduction registered, with both hosts, in the first week after molting is consistent with the observations of Costa and Perondini (1973) in Triatoma brasiliensis and Cortéz and Gonçalves (1998) in T. rubrofasciata.…”

Influence of blood meal and mating in reproduction patterns of Triatoma brasiliensis females (Hemiptera: Reduviidae) under laboratory conditions

“…Conversely, the life-spans we observed for unfed animals are similar to those reported for unfed Triatoma lecticularia (Jurberg & Costa 1989) and unfed T. brasiliensis (Costa & Perondini 1973). Perhaps, the food source used for our colony may be adequate for maximal fecundity, but may lack some essential substances required for improving longevity.…”

Triatoma rubrovaria (Blanchard, 1843) (Hemiptera-Reduviidae-Triatominae) III: patterns of feeding, defecation and resistance to starvation

“…Afterwards, Perlowagora-Szumlewicz (1954, 1969 noted that insecticide applications must be carried out in preestablished regular periods of time for species that present a high resistance to fast, stating that only then the domiciliary reinfestations can be minimized. Several other authors have conducted extensive studies about various species of triatomines analyzing these biologic aspects, such as Zeledon et al (1970), Costa and Perondini (1973), Jurberg and Costa (1989), and Costa and Jurberg (1989).…”
