“…Data concerning the life cycle of P. herreri are scarce in the literature, but our results were similar to those observed in a previous study that used comparable temperature conditions 8 . Silva and Silva 8 demonstrated the impact of two distinct temperatures on the development of several triatomine species, including P. herreri, and they concluded that triatomines exposed to temperatures as high as 30°C exhibited a shortened life cycle compared to those exposed to a lower temperature (25°C).…”

Introduction: Panstrongylus herreri is a main Chagas disease vector, and its success as a vector stems from its ability to establish domiciliated colonies; we aimed to explore its biology and reproduction. Methods: The average amount of blood ingested and the time from the beginning of a blood meal to the production of feces were recorded. Results: Females exhibited a higher blood ingestion rate than males, but similar defecation times and frequencies were observed. Conclusions: Despite the detected decrease in oviposition rates, P. herreri's potential as a Chagas disease vector in environments other than the Amazon forest cannot be discounted.

“…These three life history traits observed in various triatomine species (Feliciangeli & Rabinovich 1985, Cabello et al 1987, da Silva & da Silva 1989, Cabello & Galíndez 1998) correspond to those described by Heppell et al (2000) for long-lived species that mature late and have few offspring, where fecundity and early offspring survival are less critical than pre-adult survival to maturity [a "slow" strategy observed along several taxa, such as the "slow" mammals described by Read and Harvey (1989)]. The long development time and longevity, as well as the relatively low fecundity of B. ferroae , could represent an adaptive strategy for environments that are relatively "crowded" or display low food availability where selection favours efficiency of the conversion of food into offspring and minimises waste (Rabinovich 1974).…”

Triatominae are widely recognised for their role as vectors of Trypanosoma cruzi. One of the main biological characteristics of this subfamily is their obligate haematophagous condition. However, previous studies on Belminus herreri and Belminus ferroae suggested that cockroaches are their principal hosts in domiciles. Due to this peculiar behaviour, the aim of this study was to analyse several demographic and reproductive parameters of B. ferroae fed on three different hosts (mice, cockroaches and Rhodnius prolixus) and relate B. ferroae fitness to these alternative hosts. The cohorts were reared under constant conditions. The egg hatching rate was similar for cohorts fed on cockroaches (69.4%) and R. prolixus (63.8%), but was much lower for the cohort fed on mice (16%). The development time from the nymph to adult stage and the average age of first reproduction (α) presented lower values in the cohort fed on cockroaches, which is consistent with the higher population growth rate associated with this host. Demographic parameters [intrinsic rate of natural increase, finite rate of population growth, net reproductive rate and damping ratio] showed statistically significant differences between the cohorts. Analysis of the life history of B. ferroae revealed a higher fitness related to the cockroach. The implications of these results for the origin of the subfamily are discussed.

“…A partir do 40 estádio os frascos usados eram maiores, com 3,8 cm de diâmetro por 7 cm de altura (SILVA, 1985) Às ninfas de 10 estádio a alimentação foi oferecida no 100 dia após a eclosão das mesmas e, para as de 29, 39, 40 e 59 estádios os intervalos foram de 15,20, 25 e 35 dias, respectivamente, após a ecdise. Estes intervalos foram considerados ideais, pois permitiu ao triatomineo atingir o estado de repleção total (SILVA & SILVA, 1989b) , que possibilita a ecdise com apenas uma alimentação por estádio.…”
