“…Several studies have shown the influence of temperature on the development of triatomines (Juárez & Silva, 1982; Silva, 1988; Cabelo, 1999; Luz et al ., 1999). The environmental temperature affects the fecundity and the maturity rate of T. infestans (Jörg, 1960, 1989) and Mepraia spinolai (Ehrenfeld et al ., 1998).…”

Abstract. The effects of temperature on the development of early stages and the thermopreference of nymphs and adults were analysed in the haematophagous bug Triatoma brasiliensis Neiva, 1911 (Hemiptera, Reduviidae). Egg hatching, mortality of nymphs, feeding and moulting success of the early stages of T. brasiliensis were all affected by temperature. While high rates of egg hatching were observed between 25 and 27 C, no hatching occurred at 12, 19 and 38 C.

“…En consecuencia, es difícil comparar los resultados sobre ciclos de vida existentes en la literatura, debido a las variaciones experimentales de cada trabajo. Por ejemplo, para algunas especies de Rhodnius se han reportado promedios de 102 y 120 días, como es el caso de R. ecuadoriensis (15); de 101, 127 y 209,4 días para R. nasutus (16,17); de 104, 131, 154,2 y 177,1 días para R. neglectus (18,19); de 181,2, 118, 86,7 y 68,9 días para R. neivai (20,21); de 212 y 126 días para R. pallescens (22); de 190,7, 278 y 118 días para R. pictipes (20,23,24); de 114, 140 y 118 días para R. prolixus (20,25), y de 114 y 135 días para R. robustus (26). En otros géneros de triatominos se han observado promedios de 196,8 y 189,5 días para Meccus picturatus (27); de 230,3 días para Triatoma flavida (28), y de 180,1 días para T. rubrovaria (29).…”

Introducción. Rhodnius colombiensis es un triatomino silvestre asociado a palmas de vino (Attalea butyracea) en la cuenca alta del río Magdalena (Colombia). La frecuente invasión de estos vectores al domicilio y las elevadas prevalencias de Trypanosoma cruzi en infecciones naturales constituyen un riesgo en la transmisión de la enfermedad de Chagas. Objetivo. Comparar la duración del ciclo de vida de R. colombiensis y R. prolixus en condiciones de laboratorio. Materiales y métodos. Se utilizaron 92 insectos de cada especie. Se estudió la duración de cada estadio, el número de comidas por estadio, el porcentaje de mortalidad, la causa de muerte, el promedio de huevos puestos por cada hembra, el número de huevos fértiles y la longevidad de los adultos. Resultados. Los promedios de duración de todos los estadios de desarrollo de R. colombiensis fueron mayores que en R. prolixus, presentando diferencias significativas en el tiempo transcurrido desde huevo hasta adulto. Los promedios de huevos puestos y huevos fértiles, presentaron diferencias significativas, siendo mayores en R. prolixus que en R. colombiensis. El porcentaje total de mortalidad de R. colombiensis fue de 31,5% y de 6,5% para R. prolixus. La longevidad en las hembras fue mayor en R. prolixus. Conclusiones. Los estadios de R. prolixus tienen menor duración, las ninfas en general realizan menor número de comidas que R. colombiensis, los adultos de R. prolixus toman mayor número de comidas y ovipositan mayor número de huevos fértiles, presentando hembras con mayor longevidad. Todos estos parámetros indican que R. prolixus presenta mejor éxito reproductivo que R. colombiensis, en las condiciones experimentales utilizadas. Los datos inéditos sobre el ciclo de vida de R. colombiensis serán de utilidad para el mantenimiento de las colonias en el laboratorio. Materials and methods. Ninety-two individuals for each species were studied. The mean duration time of each stage, the number of bloodmeals for each stage, the percentage of mortality, the cause of death, the mean of eggs laid by female, the number of fertile eggs and the longevity of adults were recorded. Results. The mean duration time of all stages of R. colombiensis was higher than in R. prolixus, producing significant differences in the overall time from egg to adult. The mean of total eggs and fertile eggs showed significant differences, being higher in R. prolixus than in R. colombiensis. The total mortality was 31.5% for R. colombiensis and 6.5% for R. prolixus. The longevity of females was higher in R. prolixus. Conclusions. The stages of R. prolixus are of relatively short duration. In general, the nymphs take fewer bloodmeals than R. colombiensis, the adults take more bloodmeals and oviposit a larger number of fertile eggs, and females have a greater longevity. These parameters indicated that R. prolixus has superior reproductive success in comparison with R. colombiensis under the experimental conditions used. These new life cycle data of R. colombiensis will be useful for maintenance of labo...

“…Since Rabinovich (1972a) superb paper on Triatoma infestans (Klug), vital statistics under laboratory conditions, the development of biodemographic studies on triatomines has been very prolific and life‐table studies on several species have been carried out ( Rabinovich , 1972b; Rodríguez and Rabinovich , 1980; Zeledón , 1981; Feliciangeli and Rabinovich , 1985; Cabello et al., 1987; Cabello and Galíndez , 1998; Guarneri et al., 1998; Cabello , 1999). The importance of such studies is because they, together with field observations, provide critical information: (i) to design optimal control strategies, (ii) on the population potential growth and its relationship with invasibility, the ability of a species to become established after the introduction of some individuals into a new habitat ( Rabinovich , 1972a; Carey , 1982).…”

Rhodnius prolixus Sta˚l (Reduviidae: Rhodninii) is one of the most important vectors of Chagas disease. As a result of its medical importance, several life history studies have been carried out, but in general with a restricted demographical scope, without assessing the potential tradeoffs in the life history of this insect. In this study, individuals of R. prolixus were kept in two spatially different habitats and several fitness components were measured. The results show that life expectancy in adults is negatively correlated with gross fecundity, indicating a cost of reproduction. Life expectancy is shorter for males and longer for individuals of the same sex in the more complex habitat, where the fitness is lower compared with that of the simpler habitat.
