“…However, the high mortality rate in the third stage in TA occurred during a period when the highest temperature and relative humidity were recorded. At 33°C and 70% a complete mortality for Rhodnius neglectus fifth nymphal instars was also reported 18 .…”

“…Higher temperature and lower relative humidity also decrease the development time of eggs and nymphs of T. rubrofasciata, T. melanosoma, R. neglectus and R. robustus 6 11 18 19 . Extremely low humidity can interrupt the insect development 15 , although no influence of humidity on egg development time of R. neglectus was found 18 .…”

“…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...

“…Relative humidity – RH is the second physical environmental factor that plays an important role in the biology of these insects, although it is less important than temperature [ 28 ]. The reported effects of RH on bug colonies were highly variable between studies and ranged from no impact to significant effects.…”

A review of data on laboratory colonies of bed bugs (Cimicidae), an insect of emerging medical relevance

Cimicidae are hematophagous Heteroptera, feeding on human blood, that have been the subject of significant medical investigation. In particular, they have been colonized under laboratory conditions to study their medical relevance. Laboratory colonization of these bugs is a multifactorial phenomenon. Our goal was to conduct a comparative literature review to classify the published data, demonstrating preferred bed bug colony conditions. We show that physical factors including temperature, relative humidity and photoperiod, and physiological factors such as type and frequency of blood meals play important roles in laboratory colonies. Any change in these factors produces changes in life-cycle duration. Temperature and blood meal are the most important factors, with a marked impact on the life-cycle of laboratory populations, depending on the species. A wide range of temperatures (15–34 °C) and relative humidity (46–75%) with an average of 25 °C and 59% were found for these colonies. Two widely used blood sources for the colonies were rabbits and humans.
