“…Taking in account that consideration, M. mazzottii as well as M. bassolsae could be considered as effective transmitters of T. cruzi as T. infestans, Rhodnius prolixus, T. rubida sonoriana, nymphs of T. rubrovaria (Pippin 1970, Zeledón et al 1977, Almeida et al 2005, Martínez-Ibarra et al 2005 and some related species of the M. phyllosomus complex, as M. longipennis, M. picturatus, M. mazzottii in a previous study, and M. pallidipennis (Martínez-Ibarra et al 2003a, b, 2005, Martínez-Ibarra & Novelo-López 2004.…”

In consequence, taking into account the associations of those three last species in natural and artificial environments and previous information on its host preferences, the objective of this study was to determine the influence of the blood meal source on the life-cycle, reproductive development and feeding and defecation behavior of M. phyllosomus, M. mazzottii, and M. bassolsae under laboratory conditions. MATERIALS AND METHODSLaboratory colonies of M. phyllosomus and M. mazzottii established in 2004 from specimens captured in Oaxaca, Mexico were used, whereas a colony of M. bassolsae, established in 2004, with specimens originally obtained from Acatlan, Puebla, Mexico, was also used. Colonies were maintained at 27 ± 1ºC and 75 ± 5% relative humidity (rh) and fed weekly on immobilized Leghorn hens or New Zealand rabbits.

“…The large intraspecific variability detected may underlie the known plasticity of T. rubrovaria, making it a potential intradomiciliary invader and consequently an appropriate vector for Chagas disease transmission. Therefore, this triatomine species must be continuously monitored throughout (Bar et al, 2003;Almeida et al, 2005 …”

“…This species is considered a generalistic insect that feeds on a variety of vertebrate and invertebrate hosts (Salvatella et al, 1995). Biological aspects such as feeding, defaecation behaviour, resistance to starvation and life cycle make T. rubrovaria a potential vector for Trypanosoma cruzi transmission (Bar Almeida et al, 2005). In fact, such species has already been found naturally infected with Trypanosoma cruzi in the three countries (Salvatella et al, 1995).…”

Summary :Randomly amplified polymorphic DNA (RAPD) and nuclear ribosomal DNA sequence analyses were used to assess the genetic population structure of the South American triatomine species Triatoma rubrovaria throughout its geographical distribution. To investigate the genetic variability at both intraspecific and intrapopulational levels the RAPD profiles and the nucleotide sequences of the rDNA intergenic spacers, ITS-1 and ITS-2, were analysed and compared. The phenetic analysis based on RAPD profiles show three distinct clusters diverging by similarity coefficients ranging from 0.62 to 0.96. The ITS-1 and ITS-2 sequence variability detected may be considered very high, suggesting reproductive isolation between populations. A total of seven composite haplotypes (CH) were found, among which three are specific for Brazil, other three for Uruguay, and the last one common for the three countries studied. The population studied in Argentina does not represent an independent CH. Sequence analyses proved that the five populations studied are easily differentiable and that there is heterogeneity within each one. True mutations and indels are the responsible of sequence differences between haplotypes and populations, suggesting that divergence processes may presently go on within this species. The large intraspecific variability detected may underlie the known plasticity of T. rubrovaria, making it a potential intradomiciliary invader and consequently an appropriate vector for Chagas disease transmission. Therefore, this triatomine species must be continuously monitored throughout. Résumé

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...
