Summary

Morphological analysis of Rhodnius prolixus bugs in Venezuela suggests that R. robustus may not be a distinct species. Genetic drift, not environmental factors, likely explains observed variations in R. prolixus populations.

Area of Science:

  • Entomology
  • Population Genetics
  • Biodiversity Studies

Background:

  • Rhodnius prolixus is a significant vector of Chagas disease.
  • Understanding morphometric variability is crucial for vector control strategies.
  • Previous classifications distinguished R. prolixus from R. robustus based on morphology.

Purpose of the Study:

  • To investigate the morphometric variability within and between Venezuelan populations of Rhodnius prolixus.
  • To assess the species-specific status of Rhodnius robustus in relation to R. prolixus.
  • To explore the drivers of morphological variation in these triatomine bug populations.

Main Methods:

  • Uni- and multifactorial analyses of extensive morphological traits.
  • Comparison of domestic R. prolixus populations with a sylvatic R. robustus population.

  • Analysis of genetic relationships using morphological data and consideration of population genetic models.

    • Main Results:

    • Morphological variability in R. prolixus was not explained by geographic or climatic factors.
    • No correlation was found between morphological and geographical distances.
    • The morphological variation within R. prolixus encompasses the studied R. robustus population, questioning its species status.
    • R. pictipes, R. nasutus, and R. neglectus showed distinct morphological differentiation from each other and from R. prolixus.

    Conclusions:

    • The species-specific status of R. robustus is questioned, suggesting it may be a morphotype of R. prolixus.
    • Observed population structure is more consistent with random genetic drift and founder effects than other models.
    • Morphological differentiation exists among other Rhodnius species (R. pictipes, R. nasutus, R. neglectus).
