Morphometric differentiation, Triatoma Dimidiata, GuatemalaAbstract
A dwelling from Agua Zarca (Ixhuatán, Santa Rosa) and another from El Cuje (Pueblo Nuevo Viñas, Santa Rosa), were selected to study the populations of Triatoma dimidiata insects they housed. In each dwelling, a group of insects collected during the hot and dry months and another collected during the rainy months were selected. These groups were compared using traditional morphometric techniques to detect possible differences between them and to analyze the nature of these differences. The El Cuje groups did not present morphometric differentiation, but the Agua Zarca groups presented a slight but significant differentiation. The results indicate that the populations of T dimidiata present movements, and that in some areas there may be at least two populations that can be differentiated morphometrically. Climatic factors such as temperature and rainfall have an influence on the start of these population movements, which can even cause populations that are not normally found in human dwellings to invade them.
It is very likely that these population movements of adults occur during the hot and dry months, so this time is recommended to apply control treatments.
