| Popis: | The geographic variation in the cuticular hydrocarbon pattern among 11 populations of Triatoma dimidiata Latreille (Hemiptera: Reduviidae: Triatominae) from different regions of Mexico and Guatemala, was studied using capillary gas chromatography. T. dimidiata populations were differentiated based on the relative amounts of 71 hydrocarbon components. Insect population classification was mostly in agreement with their geographical vicinity; Mexican populations from the Yucatan peninsula grouped together with those from northern Guatemala, insects from the Mexican Gulf coast states were closely related to those collected from northern Oaxaca, and to a lesser extent, to insects from Chiapas. Insects from southern Oaxaca were clustered together with those from southern Guatemala. All these populations were clearly separated from Guatemalan specimens collected in caves from Alta Verapaz. |
