| abundance and nightly activity behavior of a sylvan population of triatoma dimidiata (hemiptera: reduviidae: triatominae) from the yucatan, méxico. | triatoma dimidiata is the vector of trypanosoma cruzi in the yucatan peninsula (yp). earlier studies have shown that domestic and peri-domestic populations of the vector originated from the sylvan stock and that effectiveness of insecticide-spraying was affected by re-infestations of houses from the sylvan t. dimidiata population. in addition, in the yp most previously published reports have focused on domestic and peri-domestic populations and very little is known about the nocturnal behavior o ... | 2009 | 20836833 |
| variations in sex ratio, feeding, and fecundity of triatoma dimidiata (hemiptera: reduviidae) among habitats in the yucatan peninsula, mexico. | chagas' disease is a major public health concern in most latin american countries and its prevention is based on insect vector control. previous work showed that in the yucatan peninsula of mexico, houses are transiently infested by adult triatoma dimidiata, which then fail to establish sustained colonies. the present study was designed to evaluate the seasonality and possible causes of the dispersal of sylvatic t. dimidiata toward the houses and the subsequent failure of colonization. dispersal ... | 2009 | 19480605 |
| cuticular hydrocarbon variability among triatoma dimidiata (hemiptera: reduviidae) populations from mexico and guatemala. | 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 t ... | 2005 | 16363161 |
| morphometric analysis of triatoma dimidiata populations (reduviidae:triatominae) from mexico and northern guatemala. | triatoma dimidiata is one of the major vectors of chagas disease in latin america. its range includes mexico, all countries of central america, colombia, and ecuador. in light of recent genetic analysis suggesting that the possible origin of this species is the yucatan peninsula, we have analyzed populations from the state of yucatan, san luis potosi, and veracruz in mexico, and a population from the southern region of the yucatan peninsula located in northern guatemala, the region of el peten. ... | 2005 | 16184224 |
