| metric differences between silvatic and domestic triatoma infestans (heteroptera: reduviidae) in bolivia. | one hundred and fifty-seven specimens of bolivian triatoma infestans (klug 1834), including 44 from the silvatic focus at cochabamba (bolivia), were compared using morphometric characters of the head capsule. from these specimens, 10 silvatic and 28 domestic adults were also compared using additional morphometric characters of the membranous part of the hemelytra. nonparametric univariate comparisons between specimens from silvatic and domestic ecotopes indicated the importance of the postocular ... | 1997 | 9379460 |
| smallness of the panmictic unit of triatoma infestans (hemiptera: reduviidae). | the population genetic structure of triatoma infestans (klug), the principal vector of the causative agent of chagas disease in bolivia, was investigated by enzyme electrophoresis at 15 loci, of which 3 were polymorphic. a total of 1,286 adults and nymphs was collected from 19 localities of the cochabamba (high endemicity) and la paz (low endemicity) departments. previous results were confirmed, including a low level of polymorphism (0.20), low genetic distance between geographic areas, and a po ... | 1998 | 9835679 |
| head morphometry and isoenzymatic profile of two triatoma infestans klůg, 1834 (hemiptera, reduviidae) populations. | the triatomine bug triatoma infestans was probably originated in bolivia and dispersed passively over large areas of south america, where it is the major vector of trypanosoma cruzi. in its probable origin area this species shows two different patterns of behaviour, being found both in sylvatic and human related habitats. such behaviour is not observed in other areas of its distribution, where it is exclusive to human related habitats. the main objective of the present study was to evaluate head ... | 2011 | 19653989 |
