| [contribution to knowledge of reservoirs of trypanosoma cruzi (chagas, 1909) in corrientes province, argentina]. | in order to identify trypanosoma cruzi reservoirs in transmission areas, 60 mammals in capital and san luis del palmar departments, corrientes, argentina were studied. primates, rodents, carnivores, marsupials and edentates were investigated, 40 of them living in captivity and 20 caught with traps in a rural area. the mammals were examined by xenodiagnosis and third or fourth instars nymphs of triatoma infestans starved for 2 weeks were used. the feces were microscopically observed (400x) for tr ... | 1999 | 10380566 |
| role of enhanced detoxication in a deltamethrin-resistant population of triatoma infestans (hemiptera, reduviidae) from argentina. | deltamethrin and other pyrethroids have been extensively used in argentina since 1980, for the chemical control of triatoma infestans klug (hemiptera: reduviidae). recently, resistance to deltamethrin was detected in field populations by the survival of bugs exposed by topical application to the diagnostic dose estimated on the cipein susceptible strain. results of the current study showed low resistant ratios (rrs) to deltamethrin for the resistant populations (rr ranged from 2.0 for san luis c ... | 2004 | 15273811 |
