| 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 |
