| 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 |
| relative contribution of monooxygenase and esterase to pyrethroid resistance in triatoma infestans (hemiptera: reduviidae) from argentina and bolivia. | recently, high resistance to pyrethroid insecticides has been associated with ineffective field treatments against triatoma infestans (klug) (hemiptera: reduviidae) in northern argentina. samples were collected from two areas in argentina (salta and la rioja) and one are in bolivia (yacuiba), and they were subjected to toxicological and biochemical assays. all populations were resistant to deltamethrin, but they showed different profiles to nonpyrethroid insecticides. the salta population showed ... | 2008 | 18402146 |
