摘要: The hyperactivity, incoordination, recovery, and mortality produced by four α-cyanopyrethroids usually used for Chagas disease vector control (β-cypermethrin, β-cyfluthrin, λ-cyhalothrin, deltamethrin) were evaluated on third instar nymphs of Rhodnius prolixus. All pyrethroids modified the locomotor activity nymphs, which increased linearly as a function log insecticide concentration. λ-Cyhalothrin showed lowest values Effective Concentration 50%, Lethal Time 50% when insecticides applied contact with treated filter papers. Recovery from incoordination was observed after topical application insecticides. recovery inhibited simultaneous piperonyl butoxide, suggesting that biotransformation mixed-function microsomal oxidases is involved in process recovery.
