چکیده
|
The operational impact of deltamethrin resistance on the efficacy of indoor insecticide applications to control aedes aegypti was evaluated in merida,mexico. a randomized controlled trial quantified the efficacy of indoor residual spraying (irs) against adult ae. aegypti in houses treated with either deltamethrin (to which local ae. aegypti expressed a high degree of resistance) or bendiocarb (to which local ae. aegypti were fully susceptible) as compared to untreated control houses. all adult ae. aegypti infestation indices during 3 months post-spraying were significantly lower in houses treated with bendiocarb compared to untreated houses (odds ratio <0.75; incidence rate ratio < 0.65) whereas no statistically significant difference was detected between the untreated and the deltamethrin-treated houses. on average,bendiocarb spraying reduced ae. aegypti abundance by 60% during a 3-month period. results demonstrate that vector control efficacy can be significantly compromised when the insecticide resistance status of ae. aegypti populations is not taken into consideration. © 2017 public library of science. all rights reserved.
