Deltamethrin resistance in Aedes aegypti results in treatment failure in Merida, Mexico
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 ... -
Efficacy of novel indoor residual spraying methods targeting pyrethroid-resistant Aedes aegypti within experimental houses
Challenges in maintaining high effectiveness of classic vector control in urban areas has renewed the interest in indoor residual spraying (IRS) as a promising approach for Aedes-borne disease prevention. While IRS has ... -
Estimating absolute indoor density of Aedes aegypti (Stegomyia) using removal sampling
Quantifcation of adult Aedes aegypti abundance indoors has relied on estimates of relative density (e.g. number of adults per unit of sampling or time), most commonly using traps or timed collections using aspirators. The ... -
Experimental evaluation of the impact of household aerolsolized insecticides on pyrethroid resistant Aedes aegypti
The extensive reliance on insecticides to control Aedes aegypti mosquitoes and disrupt transmission of dengue, chikungunya and Zika has fueled the emergence of widespread resistance to insecticides. Mismatch between the ... -
Field efficacy trials of aerial ultra-low-volume application of insecticides against caged Aedes aegypti in Mexico
We evaluated the efficacy of aerial ultra-low-volume (ULV) insecticide spraying in field bioassays with caged Aedes aegypti in May 2017 in Puerto Vallarta, Jalisco, Mexico. The insecticides tested included an organophosphate ... -
Fine-scale spatial and temporal dynamics of kdr haplotypes in Aedes aegypti from Mexico
As resistance to insecticides increases in disease vectors, it has become exceedingly important to monitor populations for susceptibility. Most studies of field populations of Aedes aegypti have largely characterized ... -
House screening with insecticide-treated netting provides sustained reductions in domestic populations of Aedes aegypti in Merida
There is a need for effective methods to control Aedes aegypti and prevent the transmission of dengue, chikungunya, yellow fever and Zika viruses. Insecticide treated screening (ITS) is a promising approach, particularly ... -
Spatial variation of insecticide resistance in the dengue vector Aedes aegypti presents unique vector control challenges
Dengue is a major public health problem in Mexico, where the use of chemical insecticides to control the principal dengue vector, Aedes aegypti, is widespread. Resistance to insecticides has been reported in multiple sites, ...
