Background The combination of Wolbachia -based incompatible insect technique (IIT) and radiation-based sterile (SIT) can be used for population suppression Aedes aegypti . Our main objective was to evaluate whether open-field mass-releases w AlbB-infected Ae males, as part an Integrated Vector Management (IVM) plan led by the Mexican Ministry Health, could suppress natural populations in urbanized settings south Mexico. Methodology/Principal findings We implemented a controlled...
Understanding how emerging infectious diseases spread within and between countries is essential to contain future pandemics. Spread new areas requires connectivity one or more sources a suitable local environment, but these two factors interact at different stages of disease emergence remains largely unknown. Further, no analytical framework exists examine their roles. Here we develop dynamic modelling approach for that explicitly models both via human movement environmental suitability...
The markedly anthropophilic and endophilic behaviors of Aedes aegypti (L.) make it a very efficient vector dengue, chikungunya, Zika viruses.

The operational impact of deltamethrin resistance on the efficacy indoor insecticide applications to control Aedes aegypti was evaluated in Merida, Mexico. A randomized controlled trial quantified residual spraying (IRS) against adult Ae. houses treated with either (to which local expressed a high degree resistance) or bendiocarb were fully susceptible) as compared untreated houses. All infestation indices during 3 months post-spraying significantly lower (odds ratio <0.75; incidence rate <...
Zika virus (ZIKV) is a mosquito-borne pathogen, and Aedes aegypti has been identified as the main vector of disease. Other mosquito species in Culex genera have suggested to potential for being competent vectors based on experimental exposition mosquitoes an infectious blood meal containing ZIKV. Here, we report isolation cell culture ZIKV obtained from different body parts wild-caught female (Ae. aegypti, Ae. vexans, Cx. quinquefasciatus, coronator, tarsalis) whole male quinquefasciatus)...
Since past century, vector-borne diseases have been a major public health concern in several states of Mexico. However, Mexico City continues to be free endemic mosquito-borne viral diseases. The city is the most important politic and economic state one Latin America. Its subtropical highland climate high elevation (2240 masl) had historically made occurrence Aedes species unlikely. presence other potential disease vectors (Culex spp, Culiseta spp), current intermittent introductions...
Challenges in maintaining high effectiveness of classic vector control urban areas has renewed the interest indoor residual spraying (IRS) as a promising approach for Aedes-borne disease prevention. While IRS many benefits, application time and intrusive applications make its scalability difficult. Modifying to account Ae. aegypti resting behavior, named targeted (TIRS, walls below 1.5 m under furniture) can reduce time; however, an untested assumption is that modifications will not...
Background There is a need for effective methods to control Aedes aegypti and prevent the transmission of dengue, chikungunya, yellow fever Zika viruses.

Methodology/Principal findings A cluster-randomised controlled trial evaluated entomological efficacy ITS based intervention, which consisted installation pyrethroid-impregnated long-lasting insecticide-treated...
Abstract Background Current urban vector control strategies have failed to contain dengue epidemics and prevent the global expansion of Aedes -borne viruses (ABVs: dengue, chikungunya, Zika). Part challenge in sustaining effective ABV emerges from paucity evidence regarding epidemiological impact any method. A strategy for which there is limited targeted indoor residual spraying (TIRS). TIRS a modification classic malaria that accounts aegypti resting behavior by applying insecticides on...
Rocky Mountain spotted fever (RMSF) is an ongoing public health crisis in Mexico, particularly states bordering the United States. The national highest incidence and mortality of RMSF occur this region, resulting a case-fatality rate that ranges annually between 10% 50%, primarily affecting vulnerable groups such as children, elderly adults, persons living poverty. Multiple biological, environmental, social determinants can explain its growing presence throughout country how it challenges...
The Asian tiger mosquito, Aedes albopictus (Skuse) (Diptera: Culicidae), is an invasive species and a vector of numerous human pathogens, including chikungunya, dengue, yellow fever, Zika viruses. This mosquito had been reported from 36 geographic locations in Mexico by 2005, increasing to 101 2010 501 (spanning 16 states) 2016. Here we modeled the occupied niche for Ae. characterize environmental conditions related its presence, generate updated suitability maps. predictors with greatest...
We report on the results of an entomovirological surveillance system Aedes populations performed by Ministry Health central state San Luis Potosí, Mexico. Indoor adult aegypti and albopictus pools collected at Martín, Tamazunchale, Ciudad Valles, Metlapa, Ebano, Tamuin Axtla during dry season 2016 were examined for presence dengue (DENV), chikungunya (CHIKV) Zika (ZIKV) viruses using real-time PCR.
