dispersal and oviposition of laboratory-reared gravid females of toxorhynchites moctezuma in an arid urban area of sonora, mexico.dengue is a serious public health problem worldwide. biological control of its vector, aedes aegypti, remains a feasible option in light of increasing urbanization and insecticide resistance. we studied the dispersal and oviposition activity of toxorhynchites moctezuma in a dengue-endemic urban area in ssonora, mexico, to provide information about the potential of toxorhynchites as a control agent for ae. aegypti in arid areas. we released 210 and 100 laboratory-reared gravid females of tx. moct ...200920099587
microclimate and human factors in the divergent ecology of aedes aegypti along the arizona, u.s./sonora, mx border.this study examined the association of human and environmental factors with the presence of aedes aegypti, the vector for dengue fever and yellow fever viruses, in a desert region in the southwest united states and northwest mexico. sixty-eight sites were longitudinally surveyed along the united states-mexico border in tucson, az, nogales, az, and nogales, sonora during a 3-year period. aedes aegypti presence or absence at each site was measured three times per year using standard oviposition tr ...201020232228
aedes aegypti (diptera: culicidae) longevity and differential emergence of dengue fever in two cities in sonora, mexico.dengue virus, primarily transmitted by the aedes aegypti (l.) mosquito, has rapidly expanded in geographic extent over the past several decades. in some areas, however, dengue fever has not emerged despite established ae. aegypti populations. the reasons for this are unclear and have sometimes been attributed to socio-economic differences. in 2013 we compared ae. aegypti adult density and population age structure between two cities in sonora, mexico: hermosillo, which has regular seasonal dengue ...201728082648
spatio-temporal and neighborhood characteristics of two dengue outbreaks in two arid cities of mexico.little is currently known about the spatial-temporal dynamics of dengue epidemics in arid areas. this study assesses dengue outbreaks that occurred in two arid cities of mexico, hermosillo and navojoa, located in northern state of sonora. laboratory confirmed dengue cases from hermosillo (n=2730) and navojoa (n=493) were geocoded by residence and assigned neighborhood-level characteristics from the 2010 mexican census. kernel density and space-time cluster analysis was performed to detect high d ...201728062233
binational dengue outbreak along the united states-mexico border - yuma county, arizona, and sonora, mexico, 2014.dengue is an acute febrile illness caused by any of four dengue virus types (denv-1-4). denvs are transmitted by mosquitos of the genus aedes (1) and are endemic throughout the tropics (2). in 2010, an estimated 390 million denv infections occurred worldwide (2). during 2007-2013, a total of three to 10 dengue cases were reported annually in arizona and all were travel-associated. during september-december 2014, coincident with a dengue outbreak in sonora, mexico, 93 travel-associated dengue cas ...201627196619
