Statistical Framework Used To Assess Mosquito Control Programs

A new statistical framework that have been using to assess mosquito control programs; but over broad time and space scales;Effective methods of controlling mosquito populations are needed to help lower the worldwide burden of mosquito borne diseases; including Zika, chikungunya, and dengue.

But for identifying the dose response curve between neighborhood level; but some spraying interventions and neighborhood Aeaegypti population abundances. To achieve in the face of substantial spatio temporal variation in mosquito population abundances and imperfectly sampled mosquito populations; we had to achieve our second goal; to develop a mosquito abundance-modeling framework.

Mosquito Control Programs

The mosquito Aedes aegypti is the main vector for numerous viruses; and control efforts are underway for many of the associated mosquito borne diseases. By applying our model to Iquitos; Peru, researcher identifying interpret able relationships between meteorological covariates and mosquito populations, as well as, site specific spatial variation; with some regions of the city appearing to over- or under produce mosquitoes consistently through the study period.

Factors that are rarely measuring; such as maximum wind speed, finding some to be strongly significant and should be considered for future entomological studies on Aeaegypti abundance. Previous analysis also found that winds may influence the spatial patterns of dengue transmission in Iquitos. Aedes aegypti have cryptic landing and larval development sites.

Ae. aegypti Abundance

Aspiration, even when conducted by a team of trained professionals; is an imperfect method to fully survey a house. Our Aeaegypti abundance estimates for Iquitos under represent the true number of mosquitoes within the city.The researchers found that with complete neighborhood coverage of insecticide; Ae. aegypti abundance decreased by an average of 67% in the treated neighborhood; aegypti mosquitoes captured in the North and the South of Iquitos than in the city center.

Spatially, the coefficient of variation exhibited considerably larger variation than temporally; but with values ranging from 1.2 to 17.1; with the largest values in the Tupac Amaru region of western Iquitos. Over 100 mosquitoes were collected from a single home twice in this zone; and more than ten mosquitoes were collected from a single home 13 times. Even with the large number of visits to this zone; these extremely large collections (and others) indicated a high level of over dispersion.
