Abstract
Recently, as worldwide pandemic of dengue fever, researchers have attempted to predict the distribution of dengue vector mosquitoes. However, the earlier studies remained challenges in precisely understanding local prevalence of the vector mosquitos and its association with ambient environmental attributes. Here this study explored spatial and temporal oviposition patterns of the dengue vector mosquitos under heterogeneous meteorological, flooding, and land cover conditions using highly frequent data on the abundance of the dengue mosquito eggs observed throughout Metropolitan Manila. The abundance of the vector mosquito eggs (OI) tended to increase in the rainy season compared to the dry season. Spatial autocorrelation in the OI displayed a different trend depending on the seasons, suggesting that the spatial pattern of the oviposition of the vector mosquitoes are constrained by seasonally heterogeneous environmental conditions. The OI increased in response to increases in rainfall but in limited cases. In the residential area, the OI was higher than other land cover classifications.
