Seasonal and Geographical Variation of Dengue Vectors in Narathiwat, South Thailand

Figure 3

Comparisons of the abundance of Ae. aegypti and Ae. albopictus in each container type by season. The abundance of Aedes vectors was presented by mean larva numbers (±2 SE) of Ae. aegypti (a) and Ae. albopictus (b) as denoted by error bars. Only the outdoor distributions of Aedes larva numbers in any key containers were further analyzed by the independent observations between two seasons in two study settings. In the urban-rural gradient, the equal distributions of Aedes larvae independently observed between seasons were tested using the Mann-Whitney test; the only two-independent samples that provided statistically significance () are shown.
