Differences in the preference for water types among mosquito larvae species in two villages. a Prevalence rate in the control village for water in daily use (number of infestation by Ae. aegypti, Ae. albopictus, and Culex spp., respectively 70, 19, 12; n = 272) and stagnant water (19, 22, 12; n = 44) that was obtained in the pre-intervention period (October 2017) and intervention periods (February, July, and September 2018) were used to analyze. b Prevalence rate in the treated village for water in daily use (6, 28, 6; n = 396) and stagnant water (1, 15, 11; n = 33) obtained during intervention periods (February, July, and September 2018) was used to analyze. The comparison showed that Ae. albopictus strongly preferred stagnant water, while Ae. aegypti did not prefer stagnant water as strongly as Ae. albopictus. P values were calculated using Fisher’s exact test (water in daily use vs. stagnant water: *P < 0.05, ***P < 0.001). The grey columns indicated water in daily use and the black columns indicated stagnant water
