Results of the larval surveys of the control and treated villages conducted during the pre-intervention and intervention periods. a The prevalence rate of Ae. aegypti species in pre-intervention period (October 2017) in the control village (23/57) and the treated village (17/84), followed by intervention periods, in February 2018 (16/75, 4/143), in July 2018 (31/102, 6/146), in September 2018 (19/82, 0/140), and in July 2019 (24/81, 3/106). b The prevalence rate of Ae. albopictus species in pre-intervention period (October 2017) in the control village (13/57) and the treated village (11/84), followed by intervention periods, in February 2018 (6/75, 2/143), in July 2018 (15/102, 32/146), in September 2018 (7/82, 9/140), and in July 2019 (18/81, 19/106). P values were calculated using Fisher’s exact test (in control village and treated village: pre-intervention in October 2017 vs. intervention periods *P < 0.05 and ***P < 0.001)
