Efficiency Comparison of Mosquito Repellents for Selecting Appropriate Products to Prevent Mosquitoe Bite

Abstract

Chemical control section, a part of National Institute of Health, Department of Medical Sciences, is the office providing bioefficacy testing services for household and public health insecticides in both pre- and post-marketing stages, including mosquito coil. Bioefficacy data of mosquito coils against Aedes aegypti were collected for six years (from 2011 to 2017) with a total of 150 samples. The results showed that all formu­lations contained Pyrethroid as their active ingredients, particularly d-Allethrin. While 0.05% transfluthrin mosquito coil was found to be highly effective against Ae. aegypti giving the fastest knockdown with 1 min­utes 29 second and 100% mortality of Ae. aegypti.
