Microencapsulation for improved mosquitoes' repellent efficacy of cotton fabrics

Abstract

In recent years, mosquitoes that can transfer viruses causing vector-borne diseases, such as dengue fever, chikungunya, Zika and West Nile virus have dramatically increased and reached Europe. In 2018, a higher number of 1503 human cases were reported in the EU/EEA and EU neighbouring countries. The current research was involved in the development of mosquito repellent cotton fabrics with natural essential oils and further improvement of mosquitoes repellent efficacy by microencapsulation of repellents on cotton Fabrics. The repellents efficacy for Anopheles spp. is calculated by using the results of WHO modified test method CTD/WHO PES/IC/96.1. Mosquito-repellency of the treated cotton fabrics against Aedes aegypti mosquito species were tested by using Y-tube Olfactometer. SEM images of treated cotton fabrics were also represented in this paper.
