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.

Highlights

  • A recent outbreak of West Nile virus in Central Europe (2018) demonstrates the need for increased research on repellents against invasive mosquitoes which carry the West Nile virus

  • 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

  • Cotton samples used in the current research were conventionally treated with new natural mosquito repellents: Immortelle essential oil and micro- to nano- vibroactivated zeolite

Summary

Introduction

A recent outbreak of West Nile virus in Central Europe (2018) demonstrates the need for increased research on repellents against invasive mosquitoes which carry the West Nile virus. Many infectious diseases are vector-borne including malaria, Zika virus, dengue and chikungunya virus, West Nile virus and plague, all of which are spread via the bites of infected mosquitoes, and are prevalent in subtropical regions to which South European countries belong. During the last 15 years Aedes albopictus (Asian tiger mosquito) was introduced into Europe and has spread to several countries, which increases the possibility of its transmission [3,4].
