Evaluation of the efficacy of 20% IR3535^® with a sustained-release formulation and 25% DEET insect repellents against mosquitoes in a field setting in Ghana.

ABSTRACT:

Background

Personal protection with topical skin repellents has been advocated for use against vector-borne diseases. This study compared the efficacies of a 20% IR3535^® lotion with Staytec technology formulation and 25% DEET lotion in repelling mosquitoes in two rural communities in Ghana.

Methods

Mosquito biting densities were established at baseline and during the intervention using human landing collections (HLC). These were carried out overnight from 21:00-06:00 Greenwich Mean Time (GMT). Prior to the HLC, the exposed legs were treated with either a lotion of the 20% IR3535^® or 25% DEET (as test) at a rate of 1 g/600 cm², and 70% ethanol (as control). The sampling (HLC) was performed using the Latin square design. Mosquito species were i
