Guidelines for assessing the efficacy of insecticidal space sprays for control of the dengue vector: Aedes aegypti

Overview

This document has been prepared in response to a recommendation of the Informal Consultation on 'Strengthening Implementation of the Global Strategy for Dengue Fever/Dengue Haemorrhagic Fever Prevention and Control', held at WHO/HQ, Geneva, 18-20 October 1999. lt is intended to stimulate public health authorities to carry out entomological assessments of the impact of insecticidal space sprays on the main dengue vector, Aedes aegypti, and to guide them in that process.

WHO will be pleased to assist countries in adapting the guidelines to their local needs. National authorities are encouraged to share the results of such studies and to assist the Organization to further develop the regional and global strategies for dengue fever prevention and control.

A complementary WHO document, 'Space Spray Application of Insecticides for Vector and Public Health Pest Control', will be published in 2002. This document describes the operational procedures and considerations needed to ensure correct use and application of insecticidal space sprays.
