WHO Pesticide Evaluation Scheme (WHOPES)

Equipment and application

Equipment for vector control – Specification guidelines, revised version 2010

The specification guidelines contained in this document are intended to assist national authorities in selecting quality equipment for vector control.

WHO no longer tests pesticide application equipment, for compliance with WHO specifications, at the request of industry. It will be the responsibility of national programmes to request for warranty on the equipment and any certification required regarding materials used in the construction of the equipment. It will also be their responsibility to arrange for a quality control test with a recognized laboratory (e.g. a WHO Collaborating Centre) equipped to evaluate pesticide application equipment. This evaluation by national authorities should also include equipment that has previously received WHO certification for compliance with WHO specifications. Such certificates are no longer valid and should no longer be used.

Reference to the name of WHO and its recommendations by manufacturers, suppliers or any other parties for commercial or promotional purposes is not authorized.

Indoor application of residual sprays – Third edition

Indoor residual spraying is extensively used, especially for malaria and Chagas disease vector control. However, vector control programmes frequently lack well-trained field staff to apply the insecticides and to maintain the application equipment. With good skills and quality application equipment, hazards to human health and the environment, as well as financial losses, can be avoided.

The WHOPES Manual for indoor residual spraying – application of residual sprays for vector control is intended to serve as a “model” for developing relevant training materials and procedures at country level, to ensure safe and effective use of insecticides in vector control programmes.

Space spray application of insecticides

Space spraying provides a rapid method of controlling flying insect pests or vectors. However, it may not be an appropriate and economical method of control for all vectors/pests and situations.

The WHOPES manual Space spray application of insecticides for vector and public health pest control – a practitioner’s guide provides a brief description of the main types of space spray equipment as well as the operational guidelines for space spray application of insecticides.

Insecticide treatment of mosquito nets

A more simplified approach to insecticide treatment of mosquito nets (ITNs) is based on experiences in the field over recent years and a better understanding of insecticides and their interaction with netting materials. The document is designed for use by national control programmes, dipping centres, mobile teams, village health workers, nongovernmental organizations, bednet and insecticide manufacturers and others who promote the judicious use of ITNs.
The approach can be found in Instructions for treatment and use of insecticide-treated mosquito nets, Geneva, World Health Organization.
