Overview

Larval source management (LSM) refers to the targeted management of mosquito breeding sites, with the objective to reduce the number of mosquito larvae and pupae. When appropriately used, LSM can contribute to reducing the numbers of both indoor and out-door biting mosquitoes, and – in malaria elimination phase – it can be a useful addition to programme tools to reduce the mosquito population in remaining malaria ‘hotspots’.

This operational manual has been designed primarily for National Malaria Control Programmes as well as field personnel. It will also be of practical use to specialists working on public health vector control, and malaria programme specialists working with bilateral donors, funders and implementation partners. It has been written by senior public health experts of the malaria vector control community under the guidance of the WHO Global Malaria Programme.

The manual’s three main chapters provide guidance on:

  • the selection of larval control interventions,
  • the planning and management of larval control programmes, and
  • detailed guidance on conducting these programmes.

The manual also contains a list of WHOPES-recommended formulations, standard operating procedures for larviciding, as well as a number of country case studies.
