WORLD HEALTH ORGANIZATION TECHNICAL REPORT SERIES. 1995; (857):i-vi, 1-91.In 1993, the World Health Organization (WHO) Study Group on Vector Control for Malaria and other Mosquito-Borne Diseases convened in Geneva to develop well-defined guidelines for implementing the vector control component of the Global Malaria Control Strategy. Goals and objectives of the control strategy, vector control, and the study group as well as those concerning use of the insecticide DDT are addressed in the meeting's published report. A review of the global status and trends in malaria and other mosquito-borne diseases follows. Malaria status and experiences, priorities, and trends in vector control in the various WHO regions are examined. One section reviews objectives of vector control, considerations in planning and implementation, selectivity and sustainability, information systems management, stratification of malarious areas by eco-epidemiological criteria, and priority geographical areas and risk groups. Indoor residual spraying, personal protection measures, larviciding and biological control, and environmental management are also discussed. The next section examines the role of vector control in malaria epidemics and drug-resistant malaria. Another section examines indicators of operational and entomological impact and of impact on disease and integrated use of control methods under the context of monitoring and evaluation of vector control efforts. Entomological parameters and techniques discussed include detection and monitoring of insecticide resistance, bioassays, adult density, resting indices, mosquito age and survival rates, human-vector contact, mosquito infection rates, entomological inoculation rate, and measurement of malaria transmission as well as choice of parameters and design for evaluating interventions. Other topics include the role of entomological services in malaria control, managerial aspects of malaria vector control and entomological services, comprehensive vector-borne disease control, capacity building, role of communities and other sectors in vector control, cost-effectiveness in vector control, research in vector control, and policy issues related to vector control.
