Community participation is increasingly seen as a major component of successful control programmes against parasitic diseases. One of the strongest exponents of this has been the Vector Control Research Centre (VCRC) in Pondicherry, South India (Fig. 1), who have successfully motivated and involved village communities in vector control activities with considerable success against malaria and filariasis vectors. Their largest single programme, the Filariasis Control Demonstration Project in Pondicherry Town, has now been handed to the Pondicherry State Government, while the VCRC's work on malaria and filariasis control is now expanding throughout other parts of India. As this article shows, much has been learnt from these projects, not just about control techniques but also about education, administration and decision-making.
