| Abstract: | The leaf-mining hispidPromecotheca cumingi Baly, was first recorded as a pest on coconut in Sri lanka in October 1970. Its possible mode of entry and spread from the point of first occurrence are discussed. An account is given of the life-cycle, rate of multiplication, host plants and damage under Sri Lanka conditions. The spectacular success achieved in controlling the pest, which was spread over about 8,000 hectares, using the biological method, the techniques adopted for breeding and release of exotic parasites and the follow-up surveys to ascertain activity of the introduced parasites are discussed in detail. A brief account of the cost/benefit analysis is also given. |
