Enhanced knowledge was gained on the biology and ecology of cocoa pollination and midge management. Research was conducted in the field and laboratories in Trinidad and Tobago, and Jamaica. A total of 77 persons were trained in pollination biology and midge rearing, suction trap technology and devices, and data collection and analysis. A multi-farm baseline survey enabled the identification of different strains of midges and the separation of those from the main pollinator, in addition to other insects present in the cocoa field. Major achievements included field media manipulation, midge culturing and rearing, synthesis of cocoa floral odours and simulation of adverse weather conditions. An original contribution to the existing body of knowledge was made by documenting the cocoa flower phenology and the complete cocoa crop reproductive cycle.
