New IPM strategies for the Caribbean

The development of new integrated pest management (IPM) strategies was the subject of a CTA seminar held in the Dominican Republic in November 1993. Participants assessed research on modern, integrated approaches to the management of the most serious pests of the crops of the small-scale Caribbean farmer, and they considered some of the alternative strategies that farmers may be able to adopt in the future. The workshop focused largely on the management of thrips (Thrips palm'), whiteflies (Bemisia tabaci) and aphids (particularly Toxoptera citricidus) and the diseases they carry, including citrus tristeza virus. These pests are posing great threats to the liveli-hoods of small Caribbean farmers who produce citrus and vegetable, particularly tomato crops. The meeting identified an impressive number of potential components of an IPM approach on which new strategies could be based. They included scouting methodologies to decrease the number of pesticide applications needed to achieve adequate control; the adoption of resistant crop varieties; improved crop sanitation; the use of insect growth regulators; the use of natural insecticides; new spray technologies; the adoption of new cultural practices; the use of more selective pesticides; the creation of refuge habitats; and the introduction and encouragement of parasites, predators and pathogens of the various crop pests and diseases. Participants recognized that the region needs a 'driving force' for the implementation of IPM, and that efforts to promote IPM must be more sharply focused and better coordinated. Educational campaigns could help to change attitudes and practices. Strong governmental support is needed for better pesticide management and the adoption of IPM strategies. Finally, quarantine procedures need strengthening throughout the region.The development of new integrated pest management (IPM) strategies was the subject of a CTA seminar held in the Dominican Republic in November 199
