CHAPTER 3.9 226 Haiti Introduction Geographical context Haiti is a mountainous country; 40% of its territory is located at altitudes above 490 m. The mountain ranges alternate with fertile valleys, the largest being the Plaine du Nord. Annual rainfall varies from 500 in the north-west to 2500 mm in the eastern/southern highlands. Agriculture accounts for one-third of the gross domestic product but subsistence farming predominates. Maize (Zea mays L.; 250,000 ha), sorghum (Sorghum bicolor [L.] Moench; 160,000 ha), common bean (Phaseolus vulgaris L.; 100,000 ha) are the main staples, with rice (Oryza sativa L.) and sweetpotato (Ipomoea batatas [L.] Lam.) also being important components of the Haitian diet. However, most of the food consumed in Haiti has to be imported. Coffee (Coffea arabica L.) is the main export crop (145,000 ha), followed by sugarcane (Saccharum officinarum L.), sisal (Agave sisalana Perrine ex Engelm.) and cacao (Theobroma cacao L.). French-Creole is spoken by 90% of the population and only 10% speak French.

Whiteflies and Whitefly-borne Viruses in the Tropics Francisco Morales*, Jackson Donis** and Emmanuel Prophete** crops have become increasingly important in Haiti, mainly as an extension of the agricultural export business in the Dominican Republic. Figure 1 shows the main agricultural regions affected by whitefly-transmitted begomoviruses. The emergence of Bemisia tabaci as a pest and virus vector The whitefly Bemisia tabaci was first regarded as a serious pest in Haiti, in the early 1980s. Common bean, tomato (Lycopersicon esculentum Mill.), eggplant (Solanum melongena L.), pepper (Capsicum spp. L.), cowpea (Vigna unguiculata [L.] Walp.) and lima bean (Phaseolus lunatus L. var. lunatus) are the main crops affected by this insect pest (Donis and Prophete, 1997). As a vector, B. tabaci already had been observed to transmit Bean golden yellow mosaic virus (BGYMV) in 1978 (Balthazar, 1978). Advances in Biological Research The main agricultural areas of Haiti were surveyed and plant samples analysed to determine the importance of whiteflies and whitefly-borne viruses. Table 1 shows the different regions visited and the results obtained from the tests practiced with samples collected. Of whitefly-transmitted
