An island-wide house survey was conducted in January 2002 to determine the geographicdistribution, container profile, and population density of the Aedes aegypti in Tobago, West Indies. The resultsshowed the Ae. aegypti infestation levels were significantly different (P > 0.01) among the 4 districts, withgreater infestation levels (P > 0.01) observed in the Northem and Windward districts than in the Central andLeeward disricts. From the 50 towns in Tobago, houses were found positive in Delaford (21), Argyle (18), andGoodwood (14), representing 42.l% of the total number of positive houses in the Windward district (3,971houses); Parlatuvier (15), Whim (14), Castara (12), and Bloody Bay (12), representing62.3Vo of the total numberof positive houses in the Northern district (3,087 houses); Calderhall (12), Mason Hall (11), and GovemmentHouse (10), representing 46.5% of the total number of positive houses in the Central district (4,706 houses);and Lambeau (10), Bucco (6), and Bethel (6), representing 53.7Va of the total number of positive houses in theLeeward district (3,175 houses). The majority (66 or 63.5%) of dengue cases occurred in the Central districtwhere the Breteau indices ranged from 7.1 to 44.0 (mean = 16.6). These results suggest that a more systematicand sustained vector control program that uses both biological and chemical control methods should be adoptedto reduce Ae. aegypti populations to below dengue transmission thresholds.
