          Abstract

          Se presentó un estudio descriptivo sobre las especies de culícidos presentes en los hábitats de los primeros casos y sospechosos de virus del Nilo Occidental en Cuba y el estado de sus principales fuentes de cría. Los muestreos se realizaron a un radio de 1 000 m de las moradas de 2 casos positivos y 19 sospechosos. Se identificaron 16 especies de culícidos de las cuales 6 están vinculadas a la transmisión de la entidad en Norteamérica, predominando Culex quinquefasciatus Say, 1823 y Culex nigripalpus Theobald, 1901. Entre los principales factores de riesgo se consideraron el inadecuado estado ambiental de criaderos permanentes (fosas, zanjas y cañadas), así como la existencia de depósitos destinados al consumo de agua no protegidos en la vivienda y el peridomicilio.

          A descriptive study on Culicidae species present in the habitats of the first positive cases and suspected cases of being affected by West Nile virus in Cuba and the conditions of its main breeding sources was presented. The samplings were taken in a radius of 1 000 meters from the houses of 2 positive cases and 19 suspected cases. Sixteen Culicidae species of which 6 are associated to the virus transmission in North America, mainly Culex quinquefasciatus Say, 1023 and Culex nigripalpus Theobald, 1901. Among the fundamental risk factors are the inadequate environmental condition of permanent breeding sites (pits, ditches and streams) as well as unprotected water tanks inside the house and in the perimeter of the house.

              Aedes aegypti infestation characteristics in several Caribbean countries and implications for integrated community-based control.

              Periodic larval surveys for Aedes aegypti were conducted in 11 Caribbean countries between 1983 and 1989. On average, there were 24 potential larval habitats per house including 4.9 which held water at the time of examination. Breteau indices for the various islands ranged from 34.7 to 121.6. In descending order of importance, water storage drums, house plants, buckets, used tires and miscellaneous small discarded containers accounted for 84% of all foci. Highest rates of infestation were found in tires (38.4%) and drums (33.8%). For the development of integrated community-based vector control programs, not only should consideration be given to the larval ecology of Ae. aegypti, but also to the sociological significance of the various container habitats and the selection of control strategies most appropriate for their management.
