Introduction. The spread of dengue is attributed to the expanding geographic distribution of the four serotypes of dengue and the spread of its mosquito vectors, Aedes aegypti and Aedes albopictus. Ae. aegypti reinfestations began in the 90s in several provinces of Cuba along with the introduction of Ae. albopictus in 1995. Objective. Determine the spatial and temporal distribution of Ae. aegypti and Ae. albopictus breeding sites in Pinar del Río province, Cuba from 2003-2010. Materials and Methods. Larval collections were made throughout the province, following the methodology of the Ae. aegypti control program. Results. Ae. aegypti presence increased in 13 (92.8%) of all municipalities in the province in 2010, while Ae. albopictus was found in 100% of the municipalities in the province in 2008. Both species were distributed in significant quantities across municipalities located in the south-central part of the province, in areas with: grassy plains, major urbanization, and areas with main transport routes. Increased mosquito presences were found from July to October, coinciding with higher positive values in standing water in ground level tanks and in small artificial containers, although at different rates. Ae. albopictus showed a preference for breeding in larvae traps. Ae. aegypti and Ae. albopictus showed both low association between them and with other species of mosquitoes. Conclusion. Ae. albopictus populations are expected to become endemic in the province, replacing Ae. Aegypti, in a large part of the province, requiring continuing studies by the researchers.

Introduction: malaria is considered to be a serious health problem in Haiti, mainly in the rural zones of the coastal area located at 600 m above the sea level, particularly shallow zones with rice crops., Objective: to describe the actions taken in four sites of two Haitian departments to face the rise of the number of malarial cases., Methods: the advisory work was carried out in three communities located in the West department and one in Nippes department in April 2010. Fever screenings along with sample-taking for thick smear test were performed as well as anti-vector activities including search for breeding sites and thermal treatment in the house and out of it., Results: it was confirmed in this thick smear test that not all the persons presenting with febrile symptoms suffered malaria since low positive values to this disease were obtained. During this study, only Plasmodium falciparum was diagnosed. Out of the 46 breeding sites, 26 were positive to Anopheles albimanus. The impact of insecticidal treatment could not be assessed since the areas did not have preliminary data on this respect., Conclusions: these results provide the malaria control program with pieces of knowledge about the distribution and control of vectors in addition to emphasizing the need of making an updated stratification of the incidence of the disease that comprises all the aspects of the malaria control program in Haiti.

Introduction: the earthquake occurred in Haiti in January 2010 led to the worsening of the hygienic, sanitary and environmental conditions and increased the number of breeding sites for disease-borne vectors in the country., Objectives: to report the first results of the entomological surveillance set by the Cuban advisory group in Haiti after the earthquake., Methods: the work was carried out in 7 sites located in West department, one of the ten departments of the country; larval sampling was conducted in reservoirs and natural breeding sites based on the methodologies for both. The sampling was weekly in the May-October period in 2010., Results: twelve mosquito species were reported in the West department as well as the presence of Triatoma rubrofasciata. The fundamental breeding sites of the three most important mosquito species were identified including Aedes aegypti with water tanks followed by worn car rubbers and small artificial deposits, Anopheles albimanus in rice fields, animal footprints and coastal swampy plains, and Culex quinquefasciatus, one lymphatic phylarosis-borne vector still existing in Haiti, in drains and waste water ditches., Conclusions: these results are the first ones from this surveillance program after the earthquake and represent valuable information for the decision-making at the time of designing a control program to face the occurrence of any epidemics in which these insect vectors might be involved in this department.
