Tipificación de hábitats de Aedes albopictus en Cuba y su asociación con otras especies de culícidos, 1995-1998 / Typing habitats of Aedes albopictus in Cuba and their association with other species of Culicidae, 1995-1998

A typing of the habitats of Aedes albopictus in Cuba was made after its detection in 1995. It was observed in suburban areas of the Boyeros Municipality, in Havana City, where a study was conducted from October, 1995, to July, 1998. Most of the positive repositories were found outside the houses. Tins, tires, trees and plants were the places preferred for its breeding. It was found in the breeding places associated with Aedes mediovittatus and Culex quinquefasciatus, dominant species in these places. It was also observed a trend towards an increase of the number of repositories colonized only by the species under study. Reference was made to the phenomenon of competence between this species and the indigenous species present in such places.

Sucesión ecológica de las especies de mosquitos en el municipio Boyeros, Ciudad de La Habana 1994-1996 / The ecological succession of mosquito species in the town of Boyeros, Ciudad de la Habana 1994-1996

An analysis was made on the incidence of Culicidae in Boyeros municipality, City of Havana from 1994 to 1996 based on the requirements of the national program for eradication of Aedes aegypti. A total of 13 species was detected in which Aedes mediovittatus predominated during 3 years of study, followed by Culex quinquefasciatus whereas for the first time Aedes albopictus species was found in the territory. People's Councils Wajay, Santiago de las Vegas and Armada exhibited the highest values of infestation by Culicidae in the municipality, therefore, they required that anti-Aedes program, operators paid more attention to this situation. It was found that depots preferred by Culicidae for breeding were larval traps followed by low tanks in 1994 and 1995 and by other reservoirs in 1996. A mediovittatus preferred larval traps whereas Cx. quinquefasciatus preferred low tanks except in 1996 when this species was mostly found in other tanks. 93 of all test-positive reservoirs found were colonized by only one species, whereas 7 presented larvae from 2 species or more. A. mediovittatus and C. quinquefasciatus were the most related, above all in low tanks.

Vigilancia entomológica de Aedes (S) aegypti y otros culícidos en Ciudad de La Habana, Cuba 1991-1996 / Entomological surveillance over Aedes (S) aegypti and other culicids in Ciudad de La Habana, Cuba 1991-1996

The results of the entomologic surveillance carried out from 1991 to 1996 in Boyeros municipality, City of Havana within the Program for Eradication of Aedes aegypti were analyzed. Data on mosquitoes fauna collected in the municipality by various sampling methods, larval survey, human bait, capture at rest and larval traps. Culex quinquefasciatus, Aedes mediovittatus and Aedes aegypti species were the most found by the different methods. It was proved that water tanks, man-made deposits, other kinds of tanks and low tanks were the most exploited resources by mosquitoes for their breeding in this municipality whereas larval surveys were the most sensitive method for detecting species since it contributed a greater variety of species. Reference is made to the search for a mechanism that help estimate adult populations from larval indices provided by surveys and the method of capture at rest is stressed as the most sensitive method for adult mosquitoes, particularly for dengue vector within the surveillance system aimed at this species.
