RESUMO
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.

It is made a comparative analysis of the behaviour of the Aedes aegypti eradication program in two municipalities of Havana City with different characteristics during 1990-1992. The results show that in both municipalities the recipients with the highest positivity to mosquitoes were the following categories: other deposits, artificial deposits, and low tanks, followed by a second group that included tubs, tires, and larva tramps. The positivity of the larva tramps was observed in both municipalities and it is stressed their role in the stabilization of mosquitoes invading the urban ecosystem. There were 8 varieties of species at Plaza municipality, and 9 at the 10 de Octubre municipality. There are similar species in both municipalities.

An analysis of the relation among the quantity of focuses of Aedes aegypti, the rains and the temperatures in rainy and dry periods from 1982 to 1992 in 10 de Octubre municipe, at City of Havana, was carried out. No correlation was found between the number of focuses and the rains occurred in both seasons, and it was just the same between the number of focuses and temperatures. Thus, emphasis is made in the need for a strong surveillance along all year.
