Abundancia proporcional de culícidos en el ecosistema urbano de Ciudad de La Habana / Proportional abundance of culicidae in the urban ecosystem of Havana City

RESUMO

Proportional abundance of the four most common mosquito species was determined in six types of breeding places located in Plaza de la Revolución municipality, City of Havana from 1993-1996. Culex quinquifasciatus exhibited values over 0.60 except in tyres and larval traps in 1993 and 1994 whereas Aedes mediovittatus showed similar values in low tanks and artificial reservoirs in 1994 (0.43 and 0.56 respectively). It was also observed that this species prefers larval traps. Aedes aegypti and Culex migripaplpus had the lowest abundance values (0.01). These results allowed us to state that there is a sort of shared use by these species of those reservoirs where they breed and that Culex quinquefasciatus is the predominant one.
