Interspecific relationship between Aedes albopictus (Diptera: Culicidae) and Culicidae species in Havana, Cuba.

Abstract

Introduction. Aedes aegypti and Aedes albopictus recognized dengue vectors are considered invasive species that are widely distributed in tropical and temperate regions of the planet. The current distribution of the two Aedes mosquitoes overlap and are affected by interspecific larval competition in their container habitats. Objective. To determine the interspecific relationship of Ae. albopictus with mosquitoes communities in Havana province in Cuba in two time periods, 1995-1999 and 2010-2012. Methods. Annual records of mosquito larval samples from Entomology Laboratory Havana province were used for this study. Results. Coexistence between Ae. albopictus and Ae. aegypti as well as with Culex quinquefasciatus was demonstrated favored in the case of the first by strong insecticide pressure is subject Ae. aegypti throughout the year and the second by be considered an opportunistic species and the physiological tolerance to insecticides reported for it, whereas replacement of Ae. mediovittatus by Ae. albopictus was observed. Conclusions. Our study demonstrated the coexistence between Ae. albopictus and Ae. aegypti in Havana province favored by the rainy-dry seasonal cycle present in Cuba, the availability of existing breeding sites product sanitation deficiencies and problems in the water supply, in addition to the permanent control of Ae. aegypti that only influencing populations of Ae. albopictus partially.
