Abstract

SUAREZ DELGADO, Silvia et al. Macrocyclops albidus (Copepoda: Cyclopidae): a new alternative for the control of mosquito larvae in Cuba. Rev Cubana Med Trop [online]. 2005, vol.57, n.3. ISSN 0375-0760.

The cyclopoid copepod Macrocyclops albidus was evaluated as a biological control agent of Aedes aegypti and Culex quinquefasciatus larvae, culicides that frequently live in  containers  of domestic use in urban zones. The experiments were made under controlled laboratory conditions. Plastic containers with 5 L of dechlorinated water and 3 g of dry leaves were used. 2 densities of copepods and 3 combinations of larvae densities were added. 5 replicas were made. The count of the suviving larvae and the recovered copepods was made 6 days after the beginning of the experiment. It was observed a marked reduction of the larval population of mosquitoes in all the treatments with copepods. It was stressed their preference for the Ae. aegypti larvae that was not affected by the presence of  Cx. quinquefasciatus larvae. The copepods showed a high survival in all the assayed variants. It was over 100 % when they were added in the lowest density.
