The Bionomics and Vector Competence of Anopheles Albimanus and Anopheles Vestitipennis in Southern Belize, Central America

Abstract

During an 18 month study period (1997-1998) in the Toledo District, southern Belize, a series of studies were undertaken to evaluate the vector competence of theAnopheles mosquitoes. At both Golden Stream and Rancho, the population densities of An. vestitipennis showed positive correlation with human cases of P. vivax. and tested positive for P. vivax 210 (MFIR of 0.01 and MFIR of 0.0004, respectively). Population densities of An. darlingi from Golden Stream showed a negative correlation with high numbers of malaria cases but also tested positive for P. vivax 210 (MFIR of 0.001). Population abundance of An. albimanus from Rancho showed a negative correlation with malaria transmission and was not found naturally infected with malaria parasites. The feeding preference study showed An. vestitipennis to prefer feeding on human blood while An. albimanus showed a strong tendency for feeding on cattle and non-human hosts.
