Results of a recent survey of the 3 species of Anopheles mosquitoes, Anopheles (Nyssorhynchus) aquasalis, Anopheles (Nyssorhynchus) argyritarsis, and Anopheles (Anopheles) pseudopunctipennis, on the island of Grenada are contrasted with the only other published survey of these species on Grenada, which was published in 1938. Results suggest that a significant change in the abundance and distrib...

Anopheles malefactor Dyar and Knab is elevated from synonymy with An. punctimacula Dyar and Knab, and both species are described and illustrated. Primary morphological differences in the adult, pupal, and larval stages are provided for the separation and recognition of these species. An. punctimacula occurs from Mexico to northern Colombia and Venezuela, whereas An. malefactor is restricted to ...

Malaria is still a primary health problem in Colombia. The locality of Tierradentro is situated in the municipality of Montelíbano, Córdoba, in the northwest of Colombia, and has one of the highest annual parasite index of malaria nationwide. However, the vectors involved in malaria transmission in this locality have not yet been identified. In this study, the local anthropophilic Anopheles com...

Metaphase karyotypes of 9 species of the Myzomyia Series show intra- and interspecific differences based on quantitative variation and distribution of constitutive heterochromatin in the sex chromosomes or the centromeric regions of the autosome pairs or both. Anopheles jeyporiensis and Anopheles aconitus each exhibit 4 forms of mitotic karyotypes, which may reflect interspecific differences wi...

A survey for larval and adult Anopheles mosquitoes was conducted in Toledo District of southern Belize during August-September 1992. We surveyed for larvae in 145 habitats and conducted paired indoor-outdoor collections of adult mosquitoes landing on humans at 6 houses. In 1940-41, Kumm and Ram reported Anopheles darlingi females to be the most common Anopheles mosquitoes inside houses and repo...

This report provides results of the first detailed examination of morphological abnormalities occurring in adults, pupae, and 4th-instar larvae of a sibling species complex within the family Culicidae. Aberrant and/or anomalous setae or structures are reported, along with their frequency of occurrence, for the 5 sibling species (Anopheles diluvialis, Anopheles inundatus, Anopheles maverlius, An...
