Cytotaxonomy of the Simulium damnosum complex from central and northeastern Tanzania.
A cytotaxonomic study of the medically important insect vector, Simulium damnosum s.l., revealed the presence of seven and possibly eight distinct taxa from central and northeastern Tanzania. Larval… Expand
A cytogenetic analysis of the Simulium ochraceum species complex (Diptera: Simuliidae) in Central America.
A cytobiotaxonomic study of the medically important insect vector Simulium ochraceum s.l. revealed two sibling species and one cytotype from various endemic and nonendemic zones of human… Expand

Abstract. In an attempt to explain trie current distribution of onchocerciasis in the forests of northern Brazil (Moraes etal., 1979,1986), and its potential for dispersal to other areas, this study… Expand

This paper presents an overview of advances in cytological research on the biosystematics of vector simuliid complexes in the areas of identification, age grading, and the evolution of resistance in… Expand
Localization of ribosomal DNA in Rhagoletis pomonella (Diptera: Tephritidae) by in situ hybridization
The ribosomal DNA (rDNA) of Rhagoletis pomonella was localized within both salivary gland polytene chromosomes and somatic cell mitotic chromosomes by in situ hybridization using the heterospecific… Expand

The taxonomic status of three Amazonian simuliid species, Simulium guianese Wise, S. oyapockense Floch & Abonnenc and S. yarzabali Ramirez Perez is reviewed. Simulium cuasisanguineum Ramirez Perez,… Expand
The interdependence of B chromosomes, nucleolar organizer expression, and larval development in the blackfly species Cnephia dacotensis and Cnephia ornithophilia (Diptera: Simuliidae)
- W. Procunier
- 1 November 1982
A primary relationship is found between nucleolar organizer (NO) expression (puffing) of the A complement and numbers of B chromosomes in Cnephia dacotensis, such that a high incidence of B's is… Expand
Physical mapping of the Esterase-6 locus of Drosophila melanogaster
The Esterase-6 gene locus of Drosophila melanogaster although well-characterized, has not been definitly mapped by in situ hybridization. In this paper, a high resolution in situ hybridization… Expand
Development of a method for the cytological identification of man-biting sibling species within the Simulium damnosum complex.
A method is described for the preparation of adult Malpighian tubule polytene chromosomes from members of the Simulium damnosum complex. This method was used to show that the banding pattern is… Expand
