The status of Simulium oyapockense and S.limbatum as vectors of human onchocerciasis in Brazilian Amazonia
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 studyExpand

The interdependence of B chromosomes, nucleolar organizer expression, and larval development in the blackfly species Cnephia dacotensis and Cnephia ornithophilia (Diptera: Simuliidae)
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 isExpand

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 hybridizationExpand

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 isExpand
