1841. Chinius junlianensis Leng 1987 (Diptera: Psychodidae): new morphological data. (Abstract)

Chinius junlianensis Leng 1987 (Diptera: Psychodidae): new morphological data. For the first time, dissection and microscopical examination of several specimens of Chinius junlianensis Leng 1987 have revealed the antennal and palpal formulae of both males and females of this species and the true morphology of the spermathecae in the females. The latter have smooth elongated reservoirs and a very long common duct, which matches the long genital filaments of the males. There are no setae

1842. The diel oviposition periodicity of Aedes aegypti (L.) (Diptera: Culicidae) in the laboratory: density disturbance. (Abstract)

The diel oviposition periodicity of Aedes aegypti (L.) (Diptera: Culicidae) in the laboratory: density disturbance. The diel oviposition periodicities of the LSHTM and Trinidad strains of Aedes aegypti were studied under laboratory conditions, using different mosquito densities in the cages and monitoring at 2-h intervals. With both strains, the peak in oviposition occurred earlier in the day when there was only one female in a test cage (16.00-18.00 hours) than when 25 or 500 females were held

1843. A molecular marker for the identification of Simulium squamosum (Diptera: Simuliidae). (Abstract)

A molecular marker for the identification of Simulium squamosum (Diptera: Simuliidae). All except one of the important groups of West African vectors of Onchocerca volvulus that lie within the Simulium damnosum complex can be distinguished from each other using morphological characteristics. The exception is S. squamosum, which overlaps with other species, and this results in significant levels of misidentification. Variation in the untranscribed H3-H4 histone intergenic spacer region of flies

1844. The cytotaxonomy and morphotaxonomy of Simulium mengense (Diptera: Simuliidae). (Abstract)

The cytotaxonomy and morphotaxonomy of Simulium mengense (Diptera: Simuliidae). Human onchocerciasis is hyper-endemic in south-western Cameroon and the island of Bioko. The vector on the island is the endemic 'Bioko' form of Simulium yahense. On the mainland, S. damnosum s.s., S. squamosum and S. mengense are recorded around Mount Cameroon but their contribution to transmission in the area is unclear. As elimination of onchocerciasis, through vector eradication, is a possibility on the island

1850. Cytotaxonomic description of Simulium kaffaense, a new member of the S. damnosum complex (Diptera: Simuliidae) from south-western Ethiopia. (Abstract)

Cytotaxonomic description of Simulium kaffaense, a new member of the S. damnosum complex (Diptera: Simuliidae) from south-western Ethiopia. Although Ethiopia is one of the countries worst affected by human onchocerciasis, the exact taxonomic identity of the blackflies acting as the main vectors in the endemic areas has never been determined. A cytotaxonomic analysis of Simulium damnosum s.l. collected from three endemic sites in south-western Ethiopia has now revealed the existence
