The section of habitat used by particular bloodsucking insects when seeking bloodmeals may influence the spectrum of hosts to which they have access and consequently the diseases they transmit. The vertical distribution of ornithophilic bloodsucking Diptera (Culicidae, Simuliidae and Ceratopogonidae) was studied using bird-baited traps set at both ground and tree canopy levels. In total, 1240 m...

All stages of Simulium (Meilloniellum) adersi (Pomeroy) from Mayotte, Comoro archipelago are described in detail. This species is widespread on the African mainland and in Madagascar; morphological divergences from African material point towards the Mayotte entity being a separate, but closely related species. Biology of the species overall is reviewed and brief comments are made regarding habi...

Bacillus spp. based larvicides are increasingly replacing, with numerous advantages, chemical insecticides in programmes for controlling black fly and mosquito populations. Brazil was among the pioneers in adopting Bacillus thuringiensis israelensis (B.t.i) to control black flies. However, the major current mosquito control programme in Brazil, the Programme for Eradication of Aedes aegypti lau...

The history of the study of bloodsucking mosquitoes, sand flies, black flies, and horse flies in St. Petersburg and Leningrad Province is observed. At present, 38 mosquito species of 5 genera, 67 black fly species of 17 genera, 24 species of bloodsucking sand flies of the genus Culicoides, and 36 horse fly species of 6 genera were revealed in the territory of the region. The analysis of 267 col...

Simulium (Nevermannia) berchtesgadense nov. spec. is described from the Alps of southeastern Germany. The morphology and diagnostic characters for all life stages except the egg are given, and the polytene chromosomes are compared with those of other members of the Simulium (Nevermannia) vernum group. The species is chromosomally similar to Simulium (Nevermannia) cryophilum cytoform 'A' but dif...

A new black fly species, Simulium (Nevermannia) subratai sp. nov., is described on the basis of female, pupal and larval specimens collected from Darjeeling, India. This new species is assigned to the feuerborni species-group of the subgenus Simulium (Nevermannia), and is characterized by the entirely yellow female thorax and the larval abdomen without any colored markings. This is the first re...

We synonymize Hellichiella pugach Perkovsky & sukhomlin, 2015 with Gre­ niera yankovskyi Perkovsky & sukhomlin, 2015 (stegopterniini) based on the holotype and female paratype of H. pugach (stegopterniini). Hellichiella po­ lessica n. sp. differs from Hellichiella oligocenica (rubtsov, 1936) (the only species of Hellichiella known in Baltic amber) by its smaller body, narrower head, 11-segmente...

On the basis of sex chromosome variation, three cytotypes of Simulium squamosum (Enderlein) (Diptera: Simuliidae) are described from Cameroon and Nigeria. Simulium squamosum A is the typical form as originally described by Vajime & Dunbar (1975) with chromosome I as the sex chromosome. It occurs throughout most of Cameroon and south-east Nigeria. A second cytotype, S. squamosum B, is described ...
