During studies on the taxonomy of the Simuliidae of Brazil, a new species of Simulium was found. Full descriptions of the adults and pupae of this species are described here, its affinities with other species are discussed and its distribution, biology, and medical importance in Brazil are recorded.

Onchocerciasis elimination is within reach in many countries but requires enhanced surveillance of the Simulium vectors Onchocerca volvulus. Collection sufficient numbers adult to detect infective O. volvulus larvae hindered by limited sampling tools for these flies. Here, we tested first time Host Decoy Trap (HDT), an exposure free method previously developed Anopheles malaria parasites, as a ...

Entomopathogenic bacteria isolated from Simulium larvae and adults from breeding sites in the states of São Paulo and Rio de Janeiro, Brazil, were identified as 18 strains of Bacillus thuringiensis and one of B. sphaericus. Most of these strains were serotyped according to their flagellar antigens. However, nine of the B. thuringiensis samples, could not be serotyped and were designated as "aut...

The purpose of this paper is to bring together all the available information concerning the control of Simulium vectors of onchocerciasis in Africa and Central and South America.Some of the larger control schemes are described in detail. Insecticidal formulations, rates of dosage, and methods of application are given when available, and costs per square mile (or square kilometre) are quoted whe...

Limnomermis subtropicalis n. sp. (Nematoda:Mermithidae) a parasite of Simulium orbitale Lutz (Diptera:Simuliidae) found in Argentina is described and illustrated. This species is characterized by having medium sized amphids, pocket-shaped, medium sized vagina, sculptured spicule, and by having 9 preanal, 7 postanal papillae in the ventral row, and 12 papillae in the lateral rows.

The family Simuliidae is the host of simbiontes fungi that inhabit the digestive tracts of arthropods. This paper reports the presence of fungi in Simulium goeldii Cerqueira & Nunes de Mello larvae in Amazonia. We observed that the larvae are a good component of aquatic systems to isolate filamentous fungi.
