Once a month, from June 1992 to May 1993, collections of tabanids on horse were conducted in the Nhecolândia, Pantanal State of Mato Grosso do Sul, Brazil. Tabanid catches using hand nets were conducted from sunrise to sunset at grassland and cerradão (dense savanna) habitats. A total of 3,442 tabanids from 21 species,12 genera, and 3 subfamilies were collected. Although species abundance varie...

BACKGROUND Horsefly sting causes allergic reactions in human body. However, our knowledge on horsefly allergens remains poor. OBJECTIVES To identify the novel horsefly allergens and characterize their properties. METHODS A native allergen protein Tab y 1 (apyrase) was purified from the salivary glands of the horsefly Tabanus yao Macquart by gel filtration and ion exchange chromatography. It...

Abstract Background Tabanids are a neglected group of haematophagous dipterans despite containing 4434 species, regrouped in > 144 genera. They mechanical vectors important pathogens, including viruses, bacteria and protozoa humans domesticated wild animals. As it is 50 years since the publication preliminary nationwide record tabanids Cameroon identified 84 updated information needed. The a...

The horse ßy Tabanus nigrovittatusMacquart (Diptera: Tabanidae), a hematophagous insect, is a nuisance pest along the Atlantic Coast. A description of the engorgement pattern throughout the season is lacking in the literature for this species. Thepercentageof ßies engorging abloodmeal in the laboratory throughout the season was recorded, and here we demonstrate that the percentage of ßies that ...

Tabanid females are better known as hematophagous on man and other mammals, and linked to mechanical transmission of parasites. The association between tabanids and reptiles is poorly known, but has been gaining more corroboration through experiments and occasional observation in the tropics. The present study was conducted at a military base (CIGS/BI-2), situated 54 km from Manaus, Amazonas, i...

The Egyptian Government plan to move in 25 years from an inhabited area of 6-25% of the total Nile land area to a larger one to compensate the huge increase of Egyptian populations. The decision was recently made to begin a development project at Toshka, on the western bank of the River Nile, Upper Egypt. Toshka depression is more or less close to Wadi Halfa of Sudan. Therefore, it was necessar...

BACKGROUND Tsetse flies are obligate blood-feeding insects that transmit African trypanosomes responsible for human sleeping sickness and nagana in livestock. The tsetse salivary proteome contains a highly immunogenic family of the endonuclease-like Tsal proteins. In this study, a recombinant version of Tsal1 (rTsal1) was evaluated in an indirect ELISA to quantify the contact with total Glossin...
