Diversity of biting midges of the genus Culicoides Latreille (Diptera: Ceratopogonidae) in the area of the Yacyretá Dam Lake between Argentina and Paraguay.
TLDR
The Culicoides communities have been analyzed between 1993/1998 in the area influenced by the Yacyret Dam Lake (Paran River, Argentina-Paraguay) and the taxonomic structure of communities was constant during the study period, with highest values of species richness and species diversity recorded during 1993/1994.

TLDR
This revision of the Dasyhelea cincta group of biting midges in Patagonia recognizes two previously described species and a new species, Dasy helea filiductus Diaz & Spinelli, from Argentinean Patagonic, which is recorded for the first time from Argentina.

Preparation and Mounting of Biting Midges of the Genus Culicoides Latreille (Diptera: Ceratopogonidae) to be Observed with a Scanning Electron Microscope
TLDR
Techniques tending to the preservation of the original morphology and the mounting of species of Culicoides for SEM, especially larvae and adults, are discussed, with Nembutal was the most efficient of the relaxing drugs used.
A new method using acid to clean and a technique for preparation of eggs of biting midges (Diptera: Ceratopogonidae) for Scanning Electron Microscope
TLDR
In the new procedure eggs in different states, with different ultra structures of the exochorion, were immersed in 10% glycolic acid and 20 % mandellic acid, and retained their natural form under vacuum long enough to yield good microphotographs of the outer layer of the chorion.
