First results of the application of isozyme analysis to study of Culicoides (Diptera: Ceratopogonidae).

Results of a biochemical study on the genus Culicoides are reported. A method of analysis using six discriminant enzymatic systems was used and the results obtained on zymograms are detailed. A genetic study of C. nubeculosus, based on phosphoglucomutase was carried out. The processing of the data obtained, by means of correspondence analysis, provides an interesting comparative study between morphologically related species.
