Ultrastructure of the eggs of Culicoides circumscriptus, Culicoides gejgelensis, and Culicoides imicola (Diptera:Ceratopogonidae).
The eggs of Culicoides circumscriptus Kieffer, Culicoides gejgelensis Dzhafarov, and Culicoides imicola Kieffer collected in Israel are described and illustrated by scanning electron micrographs. Eggs of all 3 species were morphologically similar, generally sausage- or cigar-shaped, with slight dorsal-ventral curvature and longitudinal rows of tubercle pillars covered with a thin adhesive layer. Tubercle pillars were scarce on C. circumscriptus and C. imicola eggs, but were common on C. gejgelensis eggs, forming longitudinal plastrons with an associated hydrofuge meshwork. All 3 species had micropyle domes and associated aeropyles at the anterior end of their eggs.
