Environmental determinants of the distribution of Culicoides (Diptera˸ Ceratopogonidae), vectors of animal viruses of economic interest, in Morocco
Culicoides are small blood-biting midges, belonging to the Ceratopogonidae family, the genus is present on all land surfaces except Antarctica. A very small proportion of the diversity of Culicoides has an epidemiological role with a significant impact on human and animal health. A few numbers of sp...

Culicoides are small blood-biting midges, belonging to the Ceratopogonidae family, the genus is present on all land surfaces except Antarctica.
