Drosophila melanogaster is a species of fly (the taxonomic order diptera) in the family drosophilidaethe species is known generally as the common fruit fly (though inaccurately) or vinegar flystarting with charles w woodworth's proposal of the use of this species as a model organism, d melanogaster continues to be widely used for biological research in genetics, physiology, microbial. For species other than drosophila melanogaster, the valid gene symbol follows a species abbreviation indicating the species of origin the prefix has the form nnnn\ , where n is the initial letter of the genus ( ie , d for drosophila or dettopsomyia) and nnn is a unique code, usually the first three letters of the species name (eg, sim for.
