[5], More than 6,000 species and 783 genera are described worldwide, but since 1,100 are from well-studied North America, this is certainly an underestimate,[6] and a recent DNA barcoding study estimated the fauna of Canada alone to be in excess of 16,000 species, hinting at a staggering global count of over 1 million cecidomyiid species that have yet to be described, which would make it the most speciose single family in the entire animal kingdom.[7].

Abstract. A catalog of the Cecidomyiidae (Diptera) of the world Update for a catalog of the Cecidomyiidae (Diptera) of the world. The application of sex pheromones is an efficient method with which to monitor and manage gall midges. Cecidomyiidae show a great diversity of larval feeding habits, ranging from mycophagous, through highly specialized phytophagous (including gall makers), to zoophagous, with many species predaceous on insects and other invertebrates, or endoparasitic in aphids and psyllids (Harris 1994). Wings are covered with long hairs. As the larvae are incapable of moving considerable distances, a substantial population of prey must be present before the adults lay eggs, and the Cecidiomyiidae are most frequently seen during pest outbreaks. A major digestive proteinase in the guts of larvae of biotype D of Mayetiola destructor is a chymotrypsin-like serine proteinase which can hydrolyze [3 H]alpha-casein and benzoyl-l-tyrosine ethyl ester (BTEE).Hydrolysis of protein and ester by the gut proteinase were blocked by diisopropyl fluorophosphate (DFP) and inhibited by l-1-tosylamide-2-phenylethyl chloromethyl ketone (TPCK).
