HISTORY:
In 1758 Linnaeus first assigned 17 species of "Coccus"(the nominal genus of the Coccoidea) in his Systema Naturae with three of his species are still recognized as Diaspids (aonidum,ulmi, and salicis). In 1828 (circa) Costa proposed three subdivisions including Diaspis.Bouche in 1833described the Genus Aspidiotusf . Targioni-Tozzetti from 1868 to 1870 described more species. Takahashi and Takagi. Ferris and McKenzie described in detail the common genera Aonidiella, Chrysomphalus, and Parlatoria. Ben-Dov (Israel), Ray Gill (CDFA, retired), Dug Miller (Systematic Entomology Lab, ARS) and Gillian Watson (ARS, CDFA).
Several catalogues were also developed since 1877:
- In 1877 The Signoret Catalogue was the first compilation of the first century of post-Linnaeus systematics of scale insects. It listed 9 genera consisting of 73 species of the diaspididae.
- In 1903 the Fernaldi Catalogue listed 35 genera with 420 species.
- In 1966 Borschenius Catalogue listed 335 genera with 1890 species.1983: 390 genera with 2200 species.9.2004:
Hemiptera, Sternorryncha alone comprised of 32,000 known species. Of these, 2390 species are Diaspididae and 1982 species of Pseudococcidae reported on Scalenet at the Systematic Entomology Lab.
