Checklist of Scale Insects in Bulgaria (Hemiptera, Coccoidea)

The scale insects of Bulgaria are a comparatively well-studied group. The most substantial contribution was made by Tsalev (1968), who listed 89 species belonging to 8 families, 55 new to Bulgaria. Using all literary sources, we have increased the number of species found in Bulgaria to 145 in 11 families and 65 genera. Thirty-eight of these are of alien origin. The number of species now known in each family is as follows: Diaspididae 48 species in 21 genera, Pseudococcidae 33 species in 16 genera, Coccidae 33 species in 18 genera, Eriococcidae 13 species in 4 genera, Asterolecaniidae 6 species in 2 genera, Kermesidae 4 species in 1 genus, Ortheziidae 3 species in 3 genera, and Matsucoccidae 2 species in 1 genus. The Cerococcidae, Monophlebidae and Putoidae each have only 1 species in 1 genus. The previously unrecorded species listed here are taken from unreferenced text sources and so have not been included in ScaleNet. The paper provides information about outdoor and indoor species found in Bulgaria in last 75 years, since the first list of Coccoidea was published.
