During the years 2016-2018, the natural enemies of Physokermes species, namely, Physokermes hemicryphus
(Dalman) and Ph. piceae (Schrank), were studied in Sebia. Populations of both species of the spruce bud scale
were found at a very high level. Five species of predators were reared from Ph. hemicryphus colonies: Anthribus
nebulosus Forster (Anthribidae), Exochomus quadripustulatus L., Scymnus abietis Paykull, Harmonia axyridis Pallas
(Coccinellidae) and Chrysoperla carnea (Chrysopidae). The same predator species were reared from Ph. piceae
colonies. The parasitoid species Aphycoides clavellatus (Dalm.), Microterys lunatus (Dalm.), Pseudorhopus testaceus
(Ratzeburg) (Encyrtidae), Coccophagus lycimnia Walker (Aphelinidae) and Aprostocetus sp. (Eulophidae) were
reared from both scale colonies while Eurytoma sp. (Eurytomidae), Metaphycus unicolor Hoffer (Encyrtidae) and
Pachyneuron muscarum L. (Pteromalidae) were reared only from Ph. hemicryphus colonies. Coccophagus piceae
Erdo...s (Aphelinidae) and Metaphycus stagnarum Hoffer (Encyrtidae) were identified as parasitoid associated only
with Ph. piceae. The most abudant predator species in both scale colonies, Ph. hemicryphus and Ph. piceae, was A.
nebulosus (45,72% and 57,11% respectively), while poliembrionic parasitoid, P. testaceus was the most abundant
parasitoid species (42,02% and 28,25% respectively). Shannon-Weaver diversity index and Equitability index were
used for analyzing the diversity of natural enemies on each locality. The calculated values of the Shannon-Weaver
were as follows, Ph. hemicryphus: 0,3-1,33 and Ph. piceae: 0,37-0,87. Equitability index varied from 0,02 to 0,58 for
Ph. hemicryphus natural enemies and from 0,097 to 0,21 Ph. piceae natural enemies, which indicate the unequal
distribution of natural enemy species.
