Abstract
Spruce bud scale, Physokermes piceae, develops on the genus Picea. Large colonies of this species are constantly present on Picea abies in green areas in the Belgrade territory, causing the drying of needles, branches and whole plants. Therefore, Ph. piceae is a significant spruce pest. Spruce scales attract many entomophagous insects able to reduce pest population. Parasitoid wasps Coccophagus lycimnia (Walk) (Aphelinidae) and Microterys lunatus (Dalm.) (Encyrtidae) were reared. Predators Exochomus quadripustulatus L., Scymnus abietis Paykull (Coccinellidae) and Anthribus nebulosus Forster (Anthribidae) were determined. Both species of ladybird were confirmed as predators of Ph. piceae for the first time in Serbia, while S. abietis is a new species for the fauna of Serbia. The most effective natural enemy of Ph. piceae was A. nebulosus, reducing populations by 68-80%.
