Soika, G., & Labanowski, G.S. 2003 Owady zasiedlajace pnie i pedy drzew i krzewów ozdobnych. [Insects occurring on shoots and trunks of ornamental trees and shrubs.]. Zeszyty Naukowe Instytutu Sadownictwa i Kwiaciarstwa w Skierniewicach 11: 89-97.

Notes: In Poland during 1995-2002, 14 insect species were found living on shoots and trunks of ornamental trees and shrubs in ornamental nurseries, botanical gardens and urban areas. They were divided into two groups, depending on the kind of damage and the place of feeding: insects boring holes inside trunks and those feeding on shoots and bark of trees. The first group was represented by Cryptorhynchus lapathi, Agrilus sinuatus and Synanthedon formiciformis. In the second group, 11 species of insects were identified: Aphrophora salicina, Gossyparia spuria, Pseudochermes fraxini, Pulvinaria sp., Lepidosaphes ulmi, Parthenolecanium corni, Eulecanium tiliae, Dreyfusia piceae, Pineus strobi, Pterocoma salicis and Plocamaphis brachysiphon.
