Rauleder, H. 2011 Antagonisten und Prädatoren der Maulbeerschildlaus Pseudaulacaspis pentagona (Targioni – Tozzetti, 1886) (Homoptera: Diaspididae) in Baden-Württemberg. Erwerbs-Obstbau 53:51–58

Notes: Antagonists of the white scale (Pseudaulacaspis pentagona, T argioni-Tozzetti, 1886) were determined from peaches and sweet cherries as host plant at the orchards of the Centre for Agriculture and Technology Augustenberg (LT Z) in 2009 and 2010 as well as from four other commercial red and black currant orchards in Baden-Wuerttemberg in 2010. The study focused mainly on the parasitoid species of P. pentagona as well as the rate of parasitism of white scale caused by these parasitoids using emergence traps with invested branch samples of the different host plants in the laboratory. Beside the parasitoids, possible predators of the white scale were observed in the field in 2010 at the orchard of the LT Z. The two parasitic wasp species Aphytis diaspidis and Encarsia berlesei (Howard, 1881 and 1906) were determined as parasitoids of the white scale, whereas A. diaspidis was dominant at most sites. Rate of parasitism caused by both species ranged from 1.9 to 23.0%. The Kidney-Spot Ladybird Beetle (Chilocorus renipustulatus, Scriba, 1790) could be observed as a predator of the white scale in the field.
