The complex of parasitoids of the feeding larvae of Cydia pomonella L. (Lep.: Tortricidae)
Mitteilungen der Schweizerischen Entomologischen Gesellschaft 73 (1-2), 13-22
Abstract: By rearing of active caterpillars (in the feeding process) of Cydia pomonella L., collected in 1996 from two ecosystems around the city of Iasi (Romania), 5 hymenopteran species were obtained as primary parasitoids: Pristomerus vulnerator PANZ., Liotryphon crassisetus THOMS., L. punctulatus RATZB. (Ichneumonidae), Ascogaster quadridentata WESM. and Microdus rufipes NEES (Braconidae). 2 species were recorded as secondary parasitoids: Perilampus tristis MAYR (Perilampidae) and Baryscapus talitzkii (KOST.) (Eulophidae). P. vulnerator is the most important component of this parasitic complex, both by its presence and by the high values of the parasitism ratio (9.2-28.1 % recorded in Iasi-Sorogari and 3.3-5.5 % in the lasi-city). P. tristis was obtained from P. vulnerator, A. quadridentata and M. rufipes, with A. quadridentata as the preferred host, the highest parasitism ratio, recorded in Iasi-Sorogari, being of 66.7 %.
