Velcheva, N. and A. Atanassov, 2016. Species diversity of parasitods reared from codling moth, Cydia pomonella (Linnaeus, 1758) andplum fruit moth, Grapholita funebrana (Treitschke, 1835) (Lepidoptera, Tortricidae) in Bulgaria. Bulg. J. Agric. Sci., 22: 272–277

Studies on species diversity and rate of parasitism of  larval and pupal parasitoids, of two major tree fruit pests, codling moth Cydia pomonella (Linnaeus, 1758) and plum fruit moth Grapholita funebrana (Treitschke 1835) were conducted in Bulgaria. Eighteen larval or pupal parasitoids were reared from codling moth and 7 larval or pupal parasitoids from plum fruit mothbelonging to 5 and 2 Hymenoptera or Diptera families, respectively. Two parasitoids of the codling moth and five parasitoids of the plum fruit moth are new host records for Bulgarian fauna.
Levels of parasitism ranged from 0.74% to 3.7%, and 0 to 4.9% of diapausing codling moth and fruit plum larvae, respectively. The highest percentages of parasitism were recorded for the first generation of plum fruit moth (5.7% - 7.6%) and in an event of very low fruitlessness of apple trees for codling moth (33. 3%). The guild of primary solitary larval endoparasitoids of both pests was the most numerous.
