AbstractOverwintered pupae of fall webworm, Hyphantria cunea(Drury), were collected from 38 hazelnut (Corylus avellanaL. (Betulaceae)) plantations in Samsun province, Turkey, in 2008 and 2009. Four chalcidoid (Hymenoptera: Chalcidoidea) species were reared: Chouioia cuneaYang (Eulophidae), Conomorium amplum(Walker), Dibrachys boarmiae(Walker), and Psychophagus omnivorus(Walker) (Pteromalidae). Overall parasitism was 11.97% and 4.84% for 2008 and 2009, respectively; species richness on sites ranged from one to three species. Psychophagus omnivorusparasitised 6.7% of all pupae and comprised 79% of chalcidoid rearings. Chouioia cuneahad the highest clutch average (117) and female:male ratio (44.5:1). Records of Chouioia cuneaand Conomorium amplumare new for Turkey and, except for P. omnivorus, all parasitoids are new records for H. cuneain Turkey. |
