New Ichneumonidae (Hymenoptera) parasitoids of forest insect pests in Bulgaria
Anzeiger für Schädlingskunde, Pflanzenschutz, Umweltschutz 72 (3), 57-61
Abstract: During the period 1989-1998 investigations were carried out on the parasitoids of some forest insect pests in Bulgaria. Twenty-one Ichneumonid species are reported for the first time in Bulgaria as parasitoids of different coleopteran, lepidopteran, and hymenopteran hosts. From these, 6 parasitoids are new records for the parasitoid complexes of the hosts: Exochus decoratus Holmgr. on Eudemis profundana (Den. and Schiff.) and Gelechia turpella (Den. and Schiff.); Lissonota culiciformis Grav. - on Paranthrene tabaniformis (Rott.); Lissonota unicincta Holmgr. - on G. turpella; Xorides gracilicornis (Gray) - on Xylotrechus sp.; and Eriborus terebrator Aubert - on Clostera anastomosis (L.). Most parasitoids developed as primary parasitoids in the hosts. Itoplectis alternans (Gray) is a primary parasitoid of Nycteola asiatica (Krul.) and a hyperparasitoid of E. terebrator. Acropimpla pictipes (Gray) is secondary parasitoid on Anacampsis populella (Cl.). With the exception of two species of Olesicampe genus, which destroyed over 50% of Stauronematus compressicornis (E) and Pristophora conjugata (Dahlm.) larvae, and E. terebrator which killed 15.4 % of C. anastomosis population, the rest of the parasitoids occurred in low densities, and did not play an important role in reducing the number of their hosts.
