We report new host records of four ichneumonids from Korea. They were discovered from the pupae of Apatura metis Frever (Lepidoptera: Nymphalidae), Allotraeus sphaerioninus Bates (Coleoptera: Cerambycidae) and Ivela auripes (Butler) (Lepidoptera: Lymantriidae) respectively. Diagnoses, illustrations, host records of the four species, and a list of ichneumon species parasitizing of I. auripes are provided.

Life history of Ivela auripes (Lepidoptera: Lymantriidae), a pest of Cornus controversa, was investigated both in laboratory and field condition. At $24{\pm}1^{\circ}C$, developmental period from larvae to adult and adult life span was $26.3{\pm}0.3$ and $4.4{\pm}0.2$ days, respectively. Developmental period of pupae reared in the laboratory was not significantly different from those collected in the field. Female moths reared in the laboratory laid significantly less eggs than those emerged from the pupae collected in the field. Light trap catches was less effective than direct monitoring in the field. The two monitoring results showed that adult moth emerged from early June to late June, and the time of 50% cumulative emergence was 17 June.

Ichneumonidae are well-known parasitoids that attack the larvae or pupae of other insects. This study analyzed whether the abdominal DNA of two ichneumonid wasps, Pimpla disparis and Theronia atalantae gestator, showed the signature of the host species, Ivela auripes. Observations confirmed that these two ichneumonids were the representative parasitoid species growing in the larvae of I. auripes. In addition, sequence analysis showed that the mitochondrial cytochrome oxidase I gene of the host was amplified completely from the DNA extracted from the gut tissues of the ichneumonids. Even after 96 h of adulthood, the host's DNA traces did not disappear and were amplified in many individuals. These results suggest a constructive first step for establishing of a host information bank for ichneumonids in the future.
