  • Diadegma fenestrale is known as a parasitoid of the potato tuber moth, Phthorimaea operculella. The potato tuber moth, Phthorimaea operculella (Zeller) is one of the most destructive pest of potatoes. Also, we found this species attacking the diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae). Ratio of parasitism is 20-30% and cocoon of lepidopteran was parasitic ichneumonid species after 3 days. This species and the genus Diadegma are recorded for the first time from Korea. In this paper, description of the parasitoid and photographs of the diagnostic characteristics are provided.

  • The subfamily Campopleginae $F{\ddot{o}rster$ is the third largest group of Ichneumonidae, comprising more than 2,130 species worldwide. At present 55 species within 13 genera have been reported from South Korea so far. Five species, Campoplex tosensis (Uchida, 1932), Diadegma majale (Gravenhorst, 1829), Dusona myrtilla (Desvignes, 1856), Hyposoter didymator (Thunberg, 1822), and Scirtetes robustus (Woldstedt, 1877), of the subfamily Campopleginae (Hymenoptera: Ichneumonidae) are recognized for the first time from South Korea. In addition, the genus Scirtetes is reported for the first time from South Korea. Diagnostic illustrations and diagnoses of the five newly recorded species are provided.

  • Forty six individuals out of 200 Acronicta rumicis larva were parasitized (23 %) in 2000, 14 individuals out of 60 (23.33 %) in 2001, and 14 individuals out of 62 (22.58 %) in 2002. The mean parasitism rate was $22.97{\pm}0.38%$. The parasitism rate was 36.36 % in May and 52.78 % in October, 2000, 75 % and 50% in May and October 2001, 71.4% and 47.37% in May and October 2002 and it was much higher than other months. Parasitism was occurred from May to October 2000, but it was not in June and August 2001 and June 2002. There was no difference in the monthly mean parasitism rate, but the rate was the highest in May and October. The parasitoid of the larva of A. rumicis was the highest by 77.02% of parasitic wasps, and 13.51% of parasitic flies. It was found that multiparasitism was 4.05 % and hyperparasitism was 5.41 %. In case of parasitic wasps whose parasitism rate is the highest, the rate of Braconidae and Ichneumonidae was 70.18 % and 29.82 % respectively. That is, the former has much higher parasitism rate. The parasitism rate of the larva of A. rumicis was found that Microplitis sp. is $5.28{\pm}0.63%$, Glyptapanteles liparidis $8.62{\pm}3.70%$, and Diadegma sp. $4.02{\pm}1.28%$ respectively.
