Six Ichneumonini species, Barichneumon constrictus (Uchida, 1956), Ctenichneumon albomaculatus (Uchida, 1956), Diphyus salicatorius (Gravenhorst, 1820), Ichneumon ohtaniensis Uchida, 1926, Ichneumon kuroishiensis (Uchida, 1929) and Stenichneumon odaiensis Uchida, 1932, are reported for the first time in Korea. Photographs and redescriptions are provided.

Kim and Son (1969) reported an ichneumon-fly, Megarhyssa jezoensis Matsumura, as a parasite of Sirex nitobei Matsumura which is one walnut, Juglans sinensis Maximowicz but Sirex nitobei Matsumura was misdetected by them. The host of Megarhyssa jezoensis Matsumura is not Sirex nitobei Matsumura but Tremex apicalis Matsumura which was unrecorded in Korea up to the date. And the fact is added that Ibalia takachihoi Yasumatsu also attacks the same pest, Tremex apicalis Matsumura.

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.

Rearing of tropical tasar silkworm, Antheraea mylitta Drury is mainly conducted in outdoor on Terminalia tomentosa W. & A. a nature grown primary host plant available in forest and also on raised primary host plant Terminalia arjuna Bedd. Temperature, relative humidity and rainfall are the main environmental factors for occurrence of pests (parasites and predators) of tasar silkworm during I, II and III crop rearing in the tropical tasar producing zones. The present study was aimed to study the influence of abiotic factors on prevalence of tasar silkworm pests. The study was conducted at different agro-climatic regions viz., Central Tasar Research &Training Institute, Ranchi, Jharkhand, Regional Extension Centre, Katghora, Chattisgarh and Regional Extension Centre, Hatgamaria during 2010-13 covering 3 seed crop and 6 commercial crops. Data on incidence of tropical tasar silkworm endo-parasitoids like Uzi Fly, Blepharipa zebina Walker and Ichneumon fly (Yellow Fly), Xathopimpla pedator, Fabricius and Predators such as Stink bug (Eocanthecona furcellata Wolf), Reduviid bug (Sycanus collaris Fabricius) and Wasp (Vespa orientalis Linnaeus) was recorded Weekly. The meteorological data was collected daily. Data was collected from 4 different agro-climatic zones of tasar growing areas. Analysis of the data revealed a significant negative correlation between abiotic factors and incidence of ichneumon fly and uzi fly. Based on the 3 years data on prevalence of pests region-wise pest calendars and prediction models were developed.

This paper reports new hosts for three ichneumonids (Apophua evanescens evanescens, Teleutaea minamikawai, and Trathala flavoorbitalis) from South Korea. These three species were discovered from the lepidopteran pupae, viz., Cleora leucophaea (Butler) (Geometridae), Adoxophyes honmai Yasuda (Tortricidae), and Pyrausta phoenicealis (Hübner) (Crambidae), respectively. Among these, the lepidopteran family Geometridae and Crambidae are also newly recorded as host groups for the genera Apophua and Trathala.

An ichneumon-fly, Megarhyssa jezoensis Matsumura, was found as a parasite of Sirex nitobei Matsumura, a pest insect of the walnut, Juglans sinensis Maximowicz, at Ye-San, Choong-Nam province, middle Korea. The life cycle of Megarhyssa jezoensis was as follows: 1. It occurred three times a year. The adults appear at the end of April to the middle of May (maximum on 5th May) after hibernation, at the beginning to the middle of July (maximum on 10 th July) in the first generatioin, and at the end of September to the end of October (maximum on 8 th October) in the second. 2. The larvae grew from the beginning of May to the end of June in the first generation, from the middle of July to the beginning of September in the second and from the beginning of October to the end of the year in the last. 3. The pupae developed from the end of June to the middle of July and from the end of August to the middle of September. 4. The adults oviposited their eggs on the surface of the host, the larvae in Sirex nitobei growing in the stem of the walnut, and the larvae hatched from the eggs were ectoparasiting the larvae of Sirex to grow and pupate. The parasite hibernated in the pupal stage but the adult which emerged at the early spring stayed in the hole of the walnut stem till the end of April.
