Tremex apicalis Matsumura as a Host of an Ichneumon-fly, Megarhyssa jezoensis Matsumura

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.
