Abstract


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.

    Members of the family Ichneumonidae usually attack the larvae and pupae of holometabolous insects or adult spiders (Quicke, 2015;Takasuka et al., 2018). Generally, many ichneumon wasps are parasitoids of lepidopteran larvae or pupae. This study reports new hosts for the three ichneumon species (Apophua evanescens evanescens, Teleutaea minamikawai, and Trathala flavoorbitalis) in South Korea. Among these, the genus Apophua and Teleutaea belong to the subfamily Banchinae.

    The genus Apophua is a moderately large group encompassing 38 species worldwide. Of these, seven species are found in South Korea. This genus is an endoparasitoid of the lepidopteran larva, especially the leaf-roller Caterpillar (Tortricidae) (Kamijo, 1973;Momoi et al., 1975). These species are also known to attack other lepidopteran larvae (Noctuidae and Zygaenidae) and coleopteran larvae (Attelabidae, Cerambycidae, and Curculionidae) (Yu et al., 2016). One South Korean species, Apophua evanescens evanescens, is easily distinguished from other species by the following characteristics: without areolet, simple convex clypeus, 2nd to 4th tergites with oblique grooves, and 2nd tergite longer than its apical width. This species is a known parasitoid of Nolidae, Tortricidae, and Zygaenidae. Nine species have been reported as hosts for this species, with only two species recorded in South Korea. In this study, this species was additionally recovered from Cleora leucophaea (Butler) (Lepidoptera: Geometridae).

    Teleutaea is a moderately sized genus comprising 20 described species from the Palaearctic, Neotropic, and Oriental regions (Yu et al., 2016). Eight species have been recorded in South Korea. These species are known entoparasitoids of the leaf-roller Caterpillar (especially Tortricidae). One South Korean species, Teleutaea minamikawai, is easily distinguished from other species in having a large yellow spot on the mesopleuron, a thick yellow mark on the pronotum, and a simple antennal socket (not prolonged). Five species have been reported as hosts for this species, with four species recorded from South Korea. In this study, this species was also discovered in Adoxophyes honmai (Lepidoptera: Tortricidae).

    The genus Trathala belonging to Cremastinae, is a large cosmopolitan group comprising 102 species (Yu et al., 2016). Among them, only two species have been recorded from South Korea. Most of these species are known endoparasitoids of the superfamily Pyraloidea (Lepidoptera). The characteristics of one South Korean species, T. flavoorbitalis, easily distinguish it from other species: visible sternite, complete occipital carina, and entirely yellow body color. In all, 80 species have been reported as hosts to this species, with 22 species recorded in South Korea. This species has now been recovered from Pyrausta phoenicealis (Hübner) (Lepidoptera: Crambidae).

    This paper provides the diagnosis, plate, and host record of three parasitoids, Apophua evanescens evanescens, Teleutaea minamikawai, and Trathala flavoorbitalis.

    Materials and Method

    The materials used in the present study were collected by rearing and were deposited at the Daegu National University of Education (DNUE, Daegu, South Korea). Distributional data and host records were categorized according to Yu et al. (2016). A host list recorded from Korean fauna is hereby provided. All Korean species are as per the National Species List of KOREA (2019).

    The abbreviations used in the present study are as follows: DEI, Deutsches Entomologisches Institut, Eberswalde, Germany; SEHU, Laboratory of Systematic Entomology, The Hokkaido University Museum, Hokkaido University, Sapporo, Japan; NHM, The Natural History Museum, Department of Entomology, London, England; USNM, United States National Museum of Natural History, Smithsonian Institute, Washington D.C., U.S.A.; TD, Type depository; TL, Type locality.

    The South Korean provinces examined were: CB: Chungcheongbuk- do; JJ: Jeju-do.

    All specimens were examined using an AxioCam MRc5 camera attached to a stereomicroscope (Zeiss SteREO Discovery V20; Carl Zeiss, Göttingen, Germany), processed using Axio- Vision SE64 software (Carl Zeiss), and optimized with a Delta imaging system (i-solution, IMT i-Solution Inc. Vancouver, Canada). The morphological terminology followed that of the American Entomological Institute website (http://www.amentinst. org/GIN/morphology.php).

    Collecting data of new host. JJ, Seogwipo-si, Hwasun Gotjawal, 29.vi.2020, SS Kim (host plant: Sapindus mukorossi Gaertn.).

    Remark. The new host of Apophua evanescens e., Cleora leucophaea was collected in Sapindus mukorossi Gaertn. Adult Apophua evanescens e. was discovered in the pupa of C. leucophaea approximately after a month (22.v.2020). The family Geometridae was also newly recorded as a host group. C. leucophaea is therefore termed polyphagous.

    Remark. The new host of Teleutaea minamikawai, Adoxophyes honmai was collected in Oehmeria tricuspis (Hance) Makino and Piper kadsura (Choisy) Ohwi. Adult of T. minamikawai was discovered in the pupa of A. honmai approximately 10-20 days later (09.iv.2020 and 11.iv.2020 each). Tortricidae, belonging to Adoxophyes honmai, is a pest that damages fruit trees by feeding on leaves or preventing further growth by rolling them. Especially, A. honmai is known to attack young leaves and reduce the yield of green tea.
