The genus Bitomus Szepligeti, 1910 (Hymenoptera: Braconidae: Opiinae) is known to parasitize in mining flies (Diptera: Agromyzidae), of which four species are recorded in Korea. Bitomus was revised by Fischer (1987, 1994) and recently treated by Papp (1978, 1981) in Korea. Bitomus is distinguished from other genera by the immovably joined second-third or fourth metasomal tergites, forming a carapace. In this study, Bitomus indicus is recognized for the first time in Korea. This study provides a diagnosis, description, distribution, and diagnostic illustrations.

Spathius ibarakius Belokobylskij et Maeto, which belongs to the Spathius exarator species group (Hymenoptera: Braconidae: Doryctinae) was found as an ectoparasitoid of the first- and second-instar larvae of the citrus longhorned beetle, Anoplophora chinensis ($F{\ddot{o}}rster$) from Gwangneung, Pocheon, Korea. The discovery of this braconid wasp was made during the survey for parasitoids of the Asian and citrus longhorned beetles by using the sentinel log method. We herein describe diagnostic characters of S. ibarakius, including those of the male, and also provide illustrations. In addition, we present a host list of Korean species belong to genus Spathius.

The natural enemy was identified as a parasitic wasp, Binodoxys communis Gahan. B. communis taxonomically belongs to the family braconidae, subfamily aphidinae, and genera binodoxys. It develops normally at 17.5 to 32.5℃, and not at 35℃. Depending on the temperature, the longest development period of B. communis was 21.9 days at 17.5℃, and shortest was 6.46 days at 32.5℃. The effective accumulated temperature was 175.44 DD for females as well as males; however, the developmental threshold temperature was 10.87℃ and 10.74℃ for females and males, respectively. This parasitic wasp was found to prefer cotton aphids and soybean aphids as its prey.

The genus Areotetes van Achterberg & Li, 2013 (Hymenoptera: Braconidae: Opiinae), which is endoparasitoid of mining or infesting of fruit dipterous larvae, have been reported for the first time in China. Currently, four species of the genus Areotetes have been known from the province Hunan and Fujian, China. In this study the genus Areotetes with Areotetes carinuliferus van Achterberg & Li, 2013 is reported for the first time from Korea. Material studied in the present study were collected by sweeping in Mt Gongchi, Eochungdo, Province Jeonbuk, Korea. Herein, diagnosis of genus, description, distribution, and diagnostic illustration of A. carinuliferus are provided. In addition, DNA barcode data of the partial gene of mitochondrial cytochorome c oxidase subunit I (COI) are included.

Polydnaviruses are a group of double-stranded DNA viruses and are symbiotically associated with some ichneumonoid wasps. As proviruses, the replication of polydnaviruses occurs in the female reproductive organ at the pupal stage. This study analyzed the effects of two developmental hormones, juvenile hormone (JH) and ecdysteroid, on the viral replication of Cotesia plutellae bracovirus (CpBV). All 23 CpBV segments identified contained a conserved excision/rejoining site ('AGCTTT') from their proviral segments. Using quantitative real-time PCR based on this excision/rejoining site marker, initiation of CpBV replication was determined to have occurred on day 4 on the pupal stage. Pyriproxyfen, a JH agonist, significantly inhibited adult emergence of C. plutellae, whereas RH5992, an ecdysteroid agonist, had no inhibitory effect. Although RH5992 had no effect dose on adult development, it significantly accelerated viral replication. The results of immunoblotting assays against viral coat proteins support the effects of the hormone agonists on viral replication.

The genus Ephedrus Haliday, 1833 is a large taxon of Aphidiinae, consisting of 48 valid species in the world. This genus is considered to be important as a biological control agency, which includes solitary koinobiont parasitoids on aphids. One of its interesting characteristics is both male and female have 11-segmented antennae. In previous study, this genus was subdivided into three subgenus, Breviephedrus, Ephedrus and Fovephedrus, based on molecular and morphological characters. In this study, one Ephedrus species is firstly recorded from South Korea. Since it has been collected from Geumsan-gun in 2005 and deposited as dried specimen at Naturalis Biodiversity Center in Netherland, we recently confirmed it. Description and illustrations of the E. lacertosus are provided.
