  • Hymenoptera stings can cause serious injury to humans. We report the clinical findings of 6 cases of Hymenoptera stings. All patients developed painful erythematous papules at the sting sites and had a past history of parasitoid wasp sting. This is the first clinical report of the parasitoid wasp, Cephalonomia gallicola, causing human stings in Korea.

  • When the parasitic wasp Microplitis croceipes experiences odors while feeding on sugar water, it learns to associate the odors with sugar and thereafter exhibits typical food searching behavior in response to the odors. Previous studies have shown that this wasp can be used for detection of the small amount of explosives or other volatile chemicals. In the present study, we examined if this wasp can learn and report narcotic odors. Males of M. croceipes were trained to link sugar water with pseudo-narcotic scents that have been used for training narcotic detection dogs, and their behavioral response to the trained odors was observed. The males that had been given either an odor or sugar water did not show any positive response to the odors. However, when the wasps were given a combination of sugar water and either the pseudo-Cocaine, Heroin, LSD or Marihuana, they quickly learned to associate the odors with sugar, and thereafter positively responded to those odors. Our results suggest that this wasp can be used for detection of these narcotics.

  • The species composition of the parasitoid complex and the degree of parasitism by each species were analyzed for gypsy moth (Lymantria dispar) populations in the increasing phase. Total of 7,826 mid-late instar larvae and pupae were collected and reared from two collection sites in Gangwon Province, Korea. Two tachinid flies (Blepharipa schineri and Parasetigena silvestris), and the ichneumonid wasp (Coccygomimus disparis) were the most abundant parasitoids, in the order of decreasing importance. Other parasitoids occurring included Coteisa melanoscelus, Cotesia scheaferi, Glyptapanteles liparidis, Brachymeria lasus, and Exorista spp. The low incidence of the NPVirus is hypothesized to be an important factor in determining degree of parasitism rate by P. silvestris and B. schineri, and their relative dominance in the parasitoid complex.

  • The Samurai wasp, Trissolcus japonicus (Ashmead) (Hymenoptera: Platygasteridae) is recognized as a solitary parasitoid on eggs of the stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), an economic pest causing severe damage to fruits, in South Korea. The wasp appears to be a potential biological agent of the pest. In addition, T. itoi Ryu and T. nigripedius (Nakagawa) were found to parasitize eggs of Eurydema gebleri Kolenati and Dolycoris baccarum Linnaeus, respectively. Diagnostic characters and photographs are provided for identification, and host records of Korean Trissolcus species are also given.

  • A commercial egg parasitoid, Trichogramma sp. Nabis101, was released into agricultural cultivating areas in Korea due to its wide host spectrum against insect pests. Moreover, an application technique has been recently developed to enhance its control efficacy by mixture treatment with a microbial control agent. Despite its expansion of commercial availability, any genetic identification on this commercial strain was not determined. Also, to meet inconsistent demands from consumers, the live parasitoids need to be stored without significant loss of their survival and parasitic activity. This study determined nucleotide sequence of internal transcribed spacer (ITS) of the wasp species. The identified ITS sequences indicate that this wasp species is most similar to T brasiliensis. Optimal storage condition of this wasp required young parasitized stage at $10^{\circ}C$. Under these conditions, survival, sex ratio, longevity, and parasitic behavior were not much impaired for 5 weeks.

  • The genus Opius Wesmael, 1835 (Hymenoptera: Braconidae: Opiinae) generally parasitizes larvae of Agromyzidae, Anthomyiidae, Drosophilidae, Tephritidae, Ephydridae and Cecidomyiidae, of which 32 species are recorded in South Korea. In China, seven new species of the genus Opius have been known. Among them, Opius crenuliferus Li & van Achterberg, 2013 is reported for the first time in South Korea. Specimen was collected by sweeping in West Daeshin-dong, Busan, Korea. In this study, description, and diagnostic illustration of O. crenuliferus are provided.

Efficacy of an Integrated Biological Control of an Egg Parasitoid, Trichogramma evanescens Westwood, and Microbial Insecticide Against the Oriental Tobacco Budworm, Helicoverpa assulta (Guenée) Infesting Hot Pepper (고추를 가해하는 담배나방[Helicoverpa assulta (Guenée)]의 효과적 방제를 위한 쌀좀알벌(Trichogramma evanescens Westwood)과 미생물제제의 종합생물방제 효과)

  • Due to internal feeding behavior, the oriental tobacco budworm, Helicoverpa assulta ($Guen\acute{e}e$), infesting hot pepper has been regarded to be effectively controlled by targeting egg and neonate larval stages just before entering the fruits. This study aimed to develop an efficient biological control method focusing on these susceptible stages of H. assulta. An egg parasitoid wasp, Trichogramma evanescens Westwood, was confirmed to parasitize the eggs of H. assulta. A mixture of Gram-positive soil bacterium, Bacillus thuringiensis subsp. kurstaki, and Gram-negative entomopathogenic bacterium, Xenorhabdus nematophila ANU101, could effectively kill neonate larvae of H. assulta. A sex pheromone trap monitored the occurrence of field H. assulta adults. The microbial insecticide mixture was proved to give no detrimental effects on immature development and adult survival of the wasp by both feeding and contact toxicity tests. A combined treatment of egg parasitoid and microbial pesticide was applied to hot pepper fields infested by H. assulta. The mixture treatment of both biological control agents significantly decreased the fruit damage, which was comparable to the chemical insecticide treatment, though either single biological control agent did not show any significant control efficacy. This study also provides morphological and genetic characters of T. evanescens.
