  • Forensic entomology is a study that purposes at field reconstruction through insects attracted to carcasses, and has been mainly studied using carcasses such as a pig and chicken. Therefore, this study was conducted to find out if there is a singularity by using the carcass of water deer with different conditions and shapes of the hair quality and to find out the appearance of a necrophagous insect. The water deer carcass was received from the Jeollanam-do Wildlife Rescue Management Center and research was conducted. From May 19 2021 to July 2 2021, the decay progress of the carcass was observed for about 6 weeks. A total of 51 species of 21 families in 4 orders of insects were collected. Even after the carcass completely decays, even at the stage where the activity of other insects is not observed, insects such as Dermestidae and Tenebrionidae are collected from the hairs and leather of water deer carcass until the last. It was confirmed that insects of the order Coleoptera other than Diptera can be used as forensic entomological data related to the decay of carcasses with fur.

  • The insect industry in Korea has been supported by the Act of Fostering and Supporting Insect Industry since 2010. Based on the Act, insect breeders are entitled as farmers. However, the insect industry is not included in the Fundamental Act of Agriculture, Rural Community and Food Industry which defines all concepts, such as agriculture, farmers, and agricultural products. Legally and strictly speaking, there is no method to defense the insect industry when an argument is raised that insect industry is not included into agriculture, so persons who breed insects are not eligible for all agricultural supports and subsidies of the government. Thus, it is necessary to clear the legal status of insect industry by revising the related laws and regulations.

  • These researches were carried out to investigate the morphology of different species of Trichoderma and the possibilities of differentiation of the species of Trichoderma by electrophoretic methods. Variations between the isolates of a species of Trichoderma indicate the genetical differences, also isozyme and protein patterns will be useful to investigate genetical variations betweens the isolates. It might be possible that distinct bands of isozymes of esterase, phosphotase, catalase, catalase differentiate species of Trichoderma.

  • Simple mass-rearing methods for Spodoptera exigua Hubner with an artificial diet were done in th laboratory. Hatchability of egg and its survival rates upto 3rd instar lava were 97.9 and 83.3 ercent, respectively. The pupation rates in individual rearing, mass-rearing, mass-rearing with sawdust were 48.5%, 37.5%, and 82.5%, respectively. The emergence rates in those methods were 85.2%, 86.7%, 90.9%, respectively.

  • Sweet potato whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is an insect pest with sucking mouth part and globally attacks diverse crops and vegetables. Since first reported in 1998, it is now widely spread in many regions in Korea. Due to insecticide resistance, it is necessary for optimal control of the whiteflies to select effective insecticides with precise insecticide resistance monitoring. In this study, B. tabaci individuals were collected from 12 regions in 7 provinces of Korea from June to September in 2020. Using these field populations, insecticide resistance levels were monitored using a residual contact bioassay along with molecular markers. Bioassay results revealed that B. tabaci possessed high levels of resistance to five insecticides exhibiting different modes of action: dinotefuran, spinosad, emamectin benzoate, chlorfenapyr, and bifenthrin. In addition, quantitative sequencing in target sites of organophosphate and pyrethroid insecticides revealed that point mutations reached to saturated or near-saturated levels across the country. This suggests that insecticide resistance management is required for effective control of B. tabaci populations in Korea.

  • The influnces of 9 kinds of solvents on the toxicities against several insect species, phytotoxicity and solubility of compounds were evaluated by means of leaf dipping and spray methods. In case of the spray application, density and vapor pressure seemed to be a contributing factor to lethal toxicity against brown planthopper and diamond-back moth, respectively; the bigger the property of density and the smaller the vapor pressure gave the stronger toxicity. It appeared that the toxicity of solvents was not correlated with anyone of physical properties such as boiling point, dipole moment, dielectric constant, surface tension and viscosity. Spray treatment gave more toxicity to insects than leaf dipping treatment. Although dielectric constant and dipole moment seemed to be contributing factors to phytotoxic damage to rice seedling and bean plants, respectively, no general correlation between phytoxicity and the other physical properties was found. Leaf dipping application caused stronger phytotoxicity than spray application. It is concluded that 5% acetone solution may be most suitable to test chemicals because of its favorable solubility of compounds, lower toxicity to insects, and lower phytotoxicity.

  • To develop a microbial pesticide for the control of pine gall midges. Thecodiplosis japonensis, entomopathogenc fungi were isolated from 233 soil samples in the damaged region of Thecodiplosis japonenesis, and identified with Beauveria spp. 29 strains and Paecilomyces spp. 2 strains. The morphology of entomopathogenic fungi was observed by scanning electron miroscope. In addition, the toxicity of entomopathogenic fungi was observed by scanning electron microscope. In addition, the toxicity of entomopathogenic fungi isolated from soil samples was determined by bioassay against Thecodiplosis japonensis larvae. The result showed that toxicity of relatively pathogenic strains, Beauveria spp. SFB-168-2 was 82.9%, suggesting that Beauveria spp. SFB-168-2 is effective entomopathogenic fungi for the control of pine gall midges.
