  • A Quarantine Pest Research Facility (QPRF) had been build in Animal and Plant Quarantine Agency and designed to ensure alien pests are safety contained inside the laboratory. Functions of QPRF including insect rearing, research, and physical containment facility were verified to check suitability as a research laboratory using the beet armyworm, Spodoptera exigua. As insect rearing and laboratory facility, S. exigua completed its development for 32.2 days at 25℃. Egg hatching, pupation, and adult eclosion showed 80, 86.6, and 90%. Two pesticides, fluxametamide and hydramethylnon showed high susceptibility against S. exigua larvae by spraying and dipping methods. As physical containment facility, male adults, which were artificially released from laboratory, did not capture in delta trap installed sex pheromone lure during winter season. Based on these results, QPRF will be used for study on alien insect species.

  • In recent decades, the world has entered a new era in terms of the number and variety of biological invasions, due to economic progress and transportation efficiency. Biological invasion is becoming more likely as demand for foreign fresh foods and decorative goods grows. Alien species continue to infiltrate Korea in a variety of ways, and disturb on the insect fauna of Korea. The goal of plant quarantine is to decrease the economic impact of alien pests on the agriculture and forestry industries. In this study, we focused on insects found in imported cut flowers from 1996 to 2020 using pest information system. Overall, 147,160 cut flowers (159 items) were imported into Korea from 69 countries during this time period. Throughout this time, 467 species of insects were found in all imported cut flowers to Korea, total 13,757 detections. They were classified as provisional regulated pests in 273 species, quarantine managed pests in 78 species, and non-quarantine pests in 118 species. Thysanoptera and Hemiptera had the largest number of alien insect detections (more than 80% of the alien insects) among the nine orders. The outcomes of this study have highlighted the need for ongoing inspection activities targeted at preventing quarantine alien pests from entering or incursion in Korea.

  • Tetranychus urticae Koch and Panonychus ulmi Koch were identified as quarantine pests in apple samples and were controlled soon after the commercial treatment of methyl bromide (MeBr) and with irradiation doses $(0.5{\sim}3kGy)$ after irradiation. The physical qualities of apples, such as rotting, withering, weight changes, hardness, and color, were apparently affected by MeBr. Furthermore, more than 2 kGy irradiation resulted from the lapse of storage time. Associated with the physical qualities of stored apples, irradiation and fumigation for quarantine purposes were more adequate after 40 days of storage at $0{\pm}1^{\circ}C\;(85{\pm}2%\;RH)$ immediately following harvest, rather than soon after harvest. Less than 1 kGy irradiation, based on its accumulated control effect on pests, can potentially be applied as a quarantine procedure without causing significant changes in the physical qualities of fresh apples, in contrast to MeBr.

First Report in Korea of the Stored Grain Pest Cynaeus angustus (LeConte) and a Pictorial Identification Key for Tenebrionid Pests in Stored Products (새로운 저장곡물해충 Cynaeus angustus (LeConte) 및 저장산물의 거저리과 해충에 대한 도해검색)

  • The larger black flour beetle, Cynaeus angustus (LeConte) (Diaperinae: Tenebrionidae) is reported for the first time in Korea. C. angustus is economically important as an insect pest in stored products in the Nearctic region, and has been identified in several rice mills in Korea. Taxonomic diagnosis and photographs presenting the morphology of adults and larvae are provided, along with a pictorial identification key to 17 tenebrionid pests detected during quarantine in stored products in Korea.
