Non-destructive testing (NDT) technology is a widely used inspection method for agricultural products. Compared with the conventional inspection method, there is no extensive sample preparation for NDT technology, and the sample is not damaged. In particular, NDT technology is used to inspect the internal structure of agricultural products infested by pests. The introduction and spread of pests during the import and export process can cause significant damage to the agricultural environment. Until now, pest detection in agricultural products and quarantine processes have been challenging because they used external inspection methods. However, NDT technology is advantageous in these inspection situations. In this pilot study, we investigated the feasibility of X-ray computed tomography (X-ray CT) and magnetic resonance imaging (MRI) to identify pest infestation in agricultural products. Three kinds of artificially pest-infested fruits (mango, tangerine, and chestnut) were non-destructively inspected using X-ray CT and MRI. X-ray CT was able to identify all pest infestations in fruits, while MRI could not detect the pest-infested chestnut. In addition, X-ray CT was superior to the quarantine process than MRI based on the contrast-to-noise ratio (CNR), image acquisition time, and cost. Therefore, X-ray CT is more appropriate for the pest quarantine process of fruits than MRI.

Tropical fire ant, Solenopsis geminata (Fabricius) is distributed over the tropical and temperate areas. It is a polyphagous pest attacking to various plant and causes the pain to the people doing outdoor work. So it is known for a hygienic pest to human being, especially the people doing outdoor activities. It can cause severe pain to human, even with just a bite. Of particular concern is the possibility of its settlement in this country, if it invade to the farmlands and/or forests of Jeju Island and southern part in Korea. It is listed as a regulated pest in Plant Quarantine Act of Korea. This ant is usually imported through a ship and early settled in the port area where it is already distributed. Recently its distribution is rapidly spreading into Southeast Asia and southern part of China. In Korea, it was detected the one time in 1990s, but was detected the ten times from 2000 to 2006 by an imported plant quarantine process. Therefore, we would like to provide some information on the species, including morphology, distribution, host plant, damaged symptom and its general bionomics, which will be useful data for plant quarantine process and control.

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.

The blossom midge, Contarinia maculipennis Felt (Diptera: Cecidomyiidae) originated in Southeast Asia and is present in Japan, the continental USA, and Hawaii. Recently, C. maculipennis was intercepted in Japan, USA and the Netherlands by using orchid flowers imported from Southeast Asian countries. This pest is designated as a quarantine pest in Korea because of its potential damages to vegetables and ornamental plants. In Korea, similar symptoms of damage, which mighty be caused by C. maculipennis, have been investigated in western orchids, especially on Dendrobium phalaenopsis, from Mid-2000s. Official recognition was given to C. maculipennis in 2007, followed by an investigation on the occurrences of C. maculipennis and its damages, mainly on D. phalaenopsis, in 2008~2009. We emphasize caution concerning the possibilities that C. maculipennis could infest flower buds of orchids and carry out management strategies for this pest in the future.

As a series of studies to develop pest management system for sweet persimmon production matched with the quarantine criterion of sweet persimmon-imported county, a survey was conducted by questionnaire on pest management practice and scheme of increasing income in sweet persimmon farms in Korea. Above 80% of sweet persimmon farmers was over fifties in age. The greatest limiting factor for sweet persimmon production was thought to be disease by the farmers. Percentage of farmers who answered that the most important pest is anthracnose cause by Gloeosporium kaki, and stink bugs was 64.6% and 73.5%, respectively. In particular, the farmers did not consider Dichocrocis punctiferalis, a main targer insect for quarantine in USA, as serious problem. Obtaining information on pest management practice or decision-making on both selection of pesticide and time of pesticide application depended highly on their own experience with the highest proportion. Eight to nine times of pesticide applications a year was highest among farms with 56.6%. More than 80% of farmers recorded the diary of pesticide application. farmers considered increasing cost for pest management as the greatest problem with 35.4% in proportion, and 34.5% of farmers pointed out that increase in export is essential for increasing farm income with highest proportion.

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.

In October 2009, hunting billbug, Sphenophorus venatus vestitus Chittenden, was first found on zoysiagrass at Yongweon country club in Jinhae. The adult was 6~11mm long and dark brown to black color. The pronotum is coarsely punctate except for a "Y"-shaped area in the center and a parenthesis-like marking on each side. This pattern is characteristic of the species. This billbug feeds on warm-season grasses like zoysiagrass and Burmudagrass. As the hunting billbug is one of the plant quarantine pests in Korea, the National Plant Quarantine Service surveyed additional occurrence for neighboring golf courses and some turfgrass farms, but not found yet.

On-site survey on glue-laminated board (GLB) manufacturers of Malaysia, Indonesia, and China was conducted to identify the cause of interception of regulated pest from imported GLBs from those countries, and to suggest optimal manufacturing processes of GLB for preventing quarantine risk associated with imported GLBs. The cause of pest interception was improper manufacturing processes, such as air drying or inadequate kiln drying of green laminae, improper storage of dried laminae before finger jointing and edge gluing, and/or incomplete packing of GLBs. In particular, Paulownia GLB manufacturing processes used in China, including air drying of laminae, were mostly poor in terms of preventing quarantine risk associated with imported GLBs. From now on, for preventing quarantine risk associated with imported GLBs, importers have to ask foreign manufacturers spontaneously to use proper manufacturing processes (adequate kiln drying of green laminae, proper storage of dried laminae, and complete packaging of final GLBs).
