Matsucoccus matsumurae is the main forest insect pest of the Pinus thunbergii and Pinus densiflora in South Korea. In this experiment, we had verified the insecticidal effects of Amitraz, deltamethrin and sulfoxaflor, using ground spraying since the trunk injection has not been greatly effective for the control recently. We divided the methods for three ways to confirm the insecticidal effects by developmental stages. Firstly, in male, only amitraz among the insecticides showed significant mortality. Secondly, in female, none of the treatments showed significant mortality but showed delay synthesize the wax filaments when the amitraz treated. In addition, sulfoxaflor treatment showed significant lower egg production rate. Lastly, in 2nd nymph, all insecticides were not shown insecticidal effect. Above the results shown that the ground spraying of three insecticides for M. matsumurae was not a proper control method.

Monochamus alternatus which is major vector for Bursaphelenchus xylophilus is main pest for pine trees. Moreover, their larvae mainly feed on the phloem of the host during the growth period, and this process makes host debilitate. The reason why the epidemiological investigation of that damage caused by Monochamus alternatus is difficult is that the adult and the larva remains very rarely in the host. Even if the larvae remain in the host, it is not easy to distinguish them from other cerambycidae coleopterans without expertise. For the above reason, we introduce the method of field epidemiological investigation for Monochamus alternatus using the remaining larva frass in the host with Recombinase Polymerase Amplification (RPA) method.

여행객 휴대 수입금지식물에서 발생하는 금지해충(과실파리류, 코드린 나방 등)의 유입 가능성이 높아짐에 따라 지속적인 모니터링을 통하여 품목별, 국가별로 검출되는 해충의 정보 축적이 필요하며, 검역해충 종 동정을 위하여 표본 확보 및 분류학적 정보가 필요하다. 2018년 1월부터 12월까지 인천공항 및 인천항으로 반입되어 압수한 휴대식물 중 사과, 배, 복숭아에서 검출되는 해충을 조사하였다. 그 결과 형태학적 동정 및 DNA 바코딩 분석을 통하여 Carposina sasakii (복숭아심식나방), Grapholta molesta (복숭아순나방), Grapholita dimorpha (복숭아순나방붙이) 등이 검출되었지만 우려하는 코드린나방은 검출되지 않았다. 본 연구결과는 휴대 반입식물에서 검출되는 해충 종 구성에 대한 검역자료로 활용될 수 있을 것으로 판단된다.

Spotted wing drosophila (SWD), Drosophila suzukii (Diptera: Drosophilidae), is an important quarantine insect pest on blueberry and strawberry exportation in Korea. Due to IPPC recommendations of replacement of methyl bromide (MB) and recent critical issue about its chronic inhalation toxicity to fumigator and related workers along with post-fumigation, alternatives to MB is urgently required. Thus, we evaluated efficacies of ethyl formate (EF) to SWD eggs using two different bioassay methods; using eggs oviposited on artificial diet and on blueberries naturally infested with SWD adults. In results, there was no differences between two bioassay methods in terms of LCT99 value of EF.

Honey bees are affected by a variety of factors, so they have to be thoroughly managed according to their lifestyle. The activity of the honey bee foragers represent an important parameter of the hive state. Here, the real-time and automatic monitoring system using dual infrared sensors was applied for counting the foraging activity of honey bees based on ICT. According to this study, this system is very accurate with a relative error of 3.98% / 4.43% compared to manual counting through video analysis. This system showed the scalability of the system through the internal and external temperature sensors connected through the main board and BLE module. Furthermore, the data measured through this system for one month were analyzed, the monthly average foraging activity and the number of lost foragers were measured (1.88% of outgoing bees), and at the same time, the foraging patterns according to the changes of temperature and time were analyzed. This study suggests that the development of apicultural, scientific and educational materials with more powerful real-time monitoring tools through expansion of a complex monitoring system and big data accumulation.

Cotesia Cameron is a cosmopolitan genus of the subfamily Microgastrinae. This genus comprises more than hundreds of species (Whitfield et al., 2009). The members of the genus Cotesia parasites on larvae of Macrolepidoptera: Noctuidae, Geometridae and Saturniidae (Achterberg & Polaszek, 1996; Whitfield et al., 2009). Previously, 33 Korean species of the genus have been investigated by several researchers (Kim, 1963; 1970; Ku et al., 2001; Papp, 1974; 1990; 2003). In this study, Cotesia urabae is reported for the first time from Korea. Diagnosis, distribution, and host information are provided.

The insecticidal activity of Bacillus thuringiensis subsp. israelensis (Bti) is due to synergistic interactions among its four major proteins (Cry4Aa, Cry4Ba, Cry11Aa, Cyt1Aa), while the activity of Lysinibacillus sphaericus (Ls) is due to a binary toxin (Bin) consisting of a toxin domain, BinA, and a midgut receptor-binding domain, BinB. Although used commercially for almost three decades, reports of mosquito resistance to Bti have been rare. However, levels of resistance greater than 10,000-fold to Bin have been reported where Ls has been used intensively for mosquito control. Cyt1Aa is a lipophilic protein, and in previous studies we showed it delays the evolution of resistance to the Cry proteins of Bti, and can overcome high levels of resistance Bin. In a previous study, we fused Cyt1Aa to BinA, using the lipophile as a broad-spectrum binding domain and showed that the Cyt1Aa-BinA chimera was remarkably toxic to five major vector species of mosquitoes, Anopheles gambiae, An. stephensi, An. quadrimaculatus, Bin-sensitive and Bin-resistant strains of Culex quinquifasciatus, and Aedes aegypti, the latter not normally sensitive to Ls. However, toxicity against Aedes aegypti was not as high as against other mosquito species. Here we show that introducing another highly mosquitocidal protein, Cry11B from B. thuringiensis subsp. jegathesan, enhances the chimera’s toxicity against Ae. aegypti significantly but not against Cx. quinquefasciatus.

An investigation on the habitation of Callipogon relictus Semenov was carried out in Gwangneung forest, Korea and Ussurisky nature reserve, Russia. During the investigation period (2007–2018), a total of 25 emergence holes, 10 pupal chambers, 10 adults, and two larvae of C. relictus were identified in Gwangneung forest. In this presentation, we provide biological information on habitation of C. relictus in Gwangneung forest by comparison and combination of survey results in Ussurisky nature reserve, in 2015 and 2018. In addition, the distribution range of C. relictus is also reviewed in the Korean Peninsula with a new location.

Small hive beetle (Aethina tumida Murray, 1867) (SHB) is one of the important pests of bee keeping industry. This species is endemic in sub-Saharan region of Africa that has recently became an invasive and distributing rapidly throughout the world. Recent detections of SHB in Philippines, Brazil and South Korea indicate that SHB has the potential to become a global pest for apiculture and wild bees. Having enough knowledge about the population source of invasion can help understand the pest ecology and develop the control tactics. SHB has invaded to South Korea in 2017 and cause heavy damage to apiaries in Miryang City, in south-eastern part of Korea and the origin of this pest is still unknown. The aim of this study is to evaluate the phylogenetic position and origin of Korean population of SHB. We sampled the SHB from different bee hives in Miryang city and used 922 bp part of cytochrome oxidase subunit 1 (CO1) region of mitochondrial DNA to compare with all previously reported COI sequences of SHB. The result showed that the population of SHB in south Korea is classified with South Africa, Zimbabwe, Madagascar, Canada, Australia and USA populations in one clade and among them, the lowest genetic distance between South Korean and USA populations indicated that most likely the SHB was imported from the United states to South Korea. No genetic difference has been detected between studied sequences from Korean population indicating that the invasion would had happen in one occasion.

Drosophila suzukii Matsumura (Diptera: Drosophilidae) is known as a pest that has a wide host range. This study was carried out to investigate the occurrence of D. suzukii by trapping D. suzukii in Korean strawberry greenhouse and its surrounding woodland from November, 2017 to April, 2019. As a result of trap monitoring, the greatest capture was recorded in fall and secondary peak was confirmed in summer in a lower capture. It was confirmed that there was a statistically significant difference between the occurrence among inside and outside of the greenhouse and the woodland. The strawberry greenhouse cultivation area of Korea is mainly located in the plain region, whereas most of the other host plants for D. suzukii are usually grown at the ridge of the mountain or hillside. Therefore, if considering the living environment of host plant, monitoring result that showed more capture in woodland than strawberry greenhouse would be explained.

Comparative toxicity of different groups of pesticides on Apis mellifera L. were tested in the laboratory. Commercial formulations dissolved in water from the highest dose level marked on the label were serially diluted to 10^(-6) times to carry out oral trials on each pesticide. Fungicide (Metconazole), herbicide (Glyphosate), acaricide (Amitraz) and 3 insecticides (organophosphate Fenitrothion, neonicotinoids of Thiacloprid and Thiamethoxam) were compared. Thiamethoxam and fenitrothion caused higher mortality, and amitraz showed intermediate level of mortality while herbicide and fungicide showed minimal impacts. Among neonicotinoids, Thiamethoxam was highly toxic but thiacloprid showed mortality less than 25% even at the highest concentration. LC50 values were estimated as Amitraz 197.70, Fenitrothion 2.20, and Thiamethoxam 0.188 ppm at 24 h after treatment. Fungicide, herbicide and a neonicotinoid thiacloprid were all showed low oral toxicity. This study confirmed that the old pesticide, organophosphate was highly toxic and two different toxic path way exist for neonicotinoid pesticides.

A residual contact vial plus water (RCVpW) bioassay method was established to monitor insectiside resistance in field populations of the melon thrips, Thrips palmi. Resistance level against six major insecticides were evalutated in five regions to test applicability of RCVpW as an on-site resistance monitoring tool. Reduced mortality in response to six test insecticides were exhibited compared to the RDA susceptable strain showing 100 % mortality, indicating different degree of resistance. An apparently reduced mortality to emamectin benzoate and chlofenapyr was observed in some field populations, suggesting uneven distribution of resistance to these insecticides in field populations. In addition, spinosad resistance was high and widely distributed in the test regions. Synergistic bioassay revealed that cytochrome P450-mediated metabolic factor is involved in spinosad resistance in the Korean population.

식식성 파리류는 농업경제학적으로 매우 중요한 분류군으로 인식되어 분류, 예찰 및 방제, 생태, 생리 등 다양한 분야에서 활발한 연구가 진행되고 있다. 식식성 파리류의 습성은 leaf-miners, stem-borers, root tunnellers, fruit borers, cambium miners, seed borers, inhabitants of flowerheads 등이 대표적으로 알려져 있으며, 식물체의 다양한 부위를 공격한다. 대부분의 식식성 파리류는 한 종의 식물을 공격하는 것으로 알려져 있으나, 일부는 2종 이상의 식물체와 관련이 있다. 이들은 생태학적 습성으로 인해 비교적 크기가 작고 변이의 폭이 넓어, 분류동정이 어려운 특징이 있다. 따라서, 최근 통합분류학적 접근을 통한 계통학적 연구, 예찰 및 방제를 위한 유인물질의 개발, 잡초 방제를 위한 생태학적 연구 등이 활발히 이루어지고 있다. 본 연구를 통하여 분류군별 생물학적 특징과 세계적인 연구동향을 정리하여 소개하며, 추가적으로 연구가 필요한 분야에 대해 제안하고자 한다.

Insect neuropeptides are involved in most physiological processes in insects, such as diuresis, ecdysis, and pheromone biosynthesis. The peptides perform these functions as ligands for G-protein coupled receptors (GPCRs) that trigger specific biochemical functions. Our research in this area has focused on the Pheromone Biosynthesis Activating Neuropeptide (PBAN) and its GPCR in fire ants. I will show that PBAN is involved in fire ant pheromone production and interestingly, also in important functions of all colony life stages. Since many neuropeptides play critical roles in insect development and reproduction, the peptide hormones and their receptors are viewed as promising targets for novel biologically-based control. These possibilities will be illustrated. Secondly, the use of venom alkaloids, cuticular hydrocarbons, and pheromones as useful taxonomic characters will be illustrated using Solenopsis species in the USA and in South America.

On December 27, 2017, the 31st session of the Standing Committee of the 12th National People’s Congress passed the Vessel Tonnage Tax Law of the People’s Republic of China. China’s Vessel Tonnage Tax Law has basically maintained the stability of the vessel tonnage tax collection system and accorded with the basic national conditions of China’s shipping industry. The system established by China’s Vessel Tonnage Tax Law is basically a traditional vessel tonnage tax system, which is different from those implemented by many other countries. This paper explores the reason why China chooses to implement the vessel tonnage tax system and evaluates the policy within a certain scope and from a certain angle. It also examines the shortcomings of China’s vessel tonnage tax system as well as the burden brought by it to the shipping enterprises and puts forward countermeasures and suggestions for reforming and perfecting the vessel tonnage tax system in China.

With the coming of the information era, Chinese administrative rule of law is experiencing an profound reform not only in the field of administrative basic theory, but in the field of administrative practice, not only in the field of administrative execution, but in the field of administrative legislation, not only in the field of real world but in the field of virtual world. Confronting such a reform, scholars of Chinese administrative law should scheme ahead to reflect upon the present theory of administrative law from all-round aspects, timely adjust related theory so as to the construction of administrative rule of law. This article mainly analyses the conflicts, dilemma of Chinese administrative rule of law, points out some outlets of Chinese administrative rule of law under the conditions of the information age.

Despite the current developments in creation of state security, the question of affording energy security is of paramount importance worldwide. Hence, all countries try to adopt myriads of laws and regulations aimed at energy security. Energy security relates to the degree of economic welfare attached to the rise or fall in either the price or availability of energy. The Islamic Republic of Iran, on the one hand is located in a strategic center of producing and exporting energy (oil and gas) known as “ellipse of energy.” On the other hand, it is situated in the transit way of energy to large consuming markets such as South and East of Asia and Europe. Thus, Iran is currently considered as an effective player in providing energy security in the world. In this article, the authors seek to analyze the strategic policies and priorities stipulated in the oil and gas-related regulations of Iran in terms of energy security.

We want to have an opportunity to learn in a global context why GAN is so important to Jeju as Korea's largest Island in a multi-cultural society. Politically, Jeju Island succeeds have to survive ordeal from Jeju 4.3 Grand Tragedy. Geologically, as Jeju Island is located at center of East Asia, it has benefits from easy access to main cities to the island such as Beijing, Shanghai, Tokyo, Osaka, Seoul, Busan, Hong Kong, Taipei and so on. Environmentally, as Jeju was designated UNESCO Biosphere, World Natural Heritage and Geo parks, we want to keep it as a longevity island. Culturally, as we recognize it as a specialized in Western countries by human peace, Jeju as a World Peace Island tries to integrate aging human life agenda into part of a human life one. As the result, we suggest “Korea Care into Global Humanity in the Asia Pacific Context” as integrated policy agenda of both Korea and Peace Island villages for the 2021 GAN Biennial Conference from September 26 to 30, 2021 in Jeju Island Korea. As it based on village healing by villagers, Jeju island is small, as there is slrong soldarity between, we believe it can revive Korea communities.
