The genus Rosalia contains three subgenera of which distinctly divided by different body colors and distributional patterns. Eurybatodes is a monotypic subgenus with yellow tegument only found in Yunnan, China. Eurybatus is the most specious subgenus contains 21 species with reddish body color, widely distributed in Oriental region including Taiwan and Ryukyu islands. The blue subgenus Rosalia contains 5 species that distributes West Palaearctic, East Palaeartic, Japan, Oriental and West Nearctic, respectively. Here we present the ongoing research on multi-gene phylogeny and evolutionary studies of the genus Rosalia. This study provides new insight into the internal relationships and the evolutionary history of various traits (e.g. biogeography, colors, elytral patterns) of the genus Rosalia.

The plant bug family Miridae is the largest group in Heteroptera, and is one of the most important insect groups economically in agriculture and in forestry, because it contains insect pests and predators. Among the subfamilies, Deraeocorinae represents the predatory group including some members which can be used as a biological control agent. This group comprises a total of six tribes in whole regions with their own unique morphology. However, the monophylies and relationships of tribes and genera within this subfamily are not still explored phylogenetically. In this talk, the first phylogenetic analyses of Deraeocorinae are presented based on total evidence data. Major questions including monophylies and relationships of each taxa on the basis of the results are discussed.

Grapholita molesta (Busck) is a major pest of stone fruits. Immature fruits of apricot and plum are well known food source during early summer for G. molesta, but those immature fruits have rarely been evaluated. Thus, we assessed biological and behavioral attributes of G. molesta when provided with immature fruits of apricot and plum in laboratory. The initial response rate (when larva reached to the center from release point in Y-tube olfactometer) of first instar was not different between apricot (70.0%) and plum (60.0%) of which sugar content was more on plum (5.92 brix in apricot and 7.30 brix in plum). However, pupal weight was less in apricot (7.5 mg) than in plum (11.4 mg), and this might be affected by difference in hardness of the fruits (17.2 N on apricot and 13.3 N on plum). The preoviposition period was also longer in apricot (6.3 d) than plum (3.6 d), and fecundity was lower on apricot (64.5) than on plum (135.0). Therefore immature plum fruit would be better food source for G. molesta than apricot during early summer.

Coccidae is one of the major families of scale insects, with many species considered to be serious agricultural or horticultural pests. However, the phylogenetic relationships among coccid subfamilies, tribes and genera are poorly understood because the previous hypotheses are based only on morphological characters and cladistic analysis. Here, we present the first molecular phylogeny of the family based on DNA fragments of a mitochondrial gene (COI), nuclear ribosomal RNA genes (18S and 28S), and elongation factor-1α (EF-1α). We recover a monophyletic family Coccidae with strong support. However, some genera (Coccus and Pulvinaria), tribes (Coccini, Paralecaniini, Pulvinariini and Saissetiini) and subfamilies (Coccinae and Filippiinae) within the family found to be paraphyletic- or polyphyletic. Moreover, particular types of wax formation, which have been used as important taxonomic characters in Coccidae, were found in several unrelated taxa.

From 2017 to 2018, the occurrence of leafhopper species in eight landscape trees (Acer palmatum, Elaeagnus umbellata, Lagerstroemia indica, Pinus densiflora, Prunus serrulata, Pseudocydonia sinensis, Rosa hybrid, Zelkova serrata) in Sangju, Gyeongbuk Province was investigated using flat traps from the leaf open season to the fallen season. E. rosae was the most abundant, and the highest density was observed in cherry trees. E. rosae outbreaks occurred at the end of March, early August, and early October, and are estimated to occur three generations a year. High attraction was observed in yellow plate traps than in blue. From the middle of October, the number of E. rosae increases only in Pinus densiflora among 8 species of trees, and it is estimated that pine trees are wintering places.

We investigated developmental characteristic of life cycle of the lawn cutworm, Spodoptera depravata (Lepidoptera: Noctuidae), which is one of the most economically damaging pests to grasses. For larval culture the turfgrass, Zoysia japonica (Poales: Poaceae), was provided at 25℃ and 60 ± 5% humidity. Developmental period of each stage was as follows: 4.11 ± 0.19 days for eggs, 25.17 ± 3.02 for larvae, 8.80 ± 0.28 for pupae and 7.57 ± 0.95 for adults. Larvae was grown to 7th instar, unlike pre-existing data, which indicated the final age as the 6th instar. Body length of larvae changed on average from 2.772 mm immediately after hatching to 2.3 cm at 7th instar and head capsule width changed on average from 0.423 mm at 1st instar to 2.82 mm at 7th instar. Pre-period of eggs deposition was 2 days, oviposition period was 4.6 days, average fecundity per female was about 419 eggs, and hatching rate was about 83%.

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.

The black pine bast scale are the main insects of the Japanese black pine forest in Korea, and the distribution is spreading around the Japanese black pine forest in the east and west coast. However, after the nationwide survey in 2010, there has been no investigation on the distribution and spread of these, so we conducted the 2017 and 2018 surveys to determine the extent of the northern area inland or east and west. In the 2017 survey, outbreaks were observed in 35 areas from 47 dong or myeon of 14 cities or counties, mainly in areas not previously located in the outbreak area. In the 2018 survey, additional outbreaks were confirmed at 14 out of 23 areas in the East Coast region, and damage was detected at 27 out of 28 points in the inland area of the South Sea and distribution was found at 16 out of 17 in the west coast.

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.

Learning and memory are essential for animals like honey bee, in which foragers leave their nest to collect food and then successfully learn to navigate back to colony. Chronic environmental exposure of neoniconitiod highly affect pollinators like honey bee. We investigated the effect of neonicotinoid, thiacloprid and imidacloprid on learning, memory and mortality of pollen foragers based on their toxicity level. Individual Pollen foragers Apis mellifera were trained using a proboscis extension proboscis. We used three treatments: 50% sugar solution, 50% sugar contaminated thiacloprid and imidacloprid as unconditioned stimulus and 2M 1-nonanol as conditioned stimulus. Our result shows that there is no significant difference between control and thiacloprid treatment both in learning and mortality of honey bee. But we found difference in memory between subjects exposed to control and thiacloprid contamination. Whereas imidacloprid contamination significantly lowered learning, eradicate memory retention and higher mortality of honey bee. Even thiacloprid and imidacloprid are in the same chemical class of Neonicotinoid insecticides, their toxic level would be different resulting in differential ecological impact to honey bee colony.

Naturally occurring plant toxins, such as benzoates, have been shown to have insecticidal effects on some pest insects. In this study three commercially available benzoates, methyl benzoate (MB), ethyl benzoate (EB), and vinyl benzoate (VB), were assessed for their contact toxicity against Aphis gossypii Glover and its lacewing predator Chrysoperla carnea Stephens. Toxicity of 1% MB, EB, and VB showed 100%, 85% and 60% mortality of A. gossypii at 24 h. In addition, a mixture of MB and EB showed higher synergistic effect than mixtures of MB+VB or EB+VB against A. gossypii. Toxicity at 1% concentration of three benzoates against A. gossypii showed lower toxicity against the larvae of C. carnea after 72 h of exposure than A. gossypii. Our result suggest that benzoates have high potential as environmentally safe biopesticides for A. gossypii control.

Red mite, Dermanyssus gallinae is one of the serious pests, damaging to the egg production in chickens. Moreover, the overuse of chemical insecticides caused pest resistance and environmental residual toxicity. Therefore, this work provides a screening method to select entomopathogenic fungi as a candidate of environmentally safe control agent, having high miticidal activity against D. Gallinae. The virulence test was conducted using a spraying method. Of the several species, Beauveria species showed high virulence and mycosis were observed. Some isolates were produced on eight cereal grains in Petri dish conditions. Millet, perilla seed and barley showed the high conidia production. Conidia of the isolates produced on millet and rice showed high thermal stability, when exposed to 45℃. Based on these results, this work suggests that entomopathogenic fungi could be used to control the D. Gallinae.

Mosquitoes are primary medical insect pests due to their diseases transmission as vectors. In Korea, the insecticide-resistant populations of disease vector mosquito species, such as Anopheles sinensis, Culex pipiens and Culex tritaeniorhynchus, have constantly increased. Thus, management of insecticide resistance to major insecticides including pyrethroids and organophosphates is required for more efficient control of resistant populations. In this study, the quantitative sequencing (QS) protocols were established to detect the frequencies of three mutations (the L1014F on voltage sensitive sodium channel and the G119S and F331W on acetylcholinesterase 1) that are associated with either pyrethroids or organophosphates. Based on the QS protocol using newly designed non-polymorphic primers, resistance allele frequencies (RAFs) were estimated in field populations of An. sinensis, Cx. pipiens and Cx tritaeniorhynchus collected from an identical site in Korea. The dynamics of each resistance allele frequency over time in the same populations were also evaluated.

Silverleaf whitefly, Bemisia tabaci is a worldwide agricultural pest that cause serious damage to crops. However, since this insect developed resistance to variety of chemicals, alternative control strategy needs to be studied. In this study, we aimed to evaluate the potential of entomopathogenic fungi as biological control tools against this pest. We developed a dipping method in laboratory conditions to screen insecticidal activity of different fungal species and isolates against the nymphal stage of whitefly. The highly virulent isolates were characterized and 2 isolates were further selected based on their high conidial productivity and thermotolerance. Finally, several grain substrates were used to confirm the conidial productivity and thermotolerance of the selected isolates, revealing optimum conidial production when the fungi were cultured on millet grains. Both isolates could be used in further millet grain-based formulations to control the whitefly in fields.

솔껍질깍지벌레는 남부지방의 곰솔을 가해하는 주요 해충으로 최근 그 분포범위가 확산되고 있다. 현재 솔껍질깍지 벌레의 모니터링은 난낭의 조사를 통해 이뤄지고 있으나, 이는 매우 많은 인력이 필요하며 부정확하다. 따라서 페로몬을 이용한 솔껍질깍지벌레의 모니터링이 새로운 대안으로 제시되고 있다. 하지만 이 역시 적절한 가이드라인이 없어 현장적용에 큰 어려움이 있다. 본 연구 에서는 페로몬을 이용한 솔껍질깍지벌레의 효율적인 모니터링 기법 개발을 위하여 최적 페로몬 방출농도 및 트랩설치 방법을 규명하였으며, 페로몬의 새로운 합성기법의 개발 통하여 경제적 효율성을 기하였다. 성 페로몬에 대한 수컷 솔껍질깍지벌레의 유인효과는 100 μg부터 1,600 μg 까지의 처리에서 용량의존적인 관계를 나타내었으며 이 이상으로 처리할 경우 페로몬 처리 증가에 따른 유인개체수가 증가하지 않았다. 트랩의 설치 높이를 지표면으로부터 50cm, 100cm 150 cm로 구분하여 조사한 결과 지상부로부터 50cm에 설치한 트랩에 가장 많은 개체가 포획되었다. 새로운 방법으로 합성한 페로몬 역시 기존 페로몬과 마찬가지로 페로몬 처리량과 유인 개체수 간 용량의존적인 관계가 나타났다.

Spodoptera litura Fabricius is the serious, polyphagous pest of various crops. Due to the high resistant to most of chemical pesticides, it is hard to control S. litura in the fields. We investigated the virulence of four entomopathogenic nematodes (EPNs) in each larval stage. All EPNs were more effective to younger larvae than older larvae. Mortality, larval penetration rate and reproduction rate were significantly higher in H. indica, S. carpocapsae and S. longicaudum than the H. bacteriophora. Three high effective EPNs induced complete mortality of first instar larvae within 48 h, but of fifth instar larvae within 72 h. These EPNs also highly effective to control S. litura in pot assay. Thus, H. indica, S. carpocapsae and S. longicaudum, can be used as efficient biological control agents of S. litura.

Age-stage two sex life table was constructed for a predatory lacewing, Chrysoperla carnea feeding on 3 different canola feeding aphids; mealy cabbage aphids, Brevicoryne brassicae (L.), mustard aphid, Lipaphis erysimi (Kaltenbach) and green peach aphid, Myzus persicae (Sulzer). The experiment was performed under laboratory conditions at 25± 1oC and 65 ± 1% RH. The immature development duration was shortest on M. persicae (17.3 days). While, C. carnea completed its immature developmental period in 21.1 days, which was longest among other, tested aphids. Similarly, survival of C. carnea was higher on feeding M. persicae and lowest on L. erysimi. Female egg laying of predator was also higher on M. persicae, followed by B. brassicae and L. erysimi. These results show that M. persicae favors the quick development and higher reproduction of C. carnea as compared to B. breassicae and L. erysimi. This information is useful in relation to mass rearing of C. carnea and in biological control of canola aphids by using C. carnea.

In this study, we developed 11 microsatellite markers specific to A. crataegi using NGS to investigate the genetic relationships of A. crataegi populations from South Korea to circumferential Asian countries (China, Russia, Mongolia, and Japan). Further, two mitochondrial DNA (mtDNA) gene segments (COI and CytB) were sequenced from the samples. The population- and individual-based Principal Coordinates and STRUCTURE analyses collectively suggested that the South Korean population of A. crataegi is most differentiated from the Japanese population, whereas it was closer to Mongolian and Chinese populations. These results collectively suggest that northern populations, in particular, Mongolian populations can be considered as the most genetically compatible one as donee population, when the reintroduction program is launched. †These authors contributed equally to this paper.

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.
