Wildfire is one of important disturbances in forests, which may effect on insects distribution. In Sangju, about 13 haof pine forests was burned in March, 2017. We investigated the response of insects to fire severity in burned pine forests,Sangju. Study area was classified by fire severity as 5 classes, such as unburned, light, light-moderate, moderate-severe,and severe. We placed 4 multi-funnel traps in each fire severity class. A total of 729 insects belonging to 42 specieswere collected during May 24 to October 12, 2017. Spondylis buprestoides (447 individuals), Sipalinus gigas (50 individuals),and Acanthocinus carinulatus (43 individuals) were dominant species accounted for 74.1% of total. According to fire severity,abundance and species richness were increased with fire severity, especially in high-medium area. Interestingly, two Monochamusspecies, vector insects of pine wood nematodes, were more caught in more severed area than in other classes.

Korea has been importing large quantities of plant materials from countries annually all over the world. Accordingly,various kinds of pests have been also detected during import inspections. In addition, these days the weather in Koreahas been getting warmer and a number of imported subtropical and tropical crops are being cultivated in greenhouses.In these regards, conducting a monitoring survey by using pheromone traps is required in order to prevent introductionand settlement of invasive species to Korea. we provide a list of insects collected from five types of pheromone trapscollected while monitoring exotic pests over the last seven years. Data from the monitoring surveys of pheromone trapsfrom 2010 to 2016 was extracted from database of the Plant Quarantine Integration System (PQIS) developed by theAnimal and Plant Quarantine Agency (APQA). As a result of our review on the PQIS database, 119 species were identified.The families forming the main groups are Tephritidae, Tortricidae, Camillidae and Cosmopterigidae. We believe that researchersand inspectors in charge of quarantine need to be well aware of the species collected from monitoring traps.

Epipleminae is the most species-rich lineage within Uraniidae and can be characterized by its unusual resting posture.Since Leech (1897) first reported two species, Epiplema moza (Butler, 1878) and Gathynia fasciaria Leech, 1897, therehave been 5 genera and 9 species of Epipleminae recorded from Korea (Sohn & Yen, 2005). We reported three speciesof Epipleminae new to Korea: Dysaethria meridiana (Inoue, 1982), Phazaca theclata (Guenee, 1857), and Europlemaleleji Sinev, 2016. Taxonomic status of Europlema leleji Sinev is revised. A revised checklist of the Korean Epipleminaeis provided.

Biological activities of bombolitins from Bombus ardens, B. consobrinus, B. terrestris and B. ussurensis (bombolitinsA, C, T and U, respectively) were examined using hemolytic, anti-microbial, anti-fungal and anti-tumor activity assays.Among the four bombolitins tested, bombolitin T showed the highest hemolytic and anti-tumor activities. All bombolitinsexhibited strong anti-microbial and anti-fungal activities, and bombolitin A specifically possessed the highest anti-microbialactivity against the Gram-negative bacteria Escherichia coli. Circular dichroism spectrometry analysis revealed that allfour bombolitins had over 61.7% and 45.5% of α-helicity in 30 mM sodium dodecyl sulfate and 50% trifluoroethanolbuffers, respectively, which form lipid-membrane-mimicking environments. Bombolitin T showed the lowest IC50 valuesof 8.5 μM and 8.8 μM against SK-OV-3 and NIH-OVCAR-3 cell lines, respectively, after 72 h of treatment, but itsrelative hemolytic activity at a concentration of 200 μM was 2.3-fold higher than that of 0.1% Triton X-100. Thisstudy provides new information on the biological and molecular properties of venom peptides of bumblebees. However,further studies on reducing cytotoxicity of bombolitins are needed for designing selective anti-tumor peptides.

In this paper, two species of Mirine plant bug, Pinalitopsis rhodopotnia Yasunaga, Schwartz and Cherot, 2002 andYamatolygus pilosus (Yasunaga, 1992) are newly recorded from Korean peninsula. The dorsal habitus and genital structureof each species were provided. Also, figure of allied species, Pinalitus nigriceps Kerzhner, 1988 and P. rubeolus (Kulik,1965) are also documented to aid in the identifications of allied species.

West Nile Virus (WNV) is transmitted by infected mosquitoes. Vector mosquitoes usually acquire these pathogens fromfeeding on an infected host, and transmit the pathogens to a naive host during feeding events. To understand the virustransmission dynamics and to survey WNV throughout country, the present study has been conducted. We collected mosquitoesat urban parks in Seongnam, Wonju, Gunsan, Daegu, and Tongyeong using CDC light trap with Dry ice from April toSeptemper in 2017 (mosquito collecting is on going). Among collected mosquitoes, blood-fed mosquitoes were conductedblood meal identification assay and the other mosquitoes were subjected to virus detection using real-time PCR method.A total of 2,290 mosquitoes representing 6 genera and 15 species were collected. The most dominant species was Culexpipiens complex (42.1%) followed by Aedes albopictus (15.1%), Ae. vexans nipponii (14.6%), Ochlerotatus koreicus (9.8%),Cx. orientalis (6.5%), and Armigeres subalbatus (4.4%). The blood meal source were of mammal (93.3%), and birds (6.7%).So far, no WNV has been detected in any mosquitoes.

The members of the genus Flavivirus are noteworthy, as they cause infectious diseases in humans, such as Zika, denguefever, yellow fever, West Nile, and Japanese encephalitis. Due to the increased awareness of the public health risk posedby flavivirus-infected mosquitoes, mosquito collections were performed in six urban parks of South Korea, as the parksare designated for human recreation but also provide suitable habitats for mosquitoes. We examined the diversity andabundance of mosquito species and conducted molecular diagnostics for the detection of flavivirus infections. Monthlycollections were carried out in each park from March to August in 2017. A total of 4,851 mosquitoes (5 genera and13 species) were collected using BG-sentinel traps and then investigated for flavivirus infections. Pathogenic flavivirusinfections causing human diseases were not observed in the field-collected mosquitoes. However, insect-specific flavivirus(ISF) infections were detected in several mosquito pools. ISF has been previously known to enhance or suppress the replicationof medically important flaviviruses in co-infected mosquito cells. In this study, partial sequences of ISF were analyzed.However, further studies are needed in order to determine its genetic characterization and biological function in vivo.

Lepidoptera, one of the major herbivore groups on terrestrial ecosystems, have evolved various feeding habits on theirhostplants. Diversification of feeding habits has led to their success in the extant fauna. However, there have been limitedstudies scrutinizing evolutionary patterns of such diversification (Kaila et al., 2011; Regier et al., 2015; Sohn et al., 2016).Leaf-mining is the major form of lepidopteran endophagy, occurring in at least 34 families (Hering, 1951). Leaf miningis considered a primitive trait in Lepidoptera because it characterizes the basal (non-ditrysian) lineages, while the derivedDitrysia and Macrolepidoptera trend strongly toward external feeding (Connor & Taverner, 1997). In contrast, internalfeeding is restricted to relatively derived lineages in other insect orders. This contrasting pattern may be a key for understandingthe evolutionary history of Lepidoptera. We discuss this issue based on two lepidopteran leaf-mine fossils discovered lately.

Fumigation activity of Frankliniella occidentalis, western flower thrips, and phytotoxicity were evaluated with phosphine(PH3) and ethyl formate (EF) in the asparagus. Fumigation activity of PH3 and EF showed in the order of egg (64.7 mg·h/Land 132.9 mg·h/L), nymph (5.5 mg·h/L and 14.8 mg·h/L), and adult (3.8 mg·h/L and 14.7 mg·h/L) respectively at 5˚C in12 L desiccator. The adsorption of PH3 was 24% at 5˚C. However, the adsorption of EF increased sharply to 98% at 5˚C.PH3 showed 100% control for all development stage of F. occidentalis with 4g/m3 in 0.65m3 at 2˚C for 48h exposure. Thephytotoxicity was not found. The results revealed that the EF is highly absorbable in asparagus, so it is not suitable as afumigant, but PH3 is considered to be suitable as an alternative MB fumigant for control of the F. occidentalis in asparagus.

Based on a research proposal from Cambridge University that knowing the anatomical structure of the insects wouldhelp make an excellent biomimetic robot, we studied the anatomical characteristics of insects for application to jumpingrobots. We choose crickets, grasshoppers, and mole crickets among the Orthoptera. The external and muscle microstructuresof the three insects were compared using a stereomicroscope, an optical microscope and an electron microscope. Musclefiber bundles of the third legs of the grasshoppers and crickets were very dense, although their mitochondria numberswere smaller than their first leg. Muscle fibers of the first legs of the mole crickets are more loosely arranged than grasshoppersand crickets’ first legs, and there is a large number of different sized mitochondria, although the distinction between musclebundles is not clear.

The effects of Postharvest CO2 treatment on the quality and shelf life of oyster mushroom packaged with oriented polypropylene (OPP) film bag were investigated. On the day of harvest, the ‘Gonji-7ho’ oyster mushroom grown by bottle cultivation of Jangheung County, Korea transferred to a laboratory in Wanju County and were cooled in a cold room at 3°C for 1 day and then treated with 30% or 50% CO2 for 3 hours at 3°C. After the CO2 treatment, 400 g of oyster mushroom were sealed into 20 μm thick OPP film bag (width: 29 cm, length: 24 cm) used in the actual farmhouse. The package gas composition, hardness, color change, off-flavor index, browning index, and overall quality were evaluated during storage at room temperature (RT) for 6 days and at 3°C for 21 days. As a result, During storage at RT, the concentration of carbon dioxide in the bag of 30%, 50% CO2 were higher than untreated and shelf-life of oyster mushroom at 50% CO2 was reduced 1 day due to off-flavor while 30% CO2 or untreated was 2 days. During storage at 3°C, the concentration of carbon dioxide in the bag was kept low at 30%, 50% CO2 treatment compared to untreated, the respiration of oyster mushroom at 30, 50% CO2 were lower than untreated during initial 7 days storage at 3°C, but ethylene production were not different. The hardness of oyster mushroom at 30% CO2 was higher, the lightness (L* value) of stem surface was higher, the yellowness (b* value), browning index was lower and odor index was lower than untreated or 50% CO2. 30% CO2 treated oyster mushroom packaged with OPP film bag kept 4.2~16.2% O2 and 4.2~15.5% CO2 concentration in the bag during storage at 3°C, and showed highest overall quality index. Marketable shelf-life was assessed 10 days for untreated, 17 days for 30% CO2, and 16 days for 50% CO2, respectively.

Flammulina velutipes belonging to white rot fungi is one of the commercially important edible mushrooms and is produced in large quantities due to the introduction of a automated and mechanized cultivation system in Korea. Despite the chief item of export among edible mushrooms, Flammulina velutipes has the lowest distribution rate of domestic cultivar, estimated that about 20 percent. As the result that most white cultivars of Flammulina velutipes produced and exported in Korea were introduced from Japan, farmers pay a large amount of royalties. Therefore, we try to develop a new pure domestic cultivars as a substitute for Japanese cultivars. To breed both white and gold superior strains, we selected the crossing mother groups including 10 white strains of ASI 4198 etc. and 7 brown strains of ASI 4049 etc. and mated each of the 17 strains by mon-mon hybridization. 19 white and 14 brown strains were chosen through two selection experiment over 2014 2016. In the third selection experiment this year, we finally selected one white(Fv 16 c 37) and the other gold(Fv 15 a 31) strain. Two selected strains were cultivated in the same environmental conditions. Spawn running period on the sawdust substrate required 30days at 20°C. The cultivation period and optimum temperature were 12±1 days at 14°C for primordia formation, 5 days at 4°C for inhibition phase, and 14±1 days at 7°C for fruiting body development. The length of pilei and stipes in two selected strains and Megumi as a control Japanese cultivar harvested in optimal stage was as follows: 10.5±0.81mm and 139.7±4.23mm in Fv 16 c 37, 10.8±0.43mm and 128..2±7.31mm in Fv 15 a 31, and 10.9±0.41mm and 141.8±4.64mm in Megumi respectively. The Yield of Fv 16 c 37, Fv 15 a 31 and Megumi was 271.2±11.84g, 237.7±9.05g and 270.7±16.87g per 1100ml in bottle cultivation.

The Pleurotus tuoliensis is a mushroom named Chinese ‘Bai-Ling-Gu’ from species of Pleurotus nebrodensis. we are mated for selection of cytoplasmic hybrid by mitochondria microsatellite marker and the method of Mon-Mon mating between monokaryotic strains derived from Pleurotus ferula ASI 0629 (Beesan No.1) and Pleurotus tuoliensis ASI 0663 (Baekryung 20). The cytoplasmic hybrids were identified 8 strains contained nuclear DNA bands of 'Baekryung 20' and mitochondrial DNA of monokaryon strains derived from Pleurotus ferula ASI 0629 (beesan No.1). The KiMB-Plft-15-81 was shown the best cultural characteristics, selected to be a new cultivar and designed as 'Baekwhang'. The 'Baekwhang' cab be grown without an extra after-ripening period, can utilize bottle cultivation of Pleurotus eryngii. And also the ‘Seolwon’ is similar to the existing Pleurotus tuoliensis in shape and physiological characteristics, formed high stipe. We therefore expect that this new strains will substitutional goods of Pleurotus eryngii.

There are three kinds of Pleurotus eryngii : P. eryngii var. eryngii (P. eryngii), P. eryngii var. ferula (P. ferula : A-Wei-Mo) P. eryngii var. nebrodensis (P. nebrodensis : Bai-Ling-Gu). We bred P. ferula using Di-Mon mating and physiological assay and selected as follow (1) ‘Beesan No.1’ produced high yields, (2) ‘Beesan No.2’ was excellent morphological shape and anti-adipogenic Activit, (3) ‘Ergo’ included high ergothioneine such as anto-oxidant material, (4) ‘GW10-45’ included highest ergothioneine such as anto-oxidant material, (5) ‘Maeksong’ included high ergothioneine and effect of anti-inflammatory. We suggest that there are able to food-medicine materials.

Volvariella volvacea is mainly cultivated in subtropics area like South-East Asia. Because it is cultivated in rice straws, it is called a straw mushroom. That mushroom grows well in high temperature about 30~38°C and high humidity. Straw mushroom is a homothallic mushroom, so it is difficult to identify whether the offspring is different from the parents. This study was carried out to investigate RAPD primers that can be used for identification the DNA polymorphism of Volvariella volvacea genetic resources. 9 strains were collected from various countries like China, Vietnam etc. When ITS regions of their DNA were analyzed, they proved to be Volvariella volvacea. A cultivation test was conducted to measure the morphological characteristics of them 2 strains, KMCC04380 and KMCC04382 were selected for breeding resources because the mycelium of them grew well on medium and fruiting bodies were formed quickly. The Universal PCR Fingerprinting kits(UPF primers) were used to confirm the genetic polymorphisms of the 2 strains. As a result of confirming the DNA bands, 2 of 12 primers could be used to genetically distinguish 2 strains. About 50 spores were isolated from their fruiting bodies respectively and they also will be confirmed DNA polymorphisms by using UPF primers.

The production scale of mushroom cultivation in Korea is approximately 600 billion won, which is 1.6% of the Korean gross agricultural output. Annually, ca. 190,000 tons of mushrooms are harvested in Korea. The oyster mushroom is one of the most favorite and commonly consumed mushrooms in Korea. In case of breeding, the protoplast fusion technique of the oyster mushroom, P. ostreatus was first commercialized in the world. To develop the high temperature varieties, various examinations were accomplished. Protoplast fusion of abalone mushroom, high temperature, and oyster mushroom, popular mushroom, were attempted. 2 strains of P.ostreatus and 2 strains of P.abalonus were fused to each other by protoplast isolation. Fusion strains were investigated by random amplified polymorphic DNA(RAPD) marker, and selected strains were cultivated at 25°C after completing the mycelial growth. As a result of sawdust bag cultivation, most of strains showed the fruiting body, but the morphological characteristics among them were not significant different. However, these protoplast fusion strains were expected as new parents strains to develop varieties.

A new commercial cultivar ‘GARES-HM-17-1’ of Hypsizigus marmoreus was developed by the method of mono-mono crossing between monokaryotic strains derived from Hae-Sal 3Ho. The parental strains are characterized by the property of high quality and a short period of time in cultivation. The optimum temperature of mycelial growth was 25°C and that of fruiting body development was 15~16°C. The period of harvesting including primordia formation was 23.0 days shorter than that of control strain Mangadak No. 2. The color of pileus and stipe surface was neutral-white, respectively. The yield was 82.0±5.8g/850cc plastic bottle. Analysis of the genetic characteristics of the new commercial cultivar ‘GARES-HM-17-1’ showed a different profile as that of the control strain, Mangadak No.2, when RAPD (Random Amplified Polymorphic DNA) primer was used. This new cultivar ‘GARES-HM-17-1’ of H. marmoreus is characterized by the improved quality and a short period of time in cultivation after scratching. It would be of much help to expand the cultivation area of H. marmoreus.

H. mamoreus is a mushroom with abundant favor and medicinal use. However, its cultivation has problems such as the long cultivation period, low biological efficiency and microbiological contamination, so new cultivars should be developed. In this study, 55 strains of H.marmoreus were analyzed with ISSR markers to identify precise genetic information in collected germplasm as mother strains in breeding. ISSR 13 and 15 markers were confirmed polymorphism. The three strains (KMC03106, KMC03107, and KMC03108) with white cap color were close genetic relationship in the UPGMA analysis of both the ISSR 13 and 15 markers. Especially in the PCR result of the ISSR 15, the collected germplasm were differentiated to three groups following collecting year. As these results, the ISSR 15 marker would be able to classify the phylogeny of cap color and genetic variation along the collecting year. Therefore ISSR markers will confer effective selection of mother strains for breeding of H. mamoreus.

Information and communication technology(ICT) around the world in the 21st century presents a new vision of agriculture. Time, place, and the high-tech industry to overcome barriers to the fusion of the so-called “smart agriculture” is changing the landscape of agriculture. Precision Agriculture’s core container production for the mushroom cultivation temperature, humidity, irradiation, self-regulation, such as carbon dioxide, the optimal environment for mushroom cultivation was implemented. The Lentinula edodes (shiitake) is an edible mushroom native to East Asia, which is cultivated and consumed in many Asian countries. It is considered a medicinal mushroom in some forms of traditional medicine. The fungus was first described scientifically as Agaricus edodes by Miles Joseph Berkeley in 1877. It was placed in the genus Lentinula by David Pegler in 1976. We controlled different light source (Blue-Red-White combined LED, blue LED, red LED and fluorescent light) with different intensity of LED irradiation (1.5, 10.5, 20.5 μmol/m2s for LEDs) to compare growth and development. Lights were treated with 12 hour on/ 12hour off cycle maintained in a controlled room with 19 ~ 21oC temperature, 80~90% humidity, and 1,000 ppm CO2 atmosphere concentration for 30 days. Growth and development differed from the LED color source and intensity of LED irradiation. Growth and development was most effective in 10.5 μmol/m2s for blue LED. All LED light sources showed less growth and development in lowest intensity of irradiation, which indicates that higher than 1.5 μmol/m2s for LED is not effective. After harvesting fruit bodies, we measured their weight and length, thickness of pileus and stipe, chromaticity, and hardness. 10.5 μmol/m2s blue LED group was the best result of harvest with average individual weight (24.7g) and length (61.98mm), thickness (29.93mm) of pileus and length (33.60mm), thickness (16.86mm) of stipe with fine chromaticity, hardness. This results show us that 10.5 μmol/m2s blue LED was the best effect on growth and development of Lentinus edodes (shiitake) mushroom’s ICT system container type environment.

This study is investigated the growth characteristics(number of available stipe, pileus diameter, pileus thickness, stipe length, stipe thickness, object weight, comparison yield ability of 1 cycle) and storage characteristics of ‘Sanjo 701’ (S7) cultivars according to relative humidity. The S7 growth characteristics were investigated by quantifying the growth and the characteristics according to the relative humidity, The storage stability was investigated every 5 days and freshness was measured by ‘Minamide Method’. S7 pileus diameter is The higher the relative humidity was confirmed becomes larger and the more increased relative humidity also increase the comparison yield ability of 1 cycle. However, pileus diameter or stipe length This could not see the big difference in the three treatment groups, the plieus thickness was no significant difference in the treatment of 80% and 95%. The fresh weight of S7 decreased significantly at 80% and 95% relative humidity after 10 days of storage, but decreased continuity in 65% humiditiry. The elongation percentage of S7 pileus was observe in 95% relative humidity, values of L, a and b (SCI), showed the highest L value in 65% and the a value in 95%. b values were similar in 65%, 80% and 95% treatments. On the ‘Minamide Method’ measure freshness was changed from the 10th day of storage at relative humidity of 95%, but humidity of 65% and 80% treatments, it changed after 15 days of storage. In this study growth characteristics and yield were increased at higher relative humidity, but storage stability was decreased. Therefore, it is deemed necessary to change the relative humidity to produce high quality mushrooms.
