  • The potential of two entomopathogenic nematodes, Sreinernema carpocapsae Pocheon strain and Heterorhabditis bacteriophora Hamyang strain as biological control agents was evaluated against mushroom ny, Lycoriella mali in laboratory and field. Mortality of L. mali was significantly different according to nematode species, concentration, temperature, and developmental stage of fly S. carpocapsae was more effective than H. bacteriophora. Mortality of L. mali was higher at $25^{\circ}C$ than at $20^{\circ}C$. In addition, the 3rd instal and the 4th instar of L. mali were more susceptible than the 2nd instar. The lowest $LC^{50}$ value was represented by S. carpocapsae, 20.0 infective juveniles (Ijs) in the 3rd instar, 27.5 Ijs in the 4th instar at $25^{\circ}C$. S. carpocapsae infected all the developmental stages of L. mali except egg stage and the 1st instar of larva. The highest mortality was shown in adult female representing 74.0% at$20^{\circ}C$ and 80.0% at $25^{\circ}C$.L. mali female adult was influenced by S. carpocapsae in oviposition. The number of eggs by L. mali female infected by nematodes was much lower than uninfected females. S. carpocapsae was dispersed by infected L. mali adult with higher numbers by females than males. When S. carpocapsae was applied at the rate of $2.25{\times}10^{5}\;and\;4.5{\times}10^{5}\;Ijs/1.5\;\textrm{m}^2$ in the mushroom house, mortalities were 42.2% and 81.6%, respectively. The infective juveniles of nematodes survived for 14 days in the mushroom medium. However, nematodes did not affect mushroom growth.

  • King oyster mushrooms are one of the major fresh agricultural products which their exports are increasing every year in Korea. Lycoriella ingenua, is notorious insect pest in agriculture, especially in mushroom production. Larvae of L. ingenua cause mainly direct crop damage and adults are vectors of several dangerous fungal pathogens. In this study, the effects of electron beam, X-ray, and gamma-ray irradiation on the development and reproduction of L. ingenua were evaluated. In addition, to find the optimal dose to control L. ingenua in a box filled with king oyster mushrooms, an empirical experiment was conducted for each radiation. As a result, the development and reproduction of L. ingenua were inhibited at 50 Gy for all electron beam, X-ray, and gamma-ray irradiation. Additionally, at the top, middle, and bottom of the export box filled with king oyster mushrooms, the development and reproduction of L. ingenua were inhibited by electron beam with 150 Gy, X-ray with 100 Gy, and gamma-ray with 50 Gy. These results can be provided as basic data for establishing an integrated quarantine management system when exporting mushrooms. It will also contribute to the safety of agricultural products and the strengthening of export competitiveness.

  • During cultivation of Pluerotus ostreatus, there were happened several problems by mushroom flies. Many mushroom farms were faced with the problem that mushroom production periods became shorter by mushroom fly. In this study, we examined effect of Lycoriella ingenua on the production of P. ostreatus. When we used 10 adult flies at the time of inoculation, mushroom production decreased by 10.8% as compared to that of the control. And when L. ingenua used more than 20 adult flies, contamination occurred in all treatments. And when L. ingenua used at the time of P. ostreatus mycelium cultured during 14 days, it was confirmed that the yield of P. ostreatus decreased in proportion to the number of L. ingenua.

  • Among flies inside mushroom growing rooms in three farms, Lycoriella ingenua and Megaselia tamilnaduensis were the most common and dominant species during Pleurotus ostreatus cultivation in Korea. In the past, generally, during the incubation period, a low density of mushroom flies was observed in all farms. After the first harvest, mushroom flies density tended to increase sharply. However, many mushroom flies were observed in the summer, despite that season corresponds to the incubation period. This is because annual cultivation systems provide a safe overwintering place compared to seasonal selective ones. The ecology of mushroom flies varies greatly according to the cultivation system. We confirmed that a fallow period reduced the density of mushroom flies. From a survey of the three dimensional distribution of mushroom flies in a growing room, we observed that M. tamilnaduensis showed more positive phototaxis and a higher variation per point of capture than that by L. ingenua. Through this study, two mushroom fly species were identified in the survey farms, with markedly different three dimensional distribution patterns.

  • We used the entomopathogenic nematode, Steinernema carpocapsae, for the effective biological control of Lycoriella mali during Agaricus bisporus cultivation. The concentrations of two S. carpocapsae products distributed in Korea were $6{\times}10^4$ and $2.5{\times}10^5m^{-2}$ respectively. As a result of investigating the density of A. bisporus larvae in a rice straw medium and soil in an A. bisporus cultivation house, the mean numbers per $30cm^2$ were 0.8 and 22.2, respectively, and A. bisporus larvae were detected mainly in the soil. The control effects after once spraying S. carpocapsae at $6{\times}10^4$ and $2.5{\times}10^5m^{-2}$ was higher at the 14th day than at the 7th day. Therefore, we investigated the control effect after twice spraying of $6{\times}10^4$ and $2.5{\times}10^5m^{-2}$ at the 14th day. The control effects after this spraying were 51.9% and 96.8%, respectively, and the control effect of spraying at $2.5{\times}10^5m^{-2}$ was better than at $6{\times}10^4m^{-2}$. The control effect of diflubenzuron WP was lower than 50%.

  • A Sciarid fly, Lycoriella mali was a serious pest in commercial production of the cultivated mushroom, Pleurotus ostreatus. It was found in light trap and compost samples taken from mushroom houses during all growing seasons. The fly population 'was increased with the development of mushroom growth, the larvae occurred about 30 days after spawn inoculation in compost. The highest population was developed spring cultivation season (March to June) and decreased during summer season (August to September). The larvae feed on mycellium and compost; injury to the growing mushroom mycellium and the subsequent consumption of the primordia; they entered and tunneld sporospore stem and infect pinhead formation which would be resulted in decrease of mushroom yield.

  • Mushroom sciarid fly Lycoriella ingenua (Dufour), syn. L. mali (Fitch) is one of the most common fly pests affecting the mushroom cultivation in Korea. This study was carried out to investigate the development at different temperatures and damages of L. ingenua in A. bisporus mushroom cultivation. Rearing of mushroom flies were carried out on mycelial culture in Petri dishes. The development of L. ingenua from egg to adult at the temperature of 16, 20, 24, $28^{\circ}C$ were 35.2, 25.8, 23.5, and 22.2 days, respectively. Adult flies invade mushroom farms and oviposit in freshly spawned compost. Damages are mainly caused by the larvae of 1-7 mm, which feed on growing mycelium and also developing stipes and caps of mushrooms. Adult flies spoil the appearance of the fruiting bodies, spread various fungal and bacterial disease, and transmit mites. The damages by mushroom flies increased without pest control causing yield loss of up to 27%.

  • The thirteen commercial insecticides to Lycoriella mali were investigated on their insecticidal activities and mycelial growth of two Letinula edodes strains. For the adults, insecticides showing over 95% insecticidal activity were chlorpyrifos-methyl, fenthion, fenitrothion, benfuracarb, furathiocarb and deltamethrin. For tile larvae, diflubenzuron and cyromazine showed over 90% insecticidal activity. Fenthion, benfuracarb, furathiocarb, deltamethrin, diflubenzuron and cyromazine did not affect the mycelial growth of L. edodes strain, in Imhyup 1 variety. And deltamethrin, diflubenzuron and cyromazine did not affect that in Sanlim-5. Insecticides showing over 80% residual effect for 14 days were benfuracarb to the adults and diflubenzuron and cyromazine to the larvae. Control effect of furathiocarb, fenthion, benfuracarb, deltamethrin, diflubenzuron and cyromazine against larvae of Lycoriella mali showed 90% ten days after application under sawdust cultivation. Among them, benfuracarb, fenthion and furathiocarb revealed excellent control effect against adults. These results indicate that benfuracarb, fenthion, and furathiocarb can be used for the control of Lycoriella mali in the field. However, further studies are needed on the effect of insecticides treatment oil fruit-body yield and chemical residue in the mushroom tissues.

  • The dark-winged fungus gnats are one of the most serious fly pests attacking the mushroom cultivation in Korea. They cause severe damage to the artificial sawdust beds used to cultivate mushroom, and reduce the production of button mushroom, Agaricus bisporus, in greenhouses. In this study, we collected nine species of the mushroom flies in order to identify the dominant species of the dark-winged fungus gnat attacking the A. bisporus plantation using the yellow sticky trap in Buyeo-gun, Boryeong-gun, Yongin-si and Chilgok-gun from April to June 2015. The collected samples were used to determine the DNA sequence of the cytochrome c oxidase subunit I (COI) of the nine different species by DNA barcoding. The sequencing results showed that Lycoriella ingenua was the dominant dark-winged fungus gnat species destroying A. bisporus cultivated on the artificial sawdust beds in Korea.
