This study was conducted to develop environmentally friendly control techniques to reduce chestnut insect pests. The study sites were selected in intensive chestnut orchards of Jinju city, Gyeongnam province. In early and middle-ripening cultivars of chestnut tree, the damage of chestnut fruits by Dichocrocis punctiferalis was significantly lower in wromstop than other treatment such as wromstop+wood vinegar, Capture-machine (p<0.05), While there was no significant difference among treatments in late-ripening cultivars. The hight control effect for D. punctiferalis was showed the highest in wromstop treanment with 40.49% and 41.89% in early and late-ripening cultivars. The control effects for Curculio sikkimensis in late-ripening cultivars of chestnut tree were 34.59% in wromstop imidacloprid treatment and 28.94% in air control treatment.

This study was carried out to develop environmental friendly control for major diseases and pests on Boxthorn (Lycium chinense Mill.). Outbreak of Eighteen diseases and pests were found at the Boxthorn organic yards in Chung-nam province. Among them Powdery mildew (Erysiphe polygoni de Cand.), Hypophyllous mold (Pseudocercospora chengtuensis (Tai)), Western flower trips (Frankliniella occidentalis (Pergande)), Green peach aphid (Myzus pericae (Sulzer)) and Corn earworm (Helicoverpa armigera) needed to be controled by environmental friendly methods for high fruit yield of organic Boxthorn. In summer(Jun) test Bacilus subtilis QST 713 wettable powder and Sulfur wettable powder were effective and in autumn (Sep.) test Sulfur, Copper hydroxide and Paraffinic oil were relatively effective in Powdery mildew. In Hypophyllous mold control test Paraffinic oil and Bacilus subtilis GB - 0365 were effective with above 70% control value. And it was possible to control Western flower trips by natural enemy (Orius laevigatus) by 80% control value. Corn earworm was possible to control by Bacillus thuringiensis subsp. aizawai GB413 flowable and Bacillus thuringiensis aizawa 0423 wettable powder application above 70%. And Green peach aphid was controllable with environmental friendly materials, such as, Bacillus subtilis (Seoncho), Bacillus subtilis (Jinsami) above 80% and Ginkgo nut extract above 70% control value.

This research was performed to test the effects of oleic acid for the management of greenhouse whiteflies and tobacco whiteflies. Tobacco whiteflies, especially, are the vectors of tomato yellow leaf curl virus on tomato plants. Whiteflies are not only the vectors of various viruses but also the major insect pests that cause direct damages through sucking and induce sooty mold with their sweet dew on tomato plants. There are many eco-friendly management measures including the use of yellow sticky trap and natural enemies such as Eretmocerus eremicus and Amblyseius swirskii. However, these management measures have difficulties to implement in the greenhouse. Therefore, in this research, oleic acid was tested for its effect on the management of whiteflies at various concentrations of 1,000ppm, 2,000ppm, or 4,000ppm. As a result, treatments of 1,000ppm, 2,000ppm and 4,000ppm oleic acid showed the control value of 70%, 76% and 84%, respectively. In another test, treatments of 2,000ppm oleic acid, and control treatment of 1,5000ppm neem oil and 50ppm dinotefuran showed the control value of 82%, 75%, and 75%, respectively. Cost for one application of oleic acid and neem oil for 10a area would be 3,180 Won and 20,150 Won, respectively. As a result, it was assumed that the use of oleic acid would be a appropriate management measure.

To evaluate light-emitting diode (LED) as potential attractants for Bemisia tabaci adults, attractiveness of white and yellow LED traps were investigated in greenhouse. The yellow LED trap showed the most attractive to B. tabaci adults, followed by a similarly attraction to the white LED trap, whereas the control (no light trap) was little attractive to B. tabaci adults. These results suggested that yellow and white LED traps could be used for environment-friendly insect pest control.

Two experiments were designed and executed to measure the effectiveness of the two-fluid fogging system in controlling whiteflies in tomato cultivation. The two-fluid fogging system that lowers temperature and raises humidity in greenhouses provides an eco-friendly method of preventing damages from whiteflies. The first experiment elucidated the effect of fogging treatment on the elimination of whiteflies and investigated the sectional distribution of whiteflies. The second experiment analyzed the vertical distribution, the motility of whiteflies and reduction of the number of whiteflies under the fogging system. The result of the experiments showed that the fogging system lowered the number of whiteflies and decreased their motility significantly. It affected the vertical distribution of whiteflies as well. Based on these experiments, we strongly recommend using the fogging system to prevent and control whiteflies in greenhouses, in addition to installing yellow sticky traps in the areas that have the highest density of whiteflies.
