Biological control of turfgrass insect pest Blitopertha orientalis, forest insect pests, Agelastica coerulea, Meganola melancholia, and Glyphodes perspectalis,vegetable insect pests, Plutella xylostella and Agrotis segetum were conducted with entonopathogenic fungus, Metarhizium anisopliae J-22 isolated from black pine forest soil in Cheju province. Mortality of B. orientalis larvae was 53.3% at the rate of 3.4 $\times$ 1O 7 conidia /ml. A. coerulea and M melancholia larvae showed 100% mortalities at 9.6 $\times$ 106 conidia /ml and 2.7 $\times$ 10 7 conidia /ml as well. However, G. perspectalis larvae were not dead even at 4$\times$ 1O 7 conidia /ml. On the other hand, M anisopliae J-22 was effective against P. xylostella larvae showing 100% mortality at 4 $\times$ 10 7 conidia /ml.

Mortality of some agro-forest insect pests, Agrotis segetum, Blitopertha orientalis, Agerastica coerulea, Glyphodes perspectalis and Acantholyda parki caused by entomopathogenic nematodes was investigated in laboratory and in pot. Steinernema carpocapsae All and Pocheon strain were effective against 2nd of 3rd instar larvae of A. segetum showing 100% mortalities at the concentration of 10Ijs/larva but not effective against 4th inster larvae. Mortality of B. orientalis was 100% after 26 days in H. bacteriopora NC 1, H. bacteriophora Hamyang and S. glageri NC strain treatment. S. monticulum also showed 100% mortalities against A. coerulea andd G. perspectalis at the concentration of 80 and 40 Ijs/larva. However, H. bacteriophora Cheju and S. glaseri Cheju strain were not effective against A. parki, i.e., showing 23.3 and 20.0% mortalities, respectively at the concentration of 160Ijs/larva. S. glaseri Hanrim strain was more effective than H. bacteriophora Cheju strain against Pryeria sinica.

Seasonal and regional occurrence of oriental beetle, Blitopertha (=Exomala) orientalis was investigated using pheromone traps and soil sampling at three golf clubs in Busan, Gunpo, and Gimpo from 2004 to 2007. Adults of Blitopertha orientalis were found from early June to late August, but peak times were different depending on the location and year. Peak day of adult occurrence of B. orientalis was 25 June,2006 and 22 June 2007 in Busan, but 30 June,2006 and 29 June,2007 in Gunpo. Mean numbers of B. orientalis adults attracted to pheromone trap varied with locations. Larval development was faster in Busan than in Gunpo. The 2nd instars of B. orientalis was found on 27 August, 2004 in Gunpo whereas 3rd instars were found in Busan in the same period. In Busan, overwintered 3rd instars pupated from early May to mid-June and emerged from early June. Eggs laid at this time were hatched from late June Most 3rd instars were found at middle August and started to overwinter. The peak time of mating was 20:00 to 22:00 hour of the day.

A pathogenic nematode, Butlerius sp., was isolated from Oriental beetle, Blitopertha orientalis. The infective juveniles exhibited dose-as well as time-dependent entomopathogenicity on the larvae of B. orientalis. Two bacterial species, Providencia vermicola (KACC 91278) and Flavobacterium sp. (KACC 91279), were isolated from the infective juveniles and identified. P. vermicola outnumbered Flavobacterium sp. in the nematode host, in which the colony density of P. vermicola was found to be 21 times higher than that of Flavobacterium sp. However, when the two bacterial species were cocultured in culture media without the nematode host, they showed similar growth rates. Both bacteria induced significant entomopathogenicity against Spodoptera exigua larvae infesting economically important vegetable crops, where P. vermicola was more potent than Flavobacterium sp.

Biological control of forest insect pests, Agelastica coeruleci, Meganola n~elancholia,a nd Glyphodes perspectalis, turfgrass insect pest, Blitoperfhu orientr~lis,v egetable insect pests, Plutella xylostella and Agrotis segetun~ with entomopathogenic fungus, Beciuveria hassinna GY 1 - 17 isolated from rice paddy of Yangsan in the southern part of Korea were investigated. Mortalities of A. coeruleu and P. ~ylo.~rellluar vae were 100% at the rate of 7.0 and 2.0 x 107conidia/ml after 7 and 5 days and those of M. melancholia were 66.7 - 100% at the rate of 0.03875-3.1 X 107conidia/ml. However, G. perspectulis was not affected at the rate of 2.0 x lo7 to X I04conidia/ml. And mortalites of B. orientcilis and A. segetum larvae were 46.7% at 3.7 x 107conidia/ml and 63.3% at 2.5 X 107conidia/ml.

Occurrence ecology and possibility of mass trapping of Popillia quadriguttata, one of the most serious turfgrass insect pest in domestic golf courses was investigated using pheromone traps in Gimpo and Jinhae. Peak period of adult occurrence of P. quadriguttata was late June and early July in Gimpo Seaside Country Club from 2006 to 2008. It was early and middle July in Youngwon Country Club in 2006. The first catched day of P. quadriguttata adult was 20 June, while the last day was 10 September in Gimpo Seaside Country Club, 2006. Mean catched number of P. quadriguttata adult in Japanese beetle pheromone trap per day in peak period of occurrence were 18.2, 25.7, 29.0, and 15.7 at 2005, 2006, 2007 and 2008 respectively. Mean catched number of P. quadriguttata adult in Japanese beetle pheromone trap were more in fairways or roughs than tees or greens. Possibility of control of scarab beetle using pheromone trap with pesticide treatment was investigated against oriental beetle, Blitopertha orientalis in Dongrae Benest Golf Club. Mean number of dead oriental beetle adult were more higher(2.9 folds) in fenitrothion EC treatment than fenitrothion EC treatment after set oriental beetle pheromone trap.
