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.
