Infectivity of entomopathogenic nematodes and fungus was evaluated against fly larvae in the laboratory and outhouses. Mortalities of Muscina stabulans larvae were 96.7f 2.8% in Steinernema glaseri Dongrae strain, 90.0+0.0% in S. carpocapsae All strain, 86.7f 2.7% in Heterorhabditis bacteriophora Hamyang strain, and 70.0+9.4% in S. carpocapsae Pocheon strain on the filter paper. When 260, 000 nem\ulcornertodes were sprayed into the outhouses, H. bacterwphora Hamyang strain killed 100%, S. glaseri Dongrae strain killed 76.9+3.9%, and S. carpocapsae Pocheon strain killed 58.5+6.1% of maggots. When 130, 000 nematodes and 7.0X lo9 cfu of entomopathogenic fungus, Beauveria brongniartii were sprayed alone or combined into outhouses, mortalities of maggots were 73.6+0.1% in B. brongniartii alone, 77.8+3.9% in S. carpocapsae Pocheon strain plus B. brongniartii, and 77.7f 5.1% in H. bacteriophora Hamyang strain plus B. brongniartii. Entomopathogenic nematodes and fungus were potential biological control agents in this study.
