520 _aAsian corn borer (Ostrinia furnacalis) is a main pest in Indonesia and other countries. Studies to develop the control method of maize or corn borer using natural enemies were caried out. Two parasiteoids against Ostrinia furnacalis i.e. Trichogramma evanescens andBeauveria bassiana were tested in laboratories and field conditions. In the laboratory, releasing of 15, 30, and 45 individual T. evanescens per maize plant increased parasiteized O. furnacalis eggs to 45, 78, and 82 percent, respectively. Releasing T. evanescens weekly for 3 to 5 times at 4 to 8 weeks after planting and once at the time of one egg mass per 30 plants with the number of 250,000 parasiteoid/ha/applications could parasiteize O. furnacalis egg ranging from 52 - 92 %, compared with 33% at the control. The parasiteoids only infected one and two day old eggs, but did not infect three day old eggs. A T. evanescens female could infect 9-65 eggs (average 34.67 eggs) of O. furnacalis. Field observation showed that 37.5% to 100% (average 80.4%) of O. furnacalis eggs were parasiteized by T. evanescens. Laboratory study indicated that inoculation of B. bassiana spores at the concentration of 5 x 107 to the larvaes of O. furnacalis resulted in 62% infection. Application of the spores at the concentration of 104-7 could reduce the infection of O. furnavalis 15 to 20%. Both T. evanescens and B. bassiana are prospective biological control agents for maize stem borer O. furnacalis in Indonesia.
