Assessment of damage to sugarcane caused by the sugarcane moth borers confirms the success of C. Jlclvipes 111 controlling population of sugarcane moth borers complex. The percent infestation of sugarcane by larvae of sugarcane moth borers complex are illustrated in Figure 4. It reveals that the infestations were very high in the first period of growth of sugarcane in every plot. After parasites were released, infestation levels decreased and low peak occurred during July to December at both location. The average percent infestation in release and control plots at Kanlpaeng Saen were 8.65 and 12.9, 5.77 and 10.65 and 5.38 and 14.62, while at Sai Yok were 6.39 and 12.6, 5.71 and 14.41 and 4.85 and 13.66 in 1995, 1996 and 1997 respectively (Table 2). Average percent infestation in release plots was significantly different from those in control plots at both locations, and was lower than results reported by Suasa-Ard and Charernsom (1995).
