Chillo auricilius is pest of sugarcane causing decrease of production. Biology control utilizing eggs parasite Trichogramma japonicum was studied. This study aims to determine the suitability of Corcyra cephalonica eggs which was parasitized with Trichogramma japonicum on stem borer (Chilo auricilius) and to determine number of eggs of the rice moth (Corcyra cephalonica) which was most effective as alternative host. The experiment was conducted at laboratory of Agronomy Research Center of Sugarcane Plantation of Jatitujuh, West Java. Indonesia.  The experiment was arranged in a completely randomized design with a factor consisting of six levels (number of parasitized C. cephalonica egg: 150, 300, 450, 600, 750, 900 eggs. Each level was added with 100 more eggs of C. auricilius) and they were replicated thrice. Parameters were: Correlation between meteorological and larva emergence; parasitized eggs; larva emerged; and period of larva emergence. Correlation analysis and Anova were applied. The results showed that humidity were correlated with larva emergence (R² = 0.7147). The treatment P6 resulted the highest parasitized (95.33%) and the lowest (3%). T. japonicum was effective parasitoid to control sugarcane borer, and C. cephalonica was suitable to be the alternative or the intermediate host to guaranty the availability and sustainability of host at all the time.
