The present study was conducted for efficient and quality production of stingless wasp, Trichogramma chilonis Ishii on grain moth, Sitotroga cereallela (Olivier) and rice meal moth, Corcyra cephalonica (St.). Biological control offers effective alternatives for the control of many insect pests. The most favorable temperature was 28 ºC on which maximum rate of parasitism and adult emergence were obtained from S. cereallela eggs as compared to C. cephalonica eggs. Under no choice test, the percentage of oviposition and adult emergence was the highest at 2 h eggs of both hosts. For host density...
