Development of an Optimum Diet for Mass Rearing of the Rice Moth, Corcyra cephalonica (Lepidoptera: Pyralidae), and Production of the Parasitoid, Habrobracon hebetor (Hymenoptera: Braconidae), for the Control of Pearl Millet Head Miner

Two sets of three experiments were conducted to evaluate dif- ferent diets for production of C. cephalonica. The first experi- ment consisted of five treatments: 1) 100% pearl millet, 2) 50% pearl millet + 50% sorghum, 3) 50% pearl millet + 50% cowpea, 4) 50% pearl millet + 50% peanut, and 5) 25% pearl millet + 25% sorghum + 25% cowpea + 25% peanut. The second experiment was set up based on the results of the first experiment. For this experiment, the diets were prepared from a combination of flours of pearl millet and cowpea with the fol- lowing proportions: 1) 100% pearl millet, 2) 50% pearl millet + 50% cowpea, 3) 75% pearl millet + 25% cowpea, and 4) 95% pearl millet + 5% cowpea. Data included number of living and dead larvae of C. cephalonica, number of C. cephalonica emerging moths, number of eggs and number of emerging H. hebetor offspring.
