Formulation changes will be made to micronutrient levels and substitutions will be made for the fibrous, temperature sensitive and antibiotic materials in artificial diets as part of an empirical-based effort to improve artificial diets. Life history measurements will be used to assess the impact those dietary changes on the health of the insect. The impact of dietary component changes on the biochemical fate of nutrients will be monitored. Enzymatic activity and metabolism of nutrients will be used to assess the impact of dietary changes on the efficiency of nutrient absorbance and nutrient utilization. The use of genomic biomarkers as indicators of fitness for insects reared on diets varying in nutritional quality will be investigated. Differentially-expressed genes will be identified using suppressive subtractive hybridization and microarray analyses.
