III. Monitoring Quality III. A. Quality Control Criteria and Standardized Tests III. B. Sampling for Consistent Quality III. C. Production, Process and Product Control
III. A. Quality Control Criteria and Standardized Tests • Quantity- Number of Pupae or Adults • Size- Weight of Pupae • Fecundity- Oviposition and Egg Hatch • Rate of Development-Synchronization • Adult Behavior-Flight, Longevity • Field Performance- Achieve Purpose
Specifications- Requirements for a product or service Standards- The level of quality at which a specification is written
III. B. Sampling for Consistent Quality Count = Measurement = N Mean = Sum/Number of Counts = X Variance = Sum of (N – X)2 / n-1 = 2 Standard Deviation = Square Root of 2= SD

IV. A. Structured Diagnostic Procedures
IV. B. Quality Control versus Methods Improvement Quality Control • Monitor indicator variables • Evaluate multiple variables • Troubleshoot using QC data • Conduct evaluations rapidly • Goal is to restore stable production Methods Improvement • Conduct evaluations methodically • Test one variable at a time • Use controlled experiments • Test results in the production system • Goal is to optimize production
Improving Male Fruit Fly Performance Abiotic Environment • Holding Cages • Handling for Release Biotic Environment • Juvenile hormone • Nutrients (sucrose) • Semiochemicals
