The Basics of Quality Control for Insect Rearing2015 Norm Leppla University of Florida Entomology and Nematology Department
I. Introduction Norm’s Career in Insect Rearing • University of Arizona- Insect rearing research, 2 years • USDA, ARS- Insectary management, Florida and Texas, 17 years • USDA, APHIS- Methods development, Washington DC and international, 7 years • University of Florida- Integrated pest management and biological control, 18 years • Rearing and quality of Tamarixia radiata (Chris Kerr) • Extension IPM (http://ipm.ifas.ufl.edu)
Quality Control Topics • Introduction- Learning how to rear quality insects • Colony Establishment and Maintenance • Monitoring Quality • Evaluation and Management • Guidelines for Quality Systems • Total Quality Management
Learning How to Rear High Quality Insects • Apprentice in an insectary • Network with other professionals • Literature plus trial-and-error • Visit other insectaries • Reviews by experts • Education and training programs

Generic Guidelines for Quality Systems • Policy, Planning and Administration • Design Assurance and Change Control • Control of Purchased Materials • Production Quality Control • User Contact and Field Performance • Corrective Action • Employees- Select, Train and Motivate
Quality Control Programs • Individual Companies Customers • International Standards ISO 9000 ASTM • The Marketplace Quality Products
Specifications- Requirements for a product or service Standards- The level of quality at which a specification is written

“Insect rearing is never a boring task; insects are always doing something interesting and pose new challenges all the time” Annie Lorie Punky Rogers Medium-Scale Rearing
Mass Rearing- Medfly El Pino, Guatemala Capacity- 3.5 billion sterile male pupae per week Metapa, Mexico
II. C. Options for Colonizing Insects Peter Ebling Insect Producer Database Mgr. Great Lakes Forestry Centre 1219 Queen St. East Sault Ste. Marie, ON P6A 2E5 peter.ebling@nrcan.gc.ca (705) 541-5517
World-wide listing, 35 insect & 21 nematode orders • Data submitted by sources • Searchable database • Expand clients • Adopt-a-colony http://www.insect.glfc.cfs.nrcan.gc.ca
Field Collecting Cabbage Loopers Trichoplusiani
II. D. Maintaining the Quality of Colonized Insects • Collection of appropriate biotypes • Colonization and strain development • Rearing proficiency • Colony management (SOPs) • Select, infuse, hybridize • Strain replacement Sam 2005
Colony Management • Maintain- Low productivity, variability, expensive • Select- High productivity, uniformity, consistency • Infuse- Short term recovery, hybridize? • Hybridize- New strain, crosses • Replace- New strain, adaptation
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 required stage • Rate of Development-Synchronization • Viability- Emergence, sex ratio • Size- Weight or measurements • Fecundity- Oviposition and egg hatch • Adult Behavior-Flight, longevity • Field Performance- Achieve purpose
Standardized QC Tests • Joop van Lenteren (2003), IOBC- Guidelines for quality control of commercially produced natural enemies, 30 species • Rose Buitenhuis (2014), Grower guide to quality assurance of biocontrol products, 22 species • Custom, develop your own, site-specific
Number of Cabbage Looper Pupae Per Rearing Container Shelf 1 is lowest
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

III. C. Production, Process and Product Control
IV. Evaluation and Management IV. A. Structured Diagnostic Procedures IV. B. Quality Control Versus Methods Improvement IV. C. Periodic Review
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 maintain 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
