  17. Purposes for Rearing Insects

  18. Types of Insect Rearing Systems Blister Beetles Medflies

  19. Parasite and Predator Rearing

  20. Maintaining the Quality of Colonized Insects • Collection of appropriate biotypes • Colonization and strain development • Rearing proficiency • Colony management • Behavior-genetic selection • Strain replacement

  21. Quality Control Criteria • Quantity- number of pupae & adults • Size- weight of pupae • Fecundity- oviposition & egg hatch • Rate of Development- synchronization • Adult Behavior- flight & longevity • Field Performance- achieve purpose

  22. Determining Standard Deviation Number (n) = measurement Mean (X) = sum n’s/number n’s Variance (V) = sum of squares (X-X)2 Standard Deviation (S) = square root of V

  23. Global QC Programs • Individual CompaniesCustomers • International StandardsISO 9000 ASTM (Amer. Soc. for Testing & Materials)IOBC Guidelines (European Community) • The MarketplaceQuality Products

  24. Insect Rearing and Quality Control References • Rearing of Insects (Encyclopedia of Insects, 2002) • The Basics of Insect Rearing (Encyclopedia of Entomology, 2004) • Guidelines for quality control of commercially produced natural enemies (Quality Control and Production of Biological Control Agents, Theory and Testing Procedures, 2003). • The Foundation of Quality Control for Insect Rearing (Principles and Procedures for Rearing Quality Insects, Mississippi State University, 2006)

  25. Challenges for the Commercial Biological Control Industry • Expertise • New Markets & Products • Science and Technology Improved rearing and release methods Field tests to determine efficacy Compatibility with pesticides Taxonomic support Quality control • Regulations

  26. World Markets for Natural Enemies vs. Pesticides Microbials $158,000,000Arthropods 40,000,000Total $198,000,000Pesticides ~$30,000,000,000

  40. Conclusions- Amblyseius swirskii • Very high numerical responseto availability of food • Highly efficacious against western flower thrips, greenhouse whiteflies and tobacco whiteflies • In combination with: • Orius spp. against western flower thrips • Whitefly parasites against whiteflies • P. persimilis or A. californicus against two-spotted spider mites • Good establishment on pollen • Whiteflies can substitute for pollen in peppers • Good results in North and South Europe • May replace A. cucumeris, depending on release permits
