Significance and Use
This method was developed to determine that the numbers of E. formosa supplied in a shipment meet the package claim and that wasps at receipt have good flight capability. The application of this method will ensure a standardized evaluation of the product and judicious decisions about product compliance to the package claim.
Abstract
This specification covers information on and the test method for determining the purity and number of adults released in shipments of Encarsia formosa Gahan (Order Hymenoptera; Family Aphelinidae), parasite of the greenhouse whitefly, Trialeurodes vaporariorum Westwood. Because the efficacy of the biological control of greenhouse whitefly by E. formosa depends on accurate release numbers of adult species, accurate packaging and maintenance of purity and viability of E. formosa shipments is, therefore, essential for the effective management of the target pests. This specification is intended for use by the producers and end-users of the specified biological control agent.
Scope
1.1 This specification describes a method for determining whether the quantity and quality of adult Encarsia formosa in a shipment adhere to quantity and quality specifications. The test also allows the purity of shipments to be determined. Included are referenced documents, a description of standard terminology, specifications, and the test method.

What is a Redline?
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
additions
deletions
and other changes between the two standards.
Save Time and Trouble!With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
PriceWhen you select the "Standard + Redline" option you get both documents! Best of all, the cost of a Standard + Redline is only slightly more than buying the Active Standard by itself.
