Standard Specification for <span class="italic">Encarsia formosa</span> Gahan (<span class="italic">Hymenoptera:Aphelinidae</span>) (Withdrawn 2017)
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.
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.
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.
WITHDRAWN RATIONALE
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.
Formerly under the jurisdiction of Committee E35 on Pesticides, Antimicrobials, and Alternative Control Agents, this specification was withdrawn in January 2017 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
