Project Type: Specific Cooperative Agreement

Start Date: Jul 01, 2011
End Date: Dec 31, 2013

Objective:
Trade barriers exist on the import of apples and cherries from the Pacific Northwest based on the presumed risk of temperate fruit flies entering and establishing in export market countries. A multi-faceted or systems approach taking into account potential fly distribution, fly detection, and fly identification components are addressed in this project. In this project we plan to evaluate potential fly distributions through modeling, evaluate attractants for flies, evaluate methods to discriminate closely related fly species, and to develop collaborations for modeling risk of infestations in orchards.

Approach:
Determine critical parameters (i.e. photoperiod, chilling requirement) for diapause induction and completion in apple maggot from Washington State. We will include obligate diapausing, cafultative diapausing, and putative non-diapausing portions of AM populations. Determine critical parameters for growth and development of apple maggot and Western cherry fruit fly under climatic conditions specific for tropical regions.
