Research Project: Manipulating Host and Mate-Finding Behavior of the Plum Curculio: Development of a Multi-Life Stage Management Strategy

Location: Appalachian Fruit Research Laboratory: Innovative Fruit Production, Improvement and Protection

Project Number: 1931-21000-024-02
Project Type: Reimbursable

Start Date: Sep 01, 2009
End Date: Aug 31, 2014

Specifically, we will: (1) isolate and identify attractive olfactory stimuli associated with host- and mate-finding for adult plum curculio using gas chromatography coupled with electroantennogram detection (GC-EAD) and mass spectrometry (MS); (2) develop effective deployment strategies for newly identified olfactory stimuli to manipulate host- and mate-finding behavior and promote aggregation of the plum curculio within commercial apple orchards; (3) evaluate efficacy of entomopathogenic nematodes against PC larvae; (4) evaluate efficacy of a multi-life stage approach for management of PC within spatially precise locations within commercial apple orchards; and (5) actively promote outreach and information exchange among interested stakeholders, crop consultants, state IPM research and extension programs, and federal researchers.

We will utilize laboratory-based electrophysiological studies and field-based bioassays to identify novel olfactory stimuli for the plum curculio. We will also perform laboratory- and field-based studies to identify effective entomopathogenic nematodes. Final evaluations will be conducted in commercial orchards.
