Research Project: Manipulating Host & Mate-Finding Behavior of Plum Curculio: Dvlpmnt of a Multi-Life Stage Mgmnt Strategy for a Key Fruit Pest -Cfda #10.309

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

2010 Annual Report


1a.Objectives (from AD-416)
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 dected and mass spectrometry; (2) develop effective deployment strategies for newly identified olfactory stimuli to manipulate host- and mate-finding and promote aggreagation of the plum curculio within apple orchards; (3) evaluate efficacy of entomopathogenic nematodes against plum curculio larvae; (4) evaluate efficacy of a multi lifestage approach for management of plum curculio 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.


1b.Approach (from AD-416)
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 made in commercial orchards.


3.Progress Report

We have installed soil probes to measure abiotic conditions in soils in commercial orchards in New England (MA, NH, and VT). In each of six orchards, four units have been installed. Soil also has been collected from representative orchards to be used in bioassays evaluating efficacy of entomopathogenic nematodes against plum curculio larvae. The ADODR has monitored activities through emails, meetings, and calls.
