Research Project: **Location:
                            Temperate Tree Fruit and Vegetable Research** Project Number: 2092-22430-003-005-T
                        
                        Project Type: Trust Fund Cooperative Agreement Start Date: Jul 1, 2020
                        
                        End Date: Jun 30, 2024 **Objective:**
                        
                        1) Determine if volatiles emitted by post-dormant (bud-swell) pear trees are attractive to post-diapause winterform pear psylla. 2) Identify pear tree volatiles that are responsible for attraction of post-diapause winterform pear psylla. 3) Develop a synthetic lure, based on attractive pear tree volatiles, that can be used in a trap to detect, monitor, or manage migrating post-diapause winterform pear psylla. **Approach:**
                        
                        Volatiles will be collected from pear trees in early to late spring and identified using gas chromatography (GC), GC-mass spectrometry (GC-MS), and GC-electroantennogram detection (GC-EAD).Compounds identified will be synthesized or purchased for lure formulation. Attraction to pear volatiles by post-diapause winterform pear psylla will be assayed using GC-EAD, Y-tube olfactometry, and field assays.
