Project Type: Interagency Reimbursable Agreement
Start Date: May 15, 2018
End Date: May 14, 2023
Expand testing of novel biorational products to determine the potential efficacy of: 1. Elucidate behavioral mechanisms that define entomopathogenic nematode (EPN) dispersal and infection. 2. Elucidate chemical signaling that underlies EPN dispersal and infection behaviors. 3. Leverage knowledge on behavioral and chemical ecology to enhance biological pest suppression using EPNs.
Objective 1: Trials will be conducted to determine if aggregative dispersal is continuous or temporal, and whether nematodes display “follow-the-leader” behavior. Objective 2: liquid chromatography–mass spectrometry (LC-MS) based technologies and fractionation and Nuclear magnetic resonance (NMR) will identify bioactive active, which will be verified through bioassay. Objective 3: In laboratory and small field plots, chemical signaling compounds will be added to nematode suspensions to determine potential for enhanced pest control.
