Research Project: Areawide Pest Management (AWPM) program for navel orangeworm control in almonds, pistachios, and walnuts

Location: Commodity Protection and Quality

Project Number: 0500-00044-035-03
Project Type: Specific Cooperative Agreement

Start Date: Aug 01, 2008
End Date: Jul 31, 2013

Objective:
To validate and demonstrate areawide management approaches for the navel orangeworm in tree nut crops grown in the northern region of California’s central valley.

Approach:
In collaboration with USDA-ARS scientists at the San Joaquin Valley Agricultural Sciences Center, Commodity Protection and Quality Unit, we will work with stakeholders in the Sacramento Valley to validate and demonstrate navel orangeworm management spproaches including cultural controls (sanitation, destruction of ground mummies, andearly harvest), improved timing of reduced risk insecticides, and mating disruption. In order to successful accomplish this, we will validate and modify parameters (if necessary) for risk assessment in northern tree nut growing regions of California including navel orangeworm overwintering survival in mummy nuts remaining on trees and on the ground, contribution of nearby navel orangeworm sources to load in commercial orchards, incidence of navel orangeworm damage in the presence of other kernal feeders, and navel orangeworm degree-days.
