Location: Fruit and Nut Research

2011 Annual Report

1a.Objectives (from AD-416)
In this project our overall objective is to develop and optimize strategies for using entomopathogenic nematodes for plum curculio. Specifically we will conduct laboratory screening of entomopathogenic nematode susceptibility of plum curculio and oversee field studies with entomopathogenic nematodes targeting this pest.

1b.Approach (from AD-416)
We will screen plum curculio in the laboratory for susceptibility to insect-killing nematodes. We will assist in overseeing implementation of field studies testing these nematodes. Briefly, we will conduct a series of laboratory assays to screen virulence among a variety of entomopathogenic nematode species and strains. Assays will be conducted at various temperatures that mirror those in the orchard. The most promising nematodes will be field tested for efficacy in suppressing plum curculio under trap-trees. Specialty Crops Research Initiative.

3.Progress Report

This project relates to inhouse Objective 1: Develop alternative control strategies of pecan weevil; determine efficacy of biocontrol agents; investigate basic biology and ecology.

Plum curculio is a key pest of stone and pome fruits. The project is aimed at developing an advanced pest management system for control of plum curculio. The Principal Investigator at the Byron station has initiated an extensive screening program to determine the best nematode for plum curculio control. The project promises to reduce chemical inputs and enhance sustainable agriculture.
