Research Project: Improving and Verifying Quality of Mass-Reared Navel Orangeworm for Sterile Insect Technique

Location: Commodity Protection and Quality Research

Project Number: 2034-43000-043-030-T
Project Type: Trust Fund Cooperative Agreement

Start Date: Dec 9, 2020
End Date: Dec 31, 2021

1. Characterize chill injury and chill recovery. 2. Evaluate recapture and field competition of Phoenix facility mass-release sterile navel orangeworm (NOW). 3. Support M3 to develop sterile moth shipping and release methods

1. Experiments will test the effect of age of first exposure to cold on survival of NOW and performance on flight mills. 2. Field experiments will compare current overflooding (marked sterile moths/unmarked moths) and recapture rate (marked sterile moths recaptured/marked sterile moths released) with similar data from previous years in mating disruption and non-mating disruption release sites. 3. Data from Objective 1 will be used to determine if milder holding conditions could improve survival and flight cylinder performance.
