Research Project: Development of Handling, Transport and Release Methods for Sterile Navel Orangeworm (Amyelois transitella)

Location: Commodity Protection and Quality Research

Project Number: 2034-43000-043-024-A
Project Type: Cooperative Agreement

Start Date: Jun 1, 2020
End Date: Jul 1, 2021

Objective 1) Improve handling, transport and release methods for shipping insects from the Phoenix Mass Rearing Facility located in Phoenix, AZ to the field sites in Fresno, CA. 2) Develop an automated insect transport magazine developed for auto-dosing insects at predetermined insect by biomass/acre. 3) Determine optimal release height and swath width. 4) Develop and prepare vehicle storage of unmanned aircraft system (UAS) and release magazine for future robotic automation. 5) Assess the viability of UAS for releasing sterile navel orangeworm.

Objective 1, Develop and test a system to replace current passive cooling in the existing transport magazine with an air conditioning system controlled with feedback obtained from Internet of Things enabled sensors tracking insect container temperature once per minute during transport. The air conditioning system and sensors will target temperatures will be identified through bench studies to assess the impact of torpor throughout the handling, transport and release process. Objective 2, Develop a system of a scale and an auger can be programmed to automatically dose a set number of insects by mass and acre into a release device designed to release sterile NOW. This will be used with insect mass data recorded at the sterile release facility to precisely deliver a target overflooding ratio. Objective 3, Swarm technology (the ability to simultaneously release from 3 UAS at 3 altitudes) will be used to minimize variation due to environmental variables (wind speed, temperature, and relative humidity) to determine optimum height and swath width for UAS and compare to currently-used manned aircraft. Objective 4, Robotic developed in previous M3-APHIS projects will be examined to determine if the handling, transport and release of sterile NOW prior to loading into aircraft (manned or UAS) can be improved to reduce worker exposure to scales while maintaining or improving quality of sterile insects.
