Research Project: Effects of Hermetic Storage on Red Flour Beetle Acoustic Activity Patterns and Mortality

Location: Insect Behavior and Biocontrol Research

Project Number: 6036-22000-030-57-N
Project Type: Non-Funded Cooperative Agreement

Start Date: Feb 1, 2018
End Date: Feb 28, 2019

Objective:
The objective is to monitor the effects of low oxygen on red flour beetles, Tribolium castaneum, activity and mortality to assist farmers with small storage facilities in estimating the durations of hermetic storage needed to reduce red flour beetle activity to levels below which negligible damage occurs to stored wheat.

Approach:
Different numbers of insects will be placed in containers containing different volumes of grain and will be stored under hermetic conditions to provide varying durations over which oxygen decreases below levels that sustain insect life. Acoustic detection and recording equipment will be used to monitor the daily decrease of insect activity as oxygen levels decrease. Oxygen level will be monitored concurrently. Activity and oxygen level will be monitored until activity ceases, and the signals will be analyzed to consider when feeding has declined to levels below which negligible damage occurs to the grain.
