Research Project: Detection and Analysis of Red Palm Weevil Acoustic Signals in Date Palm Orchards

Location: Insect Behavior and Biocontrol Research Unit

Project Number: 6615-22000-025-11
Project Type: Trust

Start Date: Mar 01, 2013
End Date: Feb 27, 2015

Objective:
1. Record vibrations produced by red palm weevil (RPW), Rhynchophorus ferrugineus, in Saudi Arabian date palms, and identify signal features of greatest utility for distinguishing RPW sounds from typical background noises. 2. Analyze sounds produced in different species and in different parts of palms trees at different levels of infestation to consider ways of using acoustic detection methods to estimate RPW population levels within trees. 3. New hypotheses will be developed and tested jointly with colleagues about the best methods for detecting and eliminating RPW populations both in Saudi Arabia and in Caribbean areas from which there is now a threat of RPW invading southern Florida and southern California.

Approach:
These studies will be conducted with Saudi Arabian Ministry of Agriculture and University colleagues who will identify locations where the RPW are likely to occur and who will participate in the signal recording and analysis process. The colleagues will obtain corroborative physical samples from the palm trees. Saudi Arabia has locales with both high and low RPW density which will facilitate data collection and comparative analyses.
