Tracking Beetles using Sound —

<p>The Coconut Rhinoceros Beetle is an invasive species that if left alone would decimate citrus crops across California. To prevent this from happening, John Allen and his team at the University of Hawai'i have been working to hunt the insects down before they are able to reach the West Coast of the USA. By identifying the frequency of the beetles wing beat, they are able to track them down by listening out for the unique flapping sound of their wings and alert pest control to their whereabouts.</p>
