A novel approach to controlling tree-destroying beetles uses piped-in rock music and backward recordings of Rush Limbaugh.
- Scientists believe they can combat insect damage by subjecting bark beetles to acoustic stress.
- Rush Limbaugh, heavy-metal music and the beetles' own calls were used in the studies.
- The research could lead to a chemical-free, environmentally friendly way to prevent insects from killing trees.
Beetles don't like heavy metal or Rush Limbaugh, suggests new research, but the sounds that really drive them mad are manipulated versions of their own noises.
Beetles are destroying ponderosa, pinyon, lodgepole pines and other trees important to the ecosystem. The beetles have their place in the ecosystem too, of course, but climate change and human activities have allowed beetles to take over more than they should.
To combat such infestations, scientists thought up the "nastiest, most offensive sounds" they could. Those included recordings of Guns & Roses, Queen, Rush Limbaugh and manipulated versions of the insects' own sounds.
