"Bug the bugs, then kill them!"

The Island of Guam became a living laboratory for scientists as they attached acoustic equipment to coconut trees in order to listen for rhinoceros beetles... the Guam Coconut Rhinoceros Beetle Eradication Project.

"This method of
acoustic detection allowed Guam 'rhino hunters' to quickly and efficiently locate feeding grubs in an area thought to be rhino-beetle free," says Aubrey Moore, "and as the beetle broadens its range the acoustic approach to detection may save money and the lives of many coconut trees." (more)

Oryctes rhinoceros (L.) (Coleoptera: Scarabaeidae: Dynastinae) causes economically important damage to ornamental and commercial coconut palm trees in the western Pacific region that could be mitigated significantly by early detection and treatment. Adults are difficult to detect visually because they attack the crowns of the trees and feed internally before mating and dispersing to new hosts. Visual inspection is nevertheless the most widely used detection method, augmented with pheromone traps. This species is an ideal candidate for acoustic detection because the adults are large, active borers that produce stridulations during courtship and mating. (more)

Fun to play with.
"For some weird reason, Japanese people love Rhinoceros Beetles. It is very common for a boy to have a beetle as a pet. They usually put them in little boxes and carry them around in their pockets. Used almost like a Pokemon, boys will whip out their beetles and make them fight each other. This vending machine sells Rhinoceros Beetles - Males for 300 yen, and females for 100 yen." (more)

hter, however. (video)
