New Scientist has an interesting bit today on how the small hive beetle has been able to penetrate beehives. While the pests have been observed infiltrating honeybee home security systems, and killing off bees for about a decade now, scientists have been puzzled by how they've managed to get past the security detail. That is, until now. Apparently, the beetles are tapping into the same alarm pheromone that makes the bees go crazy. So, once "the levels of the chemicals in the hive go up, worker bees become disoriented and yet more beetles arrive for dinner." It's a sneaky system for sure, but seems towork devastatingly well.
