Synthetic female decoys might be the next big thing in male insect zapping

When trying to curb the the spread of invasive insect species, one of the most important steps is actually being able to catch them. Typical traps, such as those use to catch the tree-ravaging emerald ash borer, use scents such as pheromones to attract males (males are easier to catch because of their mating behavior, which consists of following and landing on females). But scent-based traps aren’t ideal: they often require maintenance, and they don’t let researchers know exactly how many insects they’ve has caught.
Fortunately, a group of international researchers appears to have hit upon a brand new way of gaining male beetle’s attention: luring them with female decoys. And although the use of a visual cue is interesting on its own,…
