"The flies can put their eggs under it but it's very hard for the wasps to reach.". And there's a good reason for it, too. These insects, mainly of the family Tephritidae, are of economic importance. Secondary pests attack from other insects may also occur in the fruit. But outside the lab, these ubiquitous insects are masters at oviposition, or egg-laying. Using a simple Y-maze that had oranges in one wing and plums in the other, the researchers found that the wasps vastly preferred the scent of the plums. Attractant or trapping substance is put on twisted cotton about the size of thumb and then tied with a small wire such that it is hang in the middle of the tube traps. And last year, Hansson and his colleagues discovered that fruit flies have a single class of sensory neurons that are specifically tuned to detect geosmin — an odorant that alerts the fly to the presence of harmful microbes.
