spotted-wing drosophila

Spotted-wing drosophila (Drosophila suzukii) is native to Asia but has emerged as an invasive pest in North America as well as South America and Europe in recent years. It is a particularly pernicious pest because it is attracted to not-quite-ripe or ripe fruit, and the female uses a serrated ovipositor to tear the fruit open and deposit its eggs. In a report published in September in Environmental Entomology, the researchers use data from more than half a million flies caught over 7 years to delve into the environmental conditions that drive the flies’ activity, timing, and abundance.
