African fig fly (Diptera: Drosophilidae): Biology, expansion of geographic range, and its potential status as a soft fruit pest
Journal of Integrated Pest Management 10 (1 - 20)
Abstract: African fig fly, Zaprionus indianus Gupta (Diptera: Drosophilidae), is originally from the Afrotropics but has been expanding its geographical range globally, including the United States. It was first reported in Virginia northward in 2012. The current established range of African species is thought to be limited to the southern states in winter, and populations must disperse northward each season. Adults are normally caught in Virginia in mid-summer and later. African fig fly is a competitive invader and affects the dynamics of native drosophilid communities when it invades a new area. While lacking the hardened, serrated ovipositor seen in spotted-wing drosophila, another invasive frugivore, it may come to outnumber that species in commercial plantings. It can lay eggs and develop in many kinds of fruit that have been otherwise injured. However, the ovipositing fly may take advantage of oviposition sites of spotted-wing drosophila, thereby allowing entry of African fig fly larvae, which may outcompete the original inhabitants. Furthermore, African fig fly may be able to infest certain soft-fruit hosts. Biological control in North America and Europe is limited at this time by immunological responses of host larvae; naturally occurring parasitoids have been unable to achieve significant parasitization.
