Data for: A small survey of introduced African fig fly (Zaprionus indianus) (Diptera: Drosophilidae) in orchards of the eastern United States

The African fig fly, Zaprionus indianus (Gupta), is a generalist fruit fly that typically breeds in decaying fruits from over 70 plant species. The species has spread globally from its native range in tropical Africa, becoming an invasive pest on ripening figs in Brazil. First reported in the United States in 2005 in Florida, Z. indianus has since been documented as far north as Canada and is hypothesized to recolonize northwards from southern refugia each year. We sampled drosophilid communities over the growing season at two orchards in Virginia from 2020-2022 and 11 orchards along the East Coast during the fall of 2022 to quantify abundance of Z. indianus relative to other drosophilids across locations, seasons, and fruit crops. Massachusetts was the northernmost population, with no Z. indianus detected in Maine and no correlation between latitude and relative abundance. Variation in Z. indianus relative abundance was high between nearby orchards and abundance was higher on peaches r..., Field collections of wild Drosophilids were conducted by netting/aspirating/trapping flies at various orchards. Flies were sorted to identify species as Z. indianus or not and counts of Z. indianus and non-Z. indianus (other) were recorded., , # Data for: A small survey of introduced African fig fly (Zaprionus indianus) (Diptera: Drosophilidae) in orchards of the eastern United States *** This dataset contains counts of wild Drosophilids collected from locations in the eastern United States from 2020 to 2022. All flies were identified as Z. indianus or other species.
