More than a decade after its arrival in the continental U.S., spotted-wing drosophila has spread to many parts of the country. But a decade of research has built a broad knowledge base for a variety of management strategies. A new review in the Journal of Economic Entomology provides an in-depth analysis of the current state of SWD management and promising future directions.
For the invasive fruit fly known as spotted wing drosophila, its success in expanding into new ranges is driven at least in part by a high degree of phenotypic plasticity—the ability to shift traits in response to environmental influences.
A food-grade gum substance shows promise as a new tool for managing the invasive spotted-wing drosophila. The flies don't get stuck, but the scent interferes with their reproductive behavior, and the gum can last up to three weeks in the field.
Seven years' worth of trapping data for the invasive spotted-wing drosophila in Michigan offer an enhanced view of the pest's seasonal activity and abundance patterns, a boon for fruit growers and integrated pest management pros in temperate regions.
The African fig fly (Zaprionus indianus) is an invasive fruit fly in North America that has been found commingling with its cousin spotted-wing drosophila (Drosophila suzukii), sometimes even using the latter's egg-laying sites for its own. A new profile in the Journal of Integrated Pest Management highlights the African fig fly's biology and range and offers options for management.
