Biology, ecology, and management of spotted wing drosophila.
A female fly penetrates fruit with its large serated ovipositor, leaving a small puncture wound. Infested fruit then becomes brown, soft, and sunken and will typically develop microbial growth at the puncture site.
The most important component of a management regime for SWD involves intensive monitoring for the presence of adult flies. Several homemade and commercial traps are available for SWD control, as well as several bait and lure formulations. Below is a list of extension resources detailing current management protocols for SWD from several states in different crops.
