This publication describes what home and community gardeners can do to monitor and responsibly manage spotted wing drosophila in their tree fruits and berries.
Drosophila suzukii Matsumura (Diptera: Drosophilidae) are small invasive flies that in the past five years (2009-2014) invaded berry and stone fruit production regions in Europe and the Americas. Evolutionary adaptations, biological traits, and anthropogenic factors have contributed to its current status as a global pest. Females oviposit eggs into ripe...
Drosophila suzukii (Diptera: Drosophilidae), a pest of thin-skinned fruits, has been detected worldwide recently, with new locations of establishment determined annually since it first became a concern on continental North America in 2008. Drosophila suzukii females are different from most other drosophilids as being one of two known species capable...
A method for large quantity dsRNA production was developed since a small amount of dsRNA synthesized in vitro with commercial kits are used for small scale bioassay evaluations. Developing a large-scale production system for dsRNA is critical for practical RNAi application, especially for non-transgenic RNAi-based control. However, large-scale analysis or...
Knowledge of Drosophila suzukii's preference for an attractive trap design and bait can be used to improve detection and management of this new invasive fruit pest. Desired trap and bait attributes include: high D. suzukii capture and species specificity; early-season detection prior to significant crop damage; higher capture of females...
Drosophila suzukii was a known pest of berries, grapes, and stone fruits in East Asia for almost a century. Yet in recent years it has successfully migrated throughout the United States, Mexico, and Europe due to globalized fruit trade. The invasive success of D. suzukii is causing unrest for fruit...
Drosophila suzukii (Diptera: Drosophilidae) is a devastating pest that attacks thin-skinned stone and small fruit in all major production regions of the United States and worldwide. D. suzukii first appeared in the United States in 2008 and is believed to be native to Southeast Asia. This vinegar fly has a...
This detailed guide illustrates how to test fruit for the presence of the Spotted Wing Drosophila larvae by crushing the fruit, immersing it into a salt or sugar solution and examining the fruit debris for larvae and pupae.
Spotted wing Drosophila (SWD), Drosophila suzukii (Diptera: Drosophilidae), is a pest of small and stone fruits that is widely distributed across much of the United States, Canada, Europe and Asia. Unlike other members of the Drosophilidae that only lay eggs in overripe or rotting fruit, SWD infest ripening and ripe...
A tool to help commercial fruit growers identify early damage caused by spotted wing Drosophila (SWD) on blueberries (Duke), raspberries (Malahat), strawberries (Seascape), cherries (Bing, Montmorency, and Rainier), and grapes (Pinot Noir, Chardonnay). Includes photos showing each fruit type a day or two after egg laying, 3 to 4 days...
Blueberry production in Oregon is highly reliant upon the ecosystem services of native pollinators, which provide as much as a quarter of the total pollination services received by Blueberry growers. However, the health of these pollinator populations may be affected in yet unforeseen ways as growers adopt new pest management...
