As cherries begin to ripen on backyard fruit trees, you'll want to monitor the fruit for pests, especially an invasive species called the spotted wing drosophila (Drosophila suzukii).
The spotted wing drosophila (SWD) is a new pest to California (since 2008). It's a small fly that attacks ripening cherries, and may also attack ripening raspberry, blackberry, blueberry, and strawberry crops, especially in coastal areas. When conditions are right, the fly can also attack soft-fleshed fruit such as plums, plumcots, nectarines, and figs.
If your cherry tree has SWD, you might notice that fruit flesh has one or more small punctures or “stings” on the surface. These symptoms are evidence of the eggs laid...

In observance of National Pollinator Week, we thought we'd share how you can manage pests around your home, garden, and landscape and still protect pollinators.
Natural enemies (predators, parasites, and pathogens) reduce pest populations and help prevent damage to plants. Pollinators such as domesticated honey bees, wild bees, and other pollinating insects, are essential in the production of many of the fruits, vegetables, and nuts we grow in California, both in our backyards and in commercial agriculture.
Natural enemies and pollinators can be harmed by pesticides...

Spotted winged drosophila (SWD), Drosophila suzukii, is a fruit fly that first arrived in California in the late 2000s and now is present throughout most of the state (Figure 1). It can attack various berry crops including strawberries, raspberries, blackberries, and blueberries; however, in backyards most complaints come from gardeners who grow cherries.
Unlike other fruit flies that attack fruit only after it has ripened and is starting to deteriorate, SWD attacks healthy fruit on the tree.../span>
