nor T h W e S T native buzz in WSU vineyard research plants, vineyards can host indigenous insects that will enhance biodiversity and often find feeding opportunities among vineyard pests. These include pollinators such as clearwing b flies as well as parasitoids that attack caterpil- lars and worms. Various Anagrus species are helpful in the control of leafhoppers and vine mealybug. A few of the spiders helpful in leaf- hopper control are attracted by the grasses in- cluded in some cover crop mixes. Evidence in- dicates that mallow may help control cutworm by being an attractive but toxic food source for larvae of the pest. The benefits of native species are the subject of a three-year proj- oosting habitat for beneficial insects is one of the ancillary benefits of having a native cover crop.

"The project will address the Washington winegrape industry priorities of reducing syn- thetic chemical inputs, improving integrated pest management and implementing sustain- able farming practices that protect the en- vironment and community as a whole," the project's abstract states.

James hopes to evaluate the perennials for practicality as cover ect that Dr. David James, an associate entomologist and extension specialist at Washington State University-Prosser, is launching in col- laboration with other WSU researchers. Plots of native plants at four vineyards in Eastern Washington will recreate patches of the local sage crops as well as the ability to attract and host beneficial insects. He also hopes to evaluate populations in conventional vineyards and those with restored habitat as well as engage with growers to enhance knowledge of integrated pest management systems. —P.M. 56 Wines & Vines FeBRUARY 201 1
