Early identification of fruit fly pest saves cherry crop

Andy is a Central Coast cherry grower. In May 2009, he brought samples of cherries infested with a maggot to show UCCE farm advisor Bill Coates. Coates quickly saw that this was an unfamiliar pest that could pose a serious threat to the local cherry industry. He sent the samples to the California Department of Food and Agriculture for expedited identification, and immediately began to work on a monitoring and control program based those he had used for fruit flies. Because this was a previously unknown pest with a sudden onset, the pest—identified as the spotted wing drosophila—caused significant crop damage that first year in many Central Coast cherry orchards. But thanks to the efforts of Bill Coates and other UCCE specialists and advisors, just a few short years later the industry had a robust commercial monitoring program and good pest control measures in place.
