On June 30, 2022 the San Mateo County Agriculture Department pest detection team found a single Oriental fruit fly (Bactrocera dorsalis) in a baited trap in Menlo Park. The team followed up with a delimitation survey that includes 40 traps within one square mile of the find. This is in addition to 80 existing traps within the 8 square miles surrounding the find. No new Oriental fruit flies have been detected. Oriental fruit flies are an invasive pest native to southern Asia, that has become established in Hawaii. It is a pest to over 230 different kinds of fruit and vegetables threatening California’s $50 billion dollar agricultural industry.
