Ferrisia gilli, Gill’s mealybug, is a newly described species of mealybug that is spreading throughout pistachio production regions in California (Gullan et al. 2003). In the late 1990s, Gill’s mealybug was first found infesting pistachios near the town of Tulare in the southern San Joaquin Valley of California. By 2006 it had spread to at least 3,000 acres (1,214 ha) of pistachios in 11 counties (Butte, Colusa, El Dorado, Fresno, Glenn, Madera, Tulare, Sacramento, Shasta, Stanislaus, and Tehama). Gill’s mealybug has also been found, and occasionally caused problems, on almonds, grapes, persimmons, and stone fruits as well as several deciduous ornamentals such as fruitless mulberry.
