The drought may be driving more invasions by annoying insects such as ants, but not necessarily for the reasons one might expect.
Many people are asking, “Why are there so many more pests this year than usual?”
People may just be seeing more pests, according to an urban integrated pest management (IPM) advisor with UC Division of Agriculture and Natural Resources.
“The overall abundance of pests probably hasn't changed and may even have decreased as compared to wet years,” said Andrew Sutherland, Ph.D., urban IPM advisor for the San Francisco Bay Area. “The real questions we should be asking are ‘Why are these pests appearing earlier in the year?' and ‘Why are the pests appearing all at once as opposed to throughout the year?'”
“This is also the first year we've seen dramatic changes made by residents due to mandated water-use restrictions,” Sutherland said. “Areas with frequent irrigation and lush landscapes aren't available this year so nuisance pests like outdoor cockroaches, ants and crickets are migrating from dry areas to seek moisture.”
This search may lead the thirsty pests to homes, garages or landscape that they haven't visited before. The IPM advisor used oriental cockroaches as an example.
“Oriental cockroaches are highly dependent on moisture and humidity and are not normally found indoors,” said Sutherland. “Outdoors, if you have an irrigation control box, leaky hosebib or water meter box, or a French drain system, that's where you'll find them. But if this water supply has been reduced or shut off, this population you didn't even know of – that may have existed for years – may crawl under doors or into foundation cracks and move indoors in search of water.”

Jim Farrar has been named director of the Statewide Integrated Pest Management Program for the University of California's Division of Agriculture and Natural Resources. He will begin the new position on Oct. 1.
UC IPM works with growers and residents to protect human health and the environment by reducing risks caused by pests and pest management practices.
Farrar is currently director of the Western IPM Center, where he has served since 2013. He succeeds Kassim Al-Khatib, UC IPM director since 2009, who is transitioning to a UC Cooperative Extension specialist position located in the Department of Plant Sciences at UC Davis. There Al-Khatib will focus on his research in weed management.
“UC IPM is a widely recognized national leader in integrated pest management,” Farrar said. “I am excited to continue efforts to make IPM the standard practice for managing pests in agriculture, communities and natural areas in California.”
Prior to joining the Western IPM Center, Farrar was a professor of plant pathology in the Department of Plant Science at California State University, Fresno for 12 years.
At Fresno State, Farrar received three teaching awards. He taught courses in plant pathology, plant nematology, diagnosis and control of plant diseases, crop improvement, aspects of crop productivity, mycology, sustainable agriculture and advanced pest management. His research centered on fungal diseases of vegetable crops, including management strategies for cavity spot of carrot. During his Fresno State tenure, he served four years as chair of the Department of Plant Science and a year as interim chair of the Department of Food Science and Nutrition.
From 1995 to 1997, Farrar taught in the Botany Department at Weber State University in Ogden, Utah. At Weber State, he conducted research on rock cress plants infected with a rust fungus that causes false-flowers. This rust is closely related to a species that is a potential biological control agent for dyer's woad (Isatis tinctoris), an invasive weed.
Farrar has published scientific papers, extension newsletter articles, and articles in agricultural industry magazines. He also wrote a chapter in the book Tomato Health Management and five disease descriptions in the book Compendium of Umbelliferous Crop Diseases. He recently completed a three-year term as senior editor for feature articles in the journal Plant Disease and was senior editor for the online journal Plant Health Progress for three years. Farrar is a member of the American Phytopathological Society and the Pacific Division of the American Phytopathological Society.
The Wisconsin native completed his Ph.D. in botany and B.S. in plant pathology at the University of Wisconsin, Madison, and his M.S. in plant pathology at UC Davis.

An article in the current issue of California Agriculture, the peer-reviewed journal from the University of California Agriculture and Natural Resources, examines the spread of herbicide-resistant weeds in California and shows how UC researchers and Cooperative Extension specialists are helping growers to understand and manage the factors that drive it.
Five more articles in this special issue of California Agriculture highlight the work of UC Agriculture and Natural Resources on pests and diseases that threaten the state's people, agriculture and natural resources. The commitments to research and outreach profiled in the issue include the Endemic and Invasive Pests Strategic Initiative, the UC Statewide IPM Program and several successful collaborations with regulatory agencies and the agricultural community.
Whether it's pinkeye, bluetongue or poisonous plants, UC maintains a strong network of laboratories and field experts to protect livestock health in California.
Regional alliances of federal, state and university plant diagnostic labs work together to identify and control disease spread.
Managing newly established pests
A regulatory program coordinated by government agencies, scientists and growers successfully contained an infestation that threatened California vineyards.
The 1999 arrival in California of a new Pierce's disease vector, the glassy-winged sharpshooter, posed a major new threat to California vineyards and orchards. A 15-year collaborative effort has successfully contained the sharpshooter and led to major improvements in our understanding of the biology of Pierce's disease, including promising advances in the development of disease-resistant grapevine lines.
Maintaining long-term management
Little or no crop rotation and limited herbicide options have contributed to the rise of herbicide-resistant weeds in orchards, vineyards and rice fields.
The UC Integrated Pest Management Program helps provide management solutions for invasive pests that destabilize IPM programs in agricultural and urban landscapes.
E-edition research article
The spread of the invasive insect in the late 1990s led to increased costs and changes in agricultural practices for grape, citrus and nursery producers.

The agricultural pest, native to southeast Asia and now found in many parts of North America, was first observed in California in the fall of 2008 in the central valley, but was not identified until early 2009. It is reported to attack soft-skinned, ripening fruits, and has been a particular problem for raspberry and cherry growers in California.
The research team – composed of Phaff Yeast Culture Collection curator Kyria Boundy-Mills of the UC Davis Department of Food Science and Technology; Frank Zalom UC Cooperative Extension specialist in the Department of Entomology at UC Davis and integrated pest management expert; doctoral student Kelly Hamby in the Zalom lab; and UC Davis visiting professor Alejandro Hernandez of University of Extremadura, Spain – published their work in a recent cover article of the journal Applied and Environmental Microbiology, the No. 1 cited journal in microbiology.
"This represents the first look at potential yeast associations of Drosophila suzukii," said Hamby.
“Often Drosophila have interactions with yeast communities, and communities often vary between host plant species, so it was a bit of a surprising that we found Hanseniaspora uvarum so often, though, we used only culture-based methods so other yeasts may be present that are hard to culture,” Hamby said.
Hannah Burrack, a former Zalom lab graduate student (now an assistant professor and Cooperative Extension specialist in the Department of Entomology, North Carolina State University) originally found that olive flies were more attracted to yeasts that were isolated from the flies themselves than to the Torula yeast bait that is commercially available for olive fruit fly management, Hamby said.
In their journal article, the authors wrote that “D. suzukii is unique in that it oviposits on marketable fruit relative to overripe or damaged fruit, and its injury facilitates colonization by other Drosophila species. If untreated, it is capable of causing a potential $860 million of revenue loss annually to blackberries, raspberries, and cherries in California, Oregon, and Washington. Knowledge of potential yeast associations could be used in lure development.”
Zalom said the pest is a major problem in the area for backyard cherries. “Many residents have not been able to harvest cherries for several years now.”
