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.”

DAVIS — Integrated pest management (IPM) specialist Frank Zalom, professor and former vice chair of the UC Davis Department of Entomology and soon-to-be president of the 6000-member Entomological Society of America, is one of three Americans invited to speak at an international IPM workshop, Oct. 16-19, in Berlin, Germany.
Zalom, invited by the Federal Ministry of Food, Agriculture and Consumer Protection of Germany, will speak on “Stimulating Use of Professional IPM Consultants in Agriculture, Benefits for Farmers and Society,” on Monday, Oct. 17.
The event is sponsored by the Organization for Economic Co-Operation and Development (OECD), which helps governments of the developed countries tackle the economic, social and governance challenges of a globalized economy. The OECD is celebrating its 50th anniversary this year.
At the OECD workshop, to be held in the Julius Kuhn Institute, Federal Research Center for Cultivated Plants, invitees will develop recommendations related to the workshop themes, adoption and implementation of IPM in agriculture, contributing to the sustainable use of pesticides and to pesticide-risk reduction.
Wolfgang Zornback, chair of the OECD Working Group on Pesticides, German Federal Ministry of Food, Agriculture and Consumer Protection, will welcome the group.
The speakers will include noted IPM specialists from Australia, Denmark, Canada, Germany, Japan, Korea, New Zealand, The Netherlands and the UK. About 100 participants were either nominated by their governments or invited by the OECD. Half of the participants will include government representatives working on pesticide regulation, and half of the participants will include representatives from international/regional organizations: European Commission, Food and Agriculture Organization (FAO), European and Mediterranean Plant Protection Organization (EPPO), International Organization for Biological Control (IOBC), bio-pesticide industries, environmental and consumer organizations and academia.
Americans joining Zalom in Berlin will be Tom Green of the US/IPM Institute of North America in Madison, Wis., who will discuss “IPM in U.S. Schools: Challenges, Opportunities and Implications for IPM in Agriculture” and James VanKirk of the Southern Region IPM Center, North Carolina State University, who will address “IPM Pest Information Platform for Extension and Education.”
The OECD workshop will conclude with a visit to the German chancellery.
Zalom will begin a four-year commitment to the Entomological Society of America (ESA) this fall when he will be inducted as vice president-elect at the organization’s 59th annual meeting set Nov. 13-16 in Reno. He will subsequently move up to vice president and president and then serve a year fulfilling the duties of past president. The UC Davis entomologist will become president at the end of the 2013 annual meeting and then will serve as president at the 2014 meeting in Portland, Ore.
Zalom has been heavily involved in research and leadership in integrated pest management (IPM) activities at the state, national and international levels. He directed the UC Statewide IPM Program for 16 years (1986 -2001) and is currently experiment station co-chair of the Association of Public and Land-Grant Universities (APLU) National IPM Committee.
Zalom focuses his research on California specialty crops, including tree crops (almonds, olives, prunes, peaches), small fruits (grapes, strawberries, caneberries), and fruiting vegetables (tomatoes), as well as international IPM programs.
The IPM strategies and tactics Zalom has developed include monitoring procedures, thresholds, pest development and population models, biological controls and use of less toxic pesticides, which have become standard in practice and part of the UC IPM Guidelines for these crops.
In his three decades with the UC Davis Department of Entomology, Zalom has published almost 300 refereed journal articles and book chapters, and 340 technical and extension articles. The articles span a wide range of topics related to IPM, including invasive species management, biological control, insect population dynamics, pesticide runoff mitigation, impacts and management of newer, soft insecticides, development of economic thresholds and sampling methods, and determination of insect host feeding and oviposition preferences.
The Zalom lab has responded to six important pest invasions in the last decade, with research projects on glassy-winged sharpshooter, olive fruit fly, a new biotype of greenhouse whitefly, invasive saltcedar, light brown apple moth, and the spotted wing Drosophila.
Zalom is a fellow of ESA, American Association for the Advancement of Science, and the California Academy of Sciences.
Highly honored for his work, Zalom received the Entomological Foundation’s 2010 “Award for Excellence in IPM,” an award sponsored by Syngenta Crop Protection and given for “the most outstanding contributions to IPM.” In 2008 he was part of a team receiving an International IPM “Excellence Award” at the sixth International IPM Symposium. Also in 2008, Zalom was part of the seven-member UC Almond Pest Management Alliance IPM Team that received the Entomological Foundation’s "Award for Excellence in IPM.” The Pacific Branch of the ESA awarded Zalom its greatest honor, the C. W. Woodworth Award, in 2011.
