Jonathan  Koch    Research Entomologist Phone: (435) 797-7151 Fax: (435) 797-0461 Office Location: BNR173 UTAH STATE UNIVERSITYNATURAL RES BIOLOGY BLDGLOGAN, UT 843225310 **/ARSUserFiles/55207/KochJonathan_Headshot.jpg**  **Research Program** Bumble bees are significant pollinators of agricultural crops, including greenhouse tomatoes, a crop worth $690 million annually to the USA, Canada, and Mexico. Despite their importance to agriculture, disturbing reports of bumble bee population collapse have been observed in the United States, fueling environmental and economic fears of population decline. To address these significant concerns Dr. Koch leads a research program at the USDA-ARS-PWA-Pollinating Insect Research Unit that aims to deliver cutting-edge, scientific tools and innovative solutions that promote bumble bee sustainability and availability to farmers, producers, and industry. To meet this vision, his group conducts research that 1) investigates the extent and causes of bee population decline, 2) improves the management of wild and commercial bumble bee species, 3) understands bee biology as related to management goals, and 4) evaluates the genetics of bee species of commercial and ecological interest with the goal of conserving genetic diversity. **Research Status** Dr. Jonathan Berenguer Uhuad Koch is a Research Entomologist who brings more than 15 years of research experience in entomology, population genetics, and biodiversity conservation to the USDA-ARS. Dr. Koch has authored a diversity of peer-reviewed journal articles, a field guide to the bumble bees of the western USA (144 pages), led the digitization effort of one database product, USBombus, and co-developed a historic bumble bee specimen database product. Dr. Koch has participated in systematic nationwide surveys of bumble bee pollinators, culminating in the collection of 11,447 specimens across 304 locations in the western United States, including Alaska. Dr. Koch has identified 40,882 bumble bee specimens to species which are digitized into the U.S. National Pollinating Insect Collection. Currently, Dr. Koch is co-leading efforts to sequence the genomes of multiple species of bumble bees and yellow-faced bees, including two species protected under the U.S. Endangered Species Act: the rusty patched bumble bee, Bombus affinis, and the Anthricinan yellow-faced bee, Hylaeus anthracinus. The results of the different sequencing projects will provide scientific resources to make effective management decisions in both agricultural and non-agricultural systems. Dr. Koch received his B.A. (Geography) and B.S. (Environmental Science) from the University of Hawaii, Hilo and his M.S. (Biology) and Ph.D. (Ecology) from Utah State University. Following his Ph.D., Dr. Koch successfully obtained three postdoctoral fellowships from the National Science Foundation, David H. Smith Conservation Research Fellowship Program, and the USDA-ARS. At the USDA-ARS, Dr. Koch’s research has been funded by USDA-NIFA, NSF, Project Apis M, Alfalfa Pollinator Research Initiative, and the USFWS.  **Projects**Sustainable Crop Production and Wildland Preservation through the Management, Systematics, and Conservation of a Diversity of Bees
