The University of Hawaii Pollinator Ecology Lab


Dr. Chrissy Mogren received her PhD in Entomology from the University of California, Riverside in 2013. Her dissertation was titled "Outcomes of chronic arsenic exposure in aquatic insects." This novel interdisciplinary study melded the fields of environmental toxicology, insect physiology, insect behavior, and stream ecology. Her first postdoctoral position applied many of these scientific disciplines in a different entomological system: pollinators in heavily monocultured agricultural environments. From 2013-2015 she performed research on the effects of plant-incorporated pesticides in corn (neonicotinoids and RNAi) on honey bees, as well as risk mitigation for honey bees and native bees using conservation strips at the USDA North Central Agricultural Research Laboratory in Brookings, South Dakota. From 2015-2017 she expanded upon the physiological aspects of this research in a second postdoctoral position at the Louisiana State University AgCenter in Baton Rouge, Louisiana in collaboration with scientists at the USDA Honey Bee Breeding, Genetics, and Physiology Laboratory. Since December 2017, she has been an Assistant Specialist at the University of Hawaii at Mānoa in the Department of Plant and Environmental Protection Sciences, with a research and extension emphasis on honey bee health and pollination ecology in Hawaii.

IMG-4835Daniel Hausler is pursuing his M.S. in Entomology with his these is titled "Dietary effects of Prosopis pallida (common kiawe) pollen on Apis mellifera (European honey bee) health and colony strength in Hawaii." Specifically, his research will identify the pollen collected by honey bees in environments dominated by kiawe trees on Oahu and Maui, quantify the macronutrients of bee-collected pollen to evaluate how they change through time, and assess how pollen diversity impacts individual bee and colony health. 



Haley Zielomski assisted with Dr. Mogren's ongoing research on which native and introduced plant species are preferred forage plants for honey bees on Kauai by processing samples during the spring and summer of 2020.





UH students Caitlin Wright and Eve Berlinsky assisted with Dr. Mogren's ongoing research on which native and introduced plant species are preferred forage plants for honey bees on Kauai. They processed pollen samples, helped with methods development, and assisted with laboratory analysis of total protein and lipids during the summer of 2019. 




Keilyn at Ka Iwi shoreline collecting dataKeilyn Ing, a Hawaii native who graduated from Santa Clara University in 2019, completed a directed research project on Hawaiian yellow-faced bees during the summer of 2018. She was interested in learning about how an endangered species, Hylaeus anthracinus, was impacted by potential competition with honey bees along its coastal habitat at the Ka Iwi State Scenic Shoreline on Oahu. She designed the experiments, collected data in the field, analyzed the data, and contributed to writing the final manuscript.
