About me

As a Vegetable Extension Specialist (65%) and Applied Insect Ecologist (35%) in the Department of Entomology at the University of Wisconsin, Madison, my responsibilities include the development, implementation, and delivery of a research-based, extension program to support integrated pest management of insect and mite pests affecting fresh-market and processing vegetable production in Wisconsin.

My extension and research program is centered on the ecology and management of insects of commercial and fresh market vegetable crops. To meet current and emerging challenges, novel research approaches are formulated in response to the stated needs of Wisconsin vegetable growers and producers, cooperating statewide and regional Extension Specialists, County Extension Agricultural Agents, pest management practitioners, crop consultants, and other agribusiness stakeholders in order to assess immediate and developing pest problems. Next, my research program tests hypotheses that further the understanding of pest population biology based on sound ecological principles derived from a combination of both field and laboratory research. Here, it is essential to balance the development of short-term solutions to these immediate and emerging problems, which out of necessity may require purely empirical and at times ad-hoc approaches, with research to develop fundamental concepts and knowledge that will lead to the development of long-term sustainable solutions. Solutions and strategies developed for the commercial and fresh-market vegetable industry must be durable, economical and both environmentally and socially acceptable to remain effective against key, vegetable pest species affecting the industry.

As an extension educator, it is my goal to create an environment conducive to learning and information exchange where vegetable industry stakeholders can be motivated to acquire new information, concepts and skills. A successful extension and research program is most often the result of a team of collaborators working together. My extension and applied research-based program collaborates with research and extension faculty within the departments of Entomology, Horticulture, Plant Pathology, and Crop Science at the University of Wisconsin as well as scientists from other institutions.

Ben Bradford

bbradford@wisc.edu

Ben completed his M.S. degree in the Groves Lab and is continuing on in the lab working on a variety of projects, including the upkeep of this website.  During his time as a graduate student, he explored the problem of groundwater contamination by neonicotinoid insecticides, specifically thiamethoxam, by surveying high-capacity irrigation wells in the Central Sands vegetable growing region of Wisconsin.   In addition to describing the spatial extent and magnitude of this contamination, his thesis explored of the relationship between neonicotinoid contamination and landscape composition in the vicinity of sampled wells. Prior to moving to Wisconsin to pursue a degree in Entomology, Ben worked with the USDA-ARS Aquatic and Invasive Weeds Research Unit in Davis and Albany, CA.

Victoria Lason

lason@wisc.edu

Victoria is a M.S. entomology student co-advised by Dr. Jeri Barak and Dr. Russell Groves. Her current research concerns the characterization and influencing factors responsible for the survival and spread of Salmonella enterica in fresh produce crops, primarily through an entomological perspective. Analyzing the relationships between Salmonella persistence in fresh produce and a variety of phytophagous insects holds potential to aid in the development of food protection strategies in the future.

Erin Lowe

eblowe@wisc.edu

Broadly, I am interested in applying ecological and interdisciplinary research to further the sustainability of agricultural systems. I am particularly interested in pollination ecology, specifically understanding how local management and landscape features interact to influence wild pollinators and how pollinator behavior impacts the delivery of pollination services. My thesis project focuses on the ways in which pollinator plantings and habitat availability impact the richness, abundance, and nesting success of wild bees in pickling cucumber.

Lab alumni

Ben Sanchez-Sedillo

sanchezsedil@wisc.edu

Benjamin was a M.S. student in the molecular and environmental toxicology program.  His work focused on studying the adverse effects of pesticides on aquatic insects in Wisconsin tributaries.  Ben tested these tributaries for the neonicotinoid insecticides Imidacloprid and Thiamethoxam.  He enjoys outdoor activities like fishing, hiking, and snowboarding.

BowerRyan Bower

rbower@wisc.edu

Ryan was a PhD student co-advised by Dr. Russell Groves and Dr. Jeri Barak. He took a genetic approach to discover colonization factors within the Salmonella enterica genome while in phytophagous insects and plants. Ryan’s objective was to further our basic understanding of how Salmonella spp. can persist in such a wide diversity of organisms and help to direct future protection strategies. Securing a safe food supply will be critical as food is in higher demand in the coming years.

kat-prince-smKathryn Prince

Kat Prince completed her M.S. in entomology and agroecology in this lab.  Her research took place in Wisconsin’s Central Sands growing region, where she studied the wild pollinator community in conventional vegetable crops.  She also analyzed the concentration of neonicotinoid pesticides within plant tissues as these crops grow.  The results from this project should help us learn which bees are present in this important agricultural region and the environmental risks they may be facing. Kat recently left the lab to start a job at the NRCS Field Office in Fresno, CA.

natalie_smNatalie Hernandez

Natalie’s research focused on correlating which species of aphid are present in potato fields when potato virus Y (PVY) is first detected.  By determining which species are actually spreading the virus, PVY management practices can be improved.
