Principle Investigator

Vera Krischik

Extension Specialist in Nursery, Greenhouse, and Landscape IPM
Department of Entomology, University of Minnesota

Vera Krischik is a University of Minnesota Associate Professor and IPM specialist with 35 years of experience promoting Integrated Pest Management (IPM), biocontrol, and compatible insecticides to protect pollinators and other good bugs in greenhouses, nurseries, lawns, urban forests, parks, and restorations. Our lab's research identifies the best ways to manage pests through IPM to reduce non-target effects on native pollinators and biocontrol insects, such as parasitoids, lady beetles, native butterflies, and native bees, such as rusty patched bumblebee, Bombus affinis, and blue orchard bee, Osmia lignaria. Data from our site specific IPM and biocontrol program is promoted by sharing our expertise at national, state, and local research and outreach meetings. Our lab was requested to be on a technical committee to help the Minneapolis Park & Recreation Board develop IPM programs for their parks. We are members of two national committees on IPM for landscapes, two national committees on monarch and rusty patched bumblebee, USDA grant panels that review proposals associated with pollinators, and local efforts by businesses and municipalities to develop IPM programs. Every year we train pesticide applicators on how to correctly use pesticides in nine MDA, MNLA, UM workshops. We provide over 20 talks yearly to growers, commodity groups, and citizens on IPM and pollinators. We have an online training course on IPM and pesticides with the green industry group MNLA. We maintain IPM for Landscape, Nursery, and Greenhouse, an IPM website with technical information about pesticides and pollinators and features an online 300 page IPM manual to identify pests and develop appropriate IPM programs. In addition, we have created IPM and Pollinator Conservation, a website devoted to IPM of pollinators, with information on pollinator identification, proper host plants, and IPM management of restorations. From 2000 to 2014 the Krischik Lab taught 2 courses on IPM and pesticides that were required for the UM Horticulture Major and were canceled when the Horticulture major was canceled in 2014; ENT4015-IPM of ornamentals and turf and HORT 5009-Pesticides.

Current Staff

Dr. Garima Gupta

Post-doctoral Researcher
Department of Entomology, University of Minnesota

Dr. Garima Gupta is a Post Doctoral Researcher who has worked in the Krischik Lab previously and recently rejoined the lab in February of 2025. Dr. Gupta has over 15 years of experience in research, teaching, and academic leadership. She holds a Ph.D. in Agricultural Entomology (2005) with a minor in Plant Pathology and an M.Sc. in Entomology (2002) from GBPUAT Pantnagar, India. She is currently working as a Postdoctoral Associate and Visiting Scientist in the Krishik Lab. Earlier, she served as Professor and Head of the Department of Agriculture at Chandigarh University (2023–2025), and as an Associate Professor from 2019 to 2023. During this time, she played an important role in both academic and administrative development.

In her leadership roles, she worked as Head of the Department, Research Coordinator, and as an active member of various academic committees. Dr. Gupta has led two important research projects as Principal Investigator. One was funded by the Department of Science and Technology, India-WOS-A Scheme, which focused on using helpful insects to control Tetranychus urticae (a harmful mite) in greenhouses. The second project was supported by Council of Scientific and Industrial Research (CSIR) and studied the use of microbial insecticides along with chemical insecticides in a safe and balanced way.

Her research mainly focuses on using natural and environment-friendly methods like biological, botanical, and microbial control to manage harmful insects. These efforts have helped in promoting safer and more sustainable farming practices. Her work has been recognized through several research publications that highlight the success and impact of her scientific contributions.

Kieran Timmins

My name is Kieran Timmins. I am a junior in Environmental Science, Policy, and Management. I love to learn new things, and I am especially interested in topics such as ecology, sustainability, and their connections to people and policy. I am currently working on a mode of biocontrol for Japanese Beetles, and have been with the Krischik Lab since 2023. This is the first lab I have worked in and it has given me the necessary experience, and insight, to understand what my future career might look like.

Sophia Stone

My name is Sophia Stone, I am a senior in Plant Science on the Agroecology track. I joined the Krischik Lab in January 2024 and since then I have enjoyed my time here. I am passionate about sustainable food systems and conservation. I also have an interest in entomology and Integrated Pest Management (IPM) so this lab is a very valuable experience to me.
