Meet Dr. Meghan Vankosky

Dr. Meghan Vankosky started her position as a research scientist with Agriculture and Agri-Food Canada at the Saskatoon Research and Development Centre on July 18, 2016. Most recently, Meghan worked as a postdoctoral scholar at the University of California, Riverside. Her work there focused on establishing a release program for a parasitoid used for biological control of the Asian citrus psyllid in southern California, and on studying the competitive interactions of that parasitoid with another primary parasitoid of the pest. In the past, Meghan studied the behavior and life history of an omnivore used for biological control at the University of Windsor in Ontario (Ph.D., 2010-2015), and integrated pest management strategies and biological control of the pea leaf weevil at the University of Alberta (M.Sc., 2008-2010).  

As a field crop entomologist with AAFC, Meghan hopes to develop a strong IPM-based research program that focuses on understanding insect pests and developing sustainable management programs that will benefit both producers and the environment. She currently plans to investigate the impact of the pea leaf weevil and assess management options for this pest in Saskatchewan. She will also be involved with a project studying the life history and impact of the swede midge in canola crops in the Prairies.

Meet Dr. Boyd Mori

Dr. Boyd Mori – (Research Scientist – Entomology) Boyd completed his PhD in 2014 at the University of Alberta on pheromone monitoring and management of the red clover casebearer (Coleophora deauratella) moth in the Peace River region of Alberta. He then undertook a Postdoctoral Fellowship at the Swedish University of Agricultural Sciences (Alnarp, Sweden) where he researched the chemical ecology of the highly invasive spotted wing fruit fly (Drosophila suzukii) with a focus on alternative pest management strategies. Boyd joined AAFC-Saskatoon in April 2016.

Boyd’s primary project will be on the ecology of swede midge-host plant interactions, where he aims to identify host plant resistance mechanisms against the swede midge, a potentially significant pest of canola. He is a strong proponent of integrated pest management and has a robust background in insect behaviour and physiology which he uses to develop monitoring and management tools for insect pests.

As of March 2020, Dr. Mori took an Assistant Professor position with the University of Alberta. He can be reached at

Meet Dr. Tyler Wist

Dr. Tyler Wist spent his early insect years killing mosquitoes before studying pollinators in Echinacea crops for his M.Sc. with Dr. Art Davis at the University of Saskatchewan. A Ph.D. from the University of Alberta with Dr. Maya Evenden taught him the unseen world of insect chemical ecology, and invasion dynamics and the parasitoid complex of a recently introduced lepidopteran pest, the ash leaf coneroller. Drs. Chrystel Olivier and Owen Olfert brought him in on an NSERC Visiting Fellowship on the cereal aphid project and then had him chasing leafhoppers in cereal and canola crops.  Tyler is the current President of the Entomological Society of Saskatchewan and has begun a research scientist position at Agriculture and Agri-Food Canada’s Research and Development Centre in Saskatoon as a Field Crop Entomologist on January 25th 2016.

Tyler is working on developing a dynamic action threshold for cereal aphids that incorporates the predatory pressure of natural enemies, determining the economic threshold and effect of landscapes on flea beetles in newer, hybrid canola varieties, and tracking aster leafhopper populations and aster yellows infection in canola and cereal crops.  He is also investigating new integrated pest management tools for wheat midge and chasing Lygus bugs in canola and aphids in pulse crops.

Tyler can be reached at or 306.385.9379.

Meet Dr. Haley Catton

Dr. Haley Catton joined AAFC-Lethbridge as a Research Scientist in Cereal Crop Entomology in April 2016. With a diverse background in studying trees, weeds, native plants, insects, and mammals, Haley specializes in population biology, insect-plant interactions, biological control, field experimentation and analysis of large data sets. Originally from Winnipeg, Haley earned a B.Sc. (Agriculture) and M.Sc. (Plant Science) from the University of Manitoba, a Ph.D. (Insect-Plant Interactions) from the University of British Columbia Okanagan, and conducted postdoctoral research at the University of Lethbridge. Her research program at AAFC will draw from all of these experiences to focus on pest and beneficial insects in cereal crops on the prairies. Her target pests range from established problems like wheat stem sawfly and wireworm to emerging pests such as the invasive cereal leaf beetle.

Haley wants to connect with producers and hear about your priorities for research. Follow her on Twitter at @haleycatton or reach her at or 403.317.3404. Fair warning: Haley is a diehard Blue Bombers fan… Saskatchewan Roughriders fans beware.
