Rebecca Hallett is the Interim Associate Vice President Research of the Agri-Food Partnership in the Office of Research at the University of Guelph (U of G). She holds a bachelor’s in biogeography from the University of Toronto, as well as a master’s in pest management and a PhD in entomology from Simon Fraser University (SFU). Following her PhD, she spent two years working as a postdoctoral researcher with Agriculture and Agri-Food Canada in Saskatoon. She lives in Guelph with her husband and has two adult children.

What was your previous role at the U of G?

I’ve been a professor in the School of Environmental Sciences since 1998. Before my current role, I was Associate Dean of Research and Graduate Studies for the Ontario Agricultural College, which includes six departments that focus on food, agriculture, communities and the environment.

What got you interested in entomology?

I must give some credit to my dad. He has always been very devoted and academic about his hobbies. When I was a tween, he began collecting insects. I went into botany because I always loved plants, but the insect connection was there.

When I got to SFU, there were exciting things happening in entomology and fewer opportunities in integrated pest management on the botanical side. I had done some travelling and volunteering in India and thought I might get into international agricultural development work. When I couldn’t use this experience as part of my master’s, I connected with a Canadian entomologist working on a development project in Indonesia. I went to work with him and my move into entomology happened. I knew I wanted to be a scientist from a young age, but I really wanted to do something that was going to solve problems. So, agriculture and entomology were ways for me to do that.

Tell us a bit about what you’re working on at U of G.

My current position oversees the university side of the Ontario Agri-Food Innovation Alliance, a collaboration between the Ontario Ministry of Agriculture, Food and Agribusiness (OMAFA); U of G; and Agricultural Research and Innovation Ontario, whose research stations we operate as part of our research activities.

My training was in chemical ecology using insect pheromones and host plant compounds to manipulate insect behavior for pest management, which has been a theme throughout my work. I work closely with OMAFA, various crop specialists and the provincial entomologists to look at invasive or emerging pest issues that affect Ontario agriculture.

I also collaborate with Jocelyn Smith on the “Mitigation and management of Cry1F resistance in European corn borer in Canada” project, of which Manitoba Crop Alliance is a funding partner. Jocelyn is the scientific lead and we co-advise graduate students.

Two aspects I’ve been most closely involved in are work by master’s students Emily Glasgow and Jenna Straughan. Emily looked at potential links between pheromone races and BT susceptibility, and the heritability and fitness implications of the field-evolved Cry1F resistance trait. Emily graduated a couple of years ago and we’re now co-advising Jenna on related work. Her focus is the phenology of European corn borer and its occurrence in Ontario, number of generations and use of degree-day modelling to predict adult flights. She’s also done work on isotope detection and the relationship between pheromone races and host plant types, testing whether they are as separated on distinct host plants as the literature indicates.

This work is key to understanding the pest’s life history and timing of occurrence, and has implications for integrated resistance management strategies.

What can you say about the value of farmers providing funding and support to your organization?

Support from farmers is extremely important, as they tell us what they need and what challenges they are facing. Today, so much research funding is reliant on leveraging funds provided by industry. I’ve only seen that trend increase through my career as a faculty member. Many of our funding programs are dependent upon showing that what we are doing is important to industry or to the agricultural sector. So, the funding provided by producer organizations is critical to making research – and solutions to the challenges growers are facing – happen.

How does that farmer funding and support directly benefit farmers?

Ideally, through these research projects we can return results to growers. We aim to get that research into practice to help to inform their management practices and decision-making.

Some of the most rewarding things I’ve done have been those that have resulted in changes and improvements for growers in terms of pest management and decision-making. We did one of the first insect-based apps, Aphid Advisor, for example. It considered the natural enemies (mainly lady beetles) that were being seen on soybean plants at the same times as aphids to adjust the decision as to whether an insecticide spray would be needed. In the end, we were able to deliver a service that they could use to improve their decision-making. This is one example of a research idea coming from growers – they saw the lady beetles in their soybean fields and wanted to know what contribution they were making to combatting the soybean aphid.

How do you spend your time outside of work?

My husband and I really enjoy travel. We spend a lot of time talking about where we might go next and what we might do there. We have a little “pandemic trailer” we bought to do some camping and we plan to do the west coast of Newfoundland this summer.

What gets you most excited about your work?

Trying to make a difference. In all the roles I hold as a professor and administrator I try to lead from a place of caring and I want to help solve problems. That motivates me.

Any favourite travel experiences you’d like to share?

I absolutely love Southeast Asia: the people, the food, the climate and the biodiversity is incredible. I learned to scuba dive last year. We went to Raja Ampat in eastern Indonesia, which is one of the most biodiverse marine environments in the world, and it was great. If you’ve been to the Caribbean, there are about 57 species of coral there. Raja Ampat is part of the Coral Triangle and there are over 600 coral species, so all the little ecological niches for all these different organisms to occupy is amazing. We saw such incredible things, from nearly microscopic creatures almost too hard to see to ocean manta rays with 15-foot wingspans floating over top of us. It was just mind blowing.
