Don’t miss it!

While driving up highway 400 for that cottage getaway in the Muskokas, you’ll pass by a little slice of Ontario agriculture on some of the darkest soil you’ve ever seen. But be careful: If you blink, you might miss this beautiful place known as the Holland Marsh. Located 50 km north of Toronto, the Holland Marsh is known for its intensive production of carrots, onions, and over 60 other horticultural crops. The Marsh contributes over 1 billion dollars to the Ontario economy through the production, processing, and shipment of vegetables.

For my MSc project, I’m looking at ways to enhance ecosystem services in the Holland Marsh. Ecosystem services are benefits humans gain from ecosystems, which can include water and air purification, carbon sequestration, agricultural pest management, and crop pollination. My research specifically focuses on enhancing non-crop areas so that they can provide better habitat for pollinators and natural enemies of crop pests. Studies show that the enhancement of “naturalized” non-crop areas (e.g., hedgerows, field margins, riparian areas, mowed grass) with vegetative and floral plantings can help support the abundance and diversity of beneficial insects within an intensive agricultural system. The habitat provided for these beneficial insects can offer several ecosystem services to growers, from pollination of crops to assisting with crop pest control. Until recently, the Holland Marsh had almost no non-crop habitat. In 2010 the Holland Marsh Drainage System Canal Improvement Project was initiated, and at its completion in July 2016, 19 km of canals had been relocated and dredged, and 10 km of berms (dykes) had been expanded to improve safety and efficiency. This expansion of the berms increased the amount of non-crop habitat in the Holland Marsh. My study investigates how different vegetative enhancements on the canal berms might affect beneficial insect complexes and agricultural pest populations at the Holland Marsh. I’m using both active and passive trapping to assess the abundance and diversity of natural enemies, pollinators, and insect pest populations in two different vegetative enhancements throughout the growing season.

Although vegetative enhancements can be beneficial, stakeholders were concerned about the possibility that the enhancements could provide a refuge for pests (e.g., insects, weeds, vermin) and that they may not be aesthetically pleasing. To address these concerns, I orchestrated a public and grower outreach day (Berm Day) on July 5, 2019 with help from funding by the Entomological Society of Ontario. The goal of Berm Day was to connect with the public and growers about the importance of enhancing non-crop habitat to support beneficial insects in intensive agricultural systems. I hoped to create a dialogue surrounding the importance of ecosystem services, and to disseminate some of my findings. My study has shown that vegetative enhancements support a greater abundance of natural enemies than the natural berm vegetation and increase floral resources for pollinators. The enhancements have not provided a refuge for primary insect pests of the crops grown at the Holland Marsh.

Overall, Berm Day was a great success. I connected with local growers, members of the public, master gardeners, conservation authorities, and members of the Ontario Ministry of Agriculture, Food, and Rural Affairs, over some fresh baked goods and coffee. We opened a dialogue about the project and shared ideas for future research, including management approaches and new seed mixes to improve the aesthetics appeal of the plantings. Everyone who attended left with a package of Ontario Native Seed Mix to plant at home, which was generously provided by Syngenta’s Operation Pollinator Multifunctional Landscapes.

I have heard once or twice that diversity is the spice of life, and within an intensive agricultural system, it can play an important role by offering numerous benefits for both growers and natural ecosystems. The conservation and enhancement of non-crop habitat can help provide ecosystem services in the Holland Marsh by increasing and supporting beneficial insects.

A special thanks to all the volunteers, advisors, the Muck Crops Research Station’s staff, Paul Hoekstra, and the Entomological Society of Ontario for making this day possible.

Dear Researchers in Integrated Pest Management,

The Pest Management Centre compiles the Pest Management Research Report (PMRR) for the Canadian Phytopathological Society (CPS), in conjunction with the Entomological Society of Canada. The PMRR facilitates the exchange of information on Integrated Pest Management (IPM) among persons involved in research and advisory services on IPM of insect pests and plant diseases of importance to the agri-food industry in Canada.

The PMRR is published annually as a compilation of research reports by federal and provincial government, university and industry research and advisory personnel. These reports aid the development of recommendations for insect and disease management programs throughout Canada. They report on all aspects of pest management, including cultivar and management responses, and are available to support the registration of pest control products. The PMRR is published only in electronic format. The 1995-2018 editions of the PMRR are available on the CPS website for viewing and download at http://phytopath.ca/publication/pmrr/.

Please find the invitation to submit research reports for the 2019 edition of the PMRR. Also encourage any of your colleagues who conduct research into IPM to submit research reports.

Do insects feel pain?  Many of us probably ask ourselves this question.  We swat mosquitoes, step on ants, and spray poison on cockroaches, assuming, or perhaps hoping, that they can’t – but can they?  As someone who studies the physiology behind insect behaviour, I’ve wondered about it myself. Those thoughts motivated me to examine the question from the perspective of evolution, neurobiology and robotics.

Are these crickets angry? In pain from being whipped by antennae? How would we know?

To find out whether insects feel pain, we first need to agree on what pain is.  Pain is a personal subjective experience that includes negative emotions.  Pain is different from nociception, which is the ability to respond to damaging stimuli.  All organisms have nociception.  Even bacteria can move away from harmful environments such as high pH.  But not all animals feel pain.  The question, then, is do insects have subjective experiences such as emotions and the ability to feel pain?

We’ve probably all observed insects struggling in a spider’s web or writhing after being sprayed with insecticide; they look like they might be in pain. Insects can also learn to avoid electric shocks, suggesting that they don’t like being shocked.  However, just as I was appreciating how much some insect behaviour looked like our pain behaviour, I realized that Artificial Intelligence (e.g. robots and virtual characters) can also display similar behaviours (e.g. see (https://www.youtube.com/watch?v=YxyGwH7Ku5Y). Think about how virtual characters can realistically express pain in video games such as “The Last of Us” (e.g. https://www.youtube.com/watch?v=OQWD5W3fpPM). Researchers have developed circuits allowing robots and other AI to simulate emotional states (e.g. ‘joy’, ‘anger’, ‘fear’). These circuits alter how the robot/virtual character responds to its environment (i.e. the same stimulus produces a different response depending on the AI’s ‘emotion’).    However, this does not mean that robots or virtual characters are ‘feeling’ these emotions.  AI shows us that behaviour may not be the best guide to an insect’s internal experience.

Given that behaviour seemed an unreliable guide, I then looked for neurobiological evidence that insects feel pain.  Unfortunately, the insect brain is very different from the human brain.  However, once we understand how our brains perceive pain, we may be able to search for circuits that are functionally similar in insects.  Research in humans suggests that pain perception is created by complex neural networks that link up the necessary brain areas.  These types of networks require massive bidirectional connections across multiple brain regions.  Insect brains also have interconnections across different brain areas.  However, these interconnections are often quite modest.  For example, the mushroom bodies in the insect brain are critical for learning and memory. Although the mushroom bodies contain thousands of neurons, in fruit flies, for example, they have only 21 output neurons.  In humans, our memory area, the hippocampus, has hundreds of thousands of output neurons.  The lack of output neurons in insects limits the ability of the insect brain to sew together the traits that create pain in us (e.g.  sensory information, memory, and emotion).

Finally, I considered the question from an evolutionary perspective.  How likely it is that evolution would select for insects to feel pain?  In evolution, traits evolve if the benefits of a trait outweigh its costs.  Unfortunately, nervous systems are expensive for animals.  Insects have a small, economical, nervous system.  Additional neurons dedicated to an ‘emotional’ neural circuit would be relatively expensive in terms of energetics and resources.  If it is possible to produce the same behaviour without the cost, then evolution will select for the cheaper option. Robots show that there could be cheaper ways.

The subjective experience of pain is unlikely to be an all-or-none phenomenon.  Asking whether insects feel pain forces us to consider what we would accept as a subjective experience of pain.  What if it was devoid of emotional content?  What if cognition is not involved?  If insects have any type of subjective experience of pain, it is likely to be something that will be very different from our pain experience.  It is likely to lack key features such as ‘distress’, ‘sadness’, and other states that require the synthesis of emotion, memory and cognition. In other words, insects are unlikely to feel pain as we understand it.   So – should we still swat mosquitoes?    Probably, but a case can be made that all animals deserve our respect, regardless of their ability to feel pain.

There’s been a buzz in the air about bees lately, and for good reason: bees are major pollinators of both wild plants and agricultural crops, and some species are declining because of threats like habitat loss, climate change, and agricultural intensification. Many people assume the honey bee is the top pollinator among bees. But bumble bees, the honey bee’s bigger, hairier, and louder cousins, are just as important for pollination*. (For some plants, bumble bees are even better pollinators than honey bees.) North America is home to 46 bumble bee species that collectively visit hundreds of types of plants. Also, a few bumble bee species are commercially reared and sold to growers to pollinate certain crops, like blueberries and greenhouse tomatoes. Unfortunately, some bumble bee species are declining or endangered, and the status of many other species is unknown. Bumble bees are historically understudied, and so for some areas, there aren’t many bumble bee records (documented sightings of individual bumble bees with associated reference information, like sighting location, date, and species name). Without good records, it’s difficult to know how many individuals of certain bumble bee species there are now and how large their geographic range is, and how their population sizes and ranges may have changed over time. Brett Forsyth, a photographer and naturalist from Guelph, hopes to help address this problem and raise awareness about bumble bees with his new online project, Photographing Bumble Bees for Identification.

Originally from British Columbia, Brett became interested in bumble bee conservation when he moved to Ontario. Currently, there are three bumble bees on the Species at Risk in Ontario list: the rusty-patched bumble bee (Bombus affinis, endangered), the gypsy cuckoo bumble bee (Bombus bohemicus, endangered), and the yellow-banded bumble bee (Bombus terricola, special concern). Brett decided to figure out how to photograph these at-risk species, and in the process, he discovered that there are relatively poor records of many Ontario bumble bees, especially in the northern and central areas of the province.

Brett saw a way to improve our knowledge of Ontario bumble bees** via iNaturalist, an existing online citizen science project aimed at documenting and sharing observations of global biodiversity. Users create free profiles and upload photos of their biodiversity finds, where they can then be viewed by other users and identified by experts. iNaturalist educates people about the natural world, but it also can provide scientists with valuable data that can be used to track changes to species’ geographic distributions and population sizes. For those data to be useful, the species in the uploaded photos must be identifiable, which requires high-quality images that contain key body structures needed to identify the organism. But as anyone who’s ever tried will tell you, getting a bumble bee to sit still for a picture is tricky. As a photographer, Brett saw an obvious solution to that problem: simply teach people to take good pictures of bumble bees with their mobile devices, and in turn, get better data on Ontario bumble bees.

Pocket guide to photographing bumble bees by Brett Forsyth.

In a series of videos on the Photographing Bumble Bees website, Brett takes viewers step-by-step through the process of taking pictures of bumble bees and uploading their photos to the Bumble Bees of Ontario project on iNaturalist. He also provides a free, printable pocket guide that outlines the most important tips for photographing bumble bees and gives descriptions of the three at-risk species in Ontario. Brett has four general tips for getting great pictures of bumble bees. First, get as close as you can to the bumble bee. (Don’t be scared of that stinger–bumble bees really aren’t very aggressive!) Second, get separate shots of the bumble bee’s back, side, and face. These areas contain features that are important for identifying bumble bees. Third, slow motion video can be used to get good images of fast-moving insects because it produces a bunch of still images that you can sort through later to find the perfect shot. And fourth, find an app that will allow you to manually focus your phone’s camera.

Brett hopes his project will inspire 250 people to join the Bumble Bees of Ontario project on iNaturalist and generate at least 1,000 new bumble bee records from central and northern Ontario. More generally, he wants to get more people interested in bumble bees and the underappreciated world of insects. So help scientists help bumble bees: Grab your phone, get outside, and start snapping photos.

 

*This article is focused on bumble bees, but there are many other types of bees. In fact, there are around 4000 species of bees in Canada and the US. All of those bee are also very important pollinators, and many of them may also be at risk. (We know even less about other bees than bumble bees.) So please learn about other bees too!

**Maybe you’re not in Ontario, but don’t let that stop you from using these tips to photograph bumble bees in your area. Information on any bumble bee species from anywhere is important!
