Sometimes when you’re least expecting it you can find yourself presented with the adventure of a lifetime. This recently was the case for me. My adventure took me to the United Kingdom, from September 2013 to August 2016, where I completed my DPhil in Zoology at the University of Oxford.

I didn’t have any long-standing plan to attend the University of Oxford. While finishing my undergraduate degree at the Faculty of Agriculture at Dalhousie University (Truro, Nova Scotia), I decided to apply for a Rhodes scholarship on a bit of a whim. The application was daunting but nonetheless, I managed to put something together and received word that I was a regional finalist. Roughly a week before my final interview, I scanned the University of Oxford – Department of Zoology website and came across the name Owen Lewis. I read through a couple of his papers and sent him a quick e-mail explaining my situation. I received a near-immediate response. Owen enthusiastically wished me the best of luck with my interview and agreed to act as my supervisor should I receive funding. Through a combination of luck, privilege and merit I found myself presented with the opportunity to study at the University of Oxford. I submitted my application to the university a week later. Opting to spend three years being supervised by a stranger based on a single e-mail exchange is not something I would advise to others, but it is exactly what I chose to do. Fortunately, I landed in an incredibly supportive and inclusive research group – and Owen’s first exchange perfectly predicted his supervisory style: helpful, available, and incredibly kind.  

I fell in immediate love with the city of Oxford soon after my arrival. The first thing you might notice about the city is the architecture: medieval walls, ivory towers, and ancient gates seem to appear around every corner. The second thing you might notice is all the bikes – they easily outnumber the cars on the road. The squealing of rusty brakes and pinging of bells is the soundtrack of a morning commute. The third thing you might notice is the gigantic slugs and snails that appear at night – that was my experience at least.

My DPhil research explored the importance of insect biodiversity in perturbed environments using dung beetles as a model system. I did a fair amount of my fieldwork in Southwest Wales, where I was introduced to my co-supervisor Sarah Beynon. Sarah had recently completed her DPhil with Owen as a supervisor and was in the process of setting up “Dr Beynon’s Bug Farm”, which is probably best described as a mixture between a research centre, tropical insect zoo, and working farm. It also is home to Grub Kitchen, UK’s first restaurant with edible insects on the menu.  I spent my first summer living and researching on-site, while the start-up was in its initial stages. It’s a beautiful place – in the early spring the farm is blanketed with yellow iris, red campion, and various orchid species. It was a short bike ride to the coast which I frequented to enjoy steep paths, white sands, and impressive waves.

One of the things that I truly loved about the United Kingdom was the widespread appreciation and knowledge of natural history. The entomology and ecology circles that I ran in certainly would have amplified this signal, but it seemed to run deep in society-at-large. When a server interrupts your book-in-face breakfast to offer her insights about myxomatosis, a viral disease of rabbits, you might just be in the United Kingdom.

Some of my favourite memories from my time abroad were natural history outings. Richard Comont, a DPhil student in our research group took me out in the winter of 2014 to see the impressive minotaur dung beetle. We arrived at a local park in the pitch black of night, armed with a couple flashlights. Richard, who bears a certain resemblance to Hagrid (the brawny groundskeeper for Hogwarts School of Witchcraft & Wizardry), also carried a pooter, umbrella, and beating stick. We found the minotaur beetles, they were certainly impressive, but perhaps more memorable was a vivid image of a grinning Richard whaling on a bit of gorse with a broom stick, in the pitch black of the woods.

Another dung beetle memory involves Darren Mann, Head of the Life Collections at the Oxford University Museum of Natural History. Darren invited me out for a day of dung beetle recording as part of a Scarabaeoidea recording effort known charmingly as Team DUMP. We left at six in the morning, drove two-and-a-half hours to rural Wales, and sifted through animal dung on sand dunes until it was so dark that we couldn’t see our hands in front of us. Darren found one species he expected was locally extinct – upon realizing what he found, he gave a fantastic howl of excitement. I’d expect there are few people who are more enthusiastic and knowledgeable about insects than is Darren Mann. If you ever get the chance, make sure to ask him about cockroaches sometime.

A third dung beetle memory is a day I spent collecting with Sarah and her partner Andy. We were getting ready to run a few experiments, and set-up a dung beetle demonstration at a tradeshow. Of course, the powers that be sent along torrential rain. To this day, I don’t think there is a more miserable feeling than kneeling in prickly shrubs, soaked to the bone, sifting through sheep dung. Nonetheless, that’s what we did for hours and hours. Upon returning to the vehicle, I cleaned up and towelled off only to have a bird defecate directly onto my head and shoulder. There couldn’t have been a more fitting end to the day.

While my experience in Oxford was overwhelmingly positive, it did not come without its challenges. The biggest challenge I encountered was dealing with low points caused by an all-encompassing imposter syndrome. The ease and speed at which my colleagues could process and synthesize information was nothing short of intimidating.  Meanwhile, I had trouble getting my first few experiments off the ground; while simultaneously everyone around me seemed to be successfully completing ground-breaking research. I felt slow, unaccomplished, and lazy.  I tried to compensate by putting in additional time: arriving earlier, staying later, and working on weekends – but this just left me feeling burnt-out. Plenty of exercise, structuring my work days, limiting social media, and hours of conversation with my partner, friends, family, colleagues, and supervisors helped me get back on my feet.

I’ve been home in Canada since the summer of 2016, working as a post-doc and a sessional lecturer. I think often and fondly about my time spent abroad in the United Kingdom and would highly recommend it as a study destination. While competitive, there are many different funding sources that Canadian students can access, including the Commonwealth Scholarships, NSERC – Michael Smith Foreign Supplement, Rhodes Scholarships, as well as numerous other international scholarships offered at the institutional level. Living in a foreign country provides you with a fresh outlook and opens your world to a range of new experiences, ideas, and perspectives. If international study is compatible with your other commitments, mull it over a little, and think about giving it a shot – becoming an international student might be just the adventure you’ve been looking for.

Me at the University of Guelph Elora Research Station.

“It’s a story of unrequited love,” says Dr. Yolanda Chen, my Ph.D. advisor, describing our research on pheromone mating disruption. Mating disruption, a pest management strategy that involves inundating a field with synthetic sex pheromone, prevents male insects from finding their mates because they can’t cue in on individual female pheromone plumes. As a result, the males become confused and die without mating. During my time as a Ph.D. student, I’ve spent a lot of time in Vermont and Ontario becoming intimately familiar with the sex lives of swede midge, a serious invasive pest of cruciferous crops.

Swede midge (Contarinia nasturtii, Diptera: Cecidomyiidae) first arrived in North America in the 1990s in Ontario. Vegetable growers started noticing that their broccoli, cauliflower, and cabbage plants were deformed and didn’t produce heads, and that their kale leaves were twisted and scarred. On canola farms, yields decreased because of distorted plant growth. The culprit, identified by Dr. Rebecca Hallett and her research group from the University of Guelph, was a tiny fly called swede midge. The midge, only about 2 mm long as an adult, is seemingly invisible to farmers because it is so small. Within a few years, the midge had made its way from Ontario to Québec and other provinces, and into New York and Vermont.

At the University of Vermont, we are the only research lab in the US working on this pest, which is currently causing up to 100% yield loss of organic broccoli and kale in our state. Naturally, it made sense for Dr. Chen to reach out to Dr. Hallett in Guelph for collaboration to investigate management options for this pest. Together, they wrote a grant funded by the USDA to conduct pheromone mating disruption research on swede midge that would take place in both Vermont and in Guelph.

This where I enter into the story. I jumped at the opportunity to join Dr. Chen’s lab, not just because I’m interested in insect pest management, but also because of my continuing love affair with Canada. I grew up in Vermont, a small state that borders Québec and has had lots of influence from our northerly neighbors: a history of French-Canadian immigrants, widespread availability of decent quality poutine, and signage in our largest city en français, among other things. I grew up learning French and visiting nearby Montréal and later went on to study agriculture at McGill University’s Macdonald Campus. I was thrilled at the opportunity to spend more time in Canada during my Ph.D. program.

I have gotten to know the English-speaking provinces better through my graduate work as a visiting Ph.D. student in Dr. Hallett’s lab in Guelph. Although many Canadians, especially those from nearby Toronto, describe Guelph as being a “small farm town,” it felt like a real city, especially coming from Vermont. I fell in love with Guelph — the year-round farmers market, old stone buildings, beautiful gardens, and emphasis on local food. The large sprawling farms just outside the city were the perfect places for me to do my research on swede midge pheromone mating disruption, which required lots of space between plots and treatments. Back in Vermont, where the farmland is wedged in small valleys between mountain ranges, we just don’t have the scale of crop production that there is in Ontario.

Working with Dr. Hallett opened up many doors and expanded my network in Canada. Last year, my advisor and I started a collaboration with the Institut de recherche et de développement en agroenvironnement (IRDA) in St-Bruno-de-Montarville, Québec. Earlier this winter, I practiced my French and mustered up the nerve to give two extension presentations on my swede midge work to francophone farmers in Québec. I was surprised at the number of people who came up to me after my talk, appreciative that I was making an effort to communicate with them in French rather than English. They were genuinely interested in working together with my research group across the border to help strengthen our research efforts to manage swede midge.

In all the time I’ve spent in Canada (which at this point can be measured in years), I can’t think of a time when I’ve felt unwelcome. On the contrary, I am impressed with how open most Canadians are to foreigners. I hope that we can continue to work together, despite language barriers, differing political systems, and other potential challenges, to gain traction in our efforts to find solutions for swede midge and other shared invasive species in the future.

It was an early morning after a long drive from Guelph to a small fruit farm in Chatham-Kent where my undergraduate student, Caitlyn, and I were conducting a small-plot spray trial to test the effect s of repellents against Drosophila suzukii (Spotted Wing Drosophila), a recent invasive and serious fruit pest.  I knew the raspberry patch was heavily infested with D. suzukii so before getting to work, to amuse ourselves at the start of the day, I started gently shaking canes, and we watched the swarms of fruit flies disperse and hover over the fresh fruit.  However, as I went to grab a branch low to the ground, I noticed something different about one of the fruit flies sitting on a leaf.  It had characteristic white “racing stripes” along its thorax, unlike any other fruit fly I had seen.  This was it!  This was very likely Zaprionus indianus or African fig fly, another invasive and potential fruit pest that we knew was moving northwards from the southeastern USA.  Caitlyn grabbed a vial and we successfully had, on 10 September 2013, what we thought was the first capture of this fly in Ontario and Canada.

 Indeed the fly was Z. indianus, as determined by Meredith Miller, a M.Sc. student at the University of Guelph working on taxonomy of Drosophila spp. in Ontario.  Through contact with Hannah Fraser at Ontario Ministry of Agriculture Food and Rural Affairs, we learned that their Ontario-wide monitoring program for D. suzukii had also picked up some African fig flies in apple-cider vinegar traps, and a few at an earlier date than our find in Chatham-Kent.  Colleagues in Quebec (Jean-Phillipe Légaré and others at MAPAQ) had also found what they believed were Z. indianus.  Once all the material was collected and examined by Meredith, we submitted a scientific note documenting our Z. indianus discovery in Canada that was published by the Journal of the Entomological Society of Ontario.

Zaprionus indianus is native to the Afrotropical region.  It was found in Brazil in 1998 where it was given its common name because it became a significant pest of figs.  In 2005, Z. indianus was discovered in Florida and has since been found successively further north and west in the USA (see a map of its distribution here).  It is likely that the North American infestation did not come from the Brazilian population.  Zaprionus indianus is the only member of Zaprionus present in Canada, and therefore the reddish-brown head and thorax and particularly the silvery stripes that extend from the antennae to the tip of scutellum can be used as distinguishing features.

Zaprionis indianus dorsum showing characteristic white stripes

Unlike D. suzukii (thankfully!), female Z. indianus do not possess heavily sclerotized and serrated ovipositors and are not currently seen as a serious threat to temperate fruit crops.  They have been reared from a number of tropical, tree-ripened fruits in Florida and there is concern in vineyards in the eastern USA, where sometimes they outnumber D. suzukii in traps. It is possible that Z. indianus can use fruit that has been oviposited in by D. suzukii, thus increasing damage and possibly complicating control measures.  In Canada, particularly Ontario and Quebec, winter temperatures may preclude establishment of African fig fly, and yearly re-infestation from the south would be necessary for it to show up in future years.  At all but one site, we found just 1-4 flies during late summer and early fall per site, so it will be interesting to see what happens to numbers this coming growing season.  In tropical and sub-tropical locations much larger populations have been detected the year following first detection.

For the past 1.5 years I have been working as a post-doctoral fellow at the University of Guelph with Rebecca Hallett on D. suzukii.  We are developing a push-pull management strategy using volatile plant compounds to repel and attract this pest.  With the occurrence of Z. indianus and possible reoccurrence  in larger numbers in the future, we may have a unique opportunity to study how two recent invaders using similar resources interact, and also, perhaps, a more significant challenge ahead of us  in developing management strategies.  If you are interested in this topic or have current or future experiences with Z. indianus, I and co-authors on the scientific note would appreciate hearing from you.  You can contact me at renkemaj@uoguelph.ca.

By Scott Meers, Insect Management Specialist, Alberta Agriculture and Rural Development.

————————

My role as an entomologist with Alberta Agriculture and Rural Development consists largely of counting insects. We monitor the populations of seven different species on a provincial scale and several more on either an ad hoc or regional basis. We also carry out surveillance for potential new insect pests in crops. It is important to note that Alberta is a relatively large place, ranging 1066 km south to north and is 466 km at the widest. There are over 10,000,000 ha of land devoted to crop production. We do our monitoring work with two permanent staff and 2 to 3 summer students.

The first thing that becomes obvious is that we can’t do this work by travelling the entire expanse of the province. So we must communicate with those that are out in the fields and capture the results of their “footprints in the field”. Through various reporting systems we have had good success in developing a representative monitoring system. Check out our homepage at www.agriculture.alberta.ca/bugs-pest.

So where does Twitter fit in? In the two years that we have been using twitter we have collected nearly 800 farm related followers. Twitter is a great place to announce the results of our findings. If a set of traps or online reporting systems are reporting a concern we tweet it. The impact is instantaneous and widespread. Followers retweet (it is common for our in-season tweets to have 5 or more retweets), they ask questions, they check their fields and they let us know if their findings match ours. Talk about impact and talk about a reality check, it is awesome. We can then improve the quality and accuracy of the information we present.

We announce our new extension materials on Twitter. If we have a new You Tube video, radio broadcast (weekly during the growing season), new web page or even a chnage to our homepage, we tweet it. It is at least part of the reason we have over 2,000 hits on how to put together our Bertha Armyworm traps (we only put out 200 sets of traps across the province in 2012).

A big part of integrated pest management is the timing of insect activity. We have models for some insects and when they are supposed to be in their active scouting stage we tweet about it. Again instant feed-back! This helps us adjust and time our monitoring efforts to maximum efficiency. For those insects we don’t have models for we suggest timings based on experience. Agrologists and farmers tell us when they start seeing them. Again, awesome! Through Twitter we know when and where insects are showing up across the province. I am happy to retweet any credible source on insect activity and give credit where credit is due. A couple examples of this revolve around an outbreak of bertha armyworm (BAW) (Mamestra configurata) in central Alberta in 2012.

One case involves a comment about BAW in corn which is very unusual, partially because we have very little corn, and partially because BAW generally feeds on broadleaved plants. The conversation drew the attention of neighbors that were growing corn and they asked to see the field while we were inspecting it. The bottom line: the BAW laid their eggs on  lambsquarters which was uncontrolled under the canopy. The neighbors that had control of the lambsquarters had no BAW. Thanks to @landrashewski.

The second case was BAW in field peas, another relatively rare situation. The pictures tell the story though. There was substantial damage. If we have another BAW outbreak we will be sure to encourage producers to check their pea fields as well. Thanks to @Klams81.

Surveillance is where Twitter really shines. Last year I didn’t keep track of the requests for ID via Twitter but it was constant throughout the summer. There was a trend and repeats to the requests and there were questions about insects that we seldom see but were more common in 2012. Twitter gives us a chance to be in fields virtually. This a huge advantage because we can’t always be there in person.

We have also used Twitter to help us find fields to survey and to get permission from producers to access their fields. In addition we have recruited help from agrologists and farmers through Twitter. When we ask they are often happy to help us because they have been following us and the work we are doing. We also have several examples of people joining our monitoring network because of finding us on Twitter.

In short, Twitter is a valuable tool for monitoring insects in our program. We use it extensively. We welcome everything from the virtual coffee shop conversations to the private requests for identification. Twitter is, and will continue to be, an integral part of how we monitor insects in Alberta crops. It is good to be a part of the community and to give and receive in equal measure. We are looking forward to seeing what Twitter will bring in the new crop year!

What is this – a common Twitter question to @ABbugcounter last year. We reared it out and it turned out to be Pontia protodice or Checkered White Butterfly.
