Hello,
The Common Names Committee of the Entomological Society of Canada, in collaboration with the Canadian Wildlife Service (Environment Canada), is planning a project to develop common names for all beetles in Canada. We are looking for to hire contractors to assist in developing English and French common names.  Since this order contains many families, we are looking for Anglophone and Francophone Coleopterists who specialize in more than one group of Coleoptera species.  Compensation will be based on the number of species assigned to each contractor.  If interested, please send your C.V. to Joanna.James@ec.gc.ca by August 16th, 2013.  Please do not hesitate to contact us if you have any questions.
Thanks!
Bonjour,
Le Comité des noms communs de la Société d’entomologie du Canada, en collaboration avec le Service canadien de la faune (Environnement Canada) prépare un projet pour développer des noms communs pour tous les coléoptères au Canada. Des experts seront engagés pour développer les noms communs en anglais et en français. Puisque cet ordre contient plusieurs familles, nous cherchons des experts anglophones et francophones qui se spécialisent sur plus d’un groupe d’espèces de coléoptères. La rémunération sera basée sur le nombre d’espèces assignées à chaque expert. Si intéressé, svp envoyer votre C.V. à Joanna.James@ec.gc.ca  avant le 16 août, 2013. Svp n’hésitez pas à nous contacter si vous avez des questions.
Merci!

A few weeks ago my most recently graduated Master’s student took a few days off to attend the UNBC convocation ceremony. Knowing her former supervisor’s fondness of red wine (which several of my other graduate students have magically discovered as well – go figure!), and no doubt well mentored in the important aspects of oenology by her entomologist father, she kindly presented me with a bottle of Idaho wine aptly named “Entomology”. The vineyard in question has a series of ‘ology’ wines, and appropriately, the importance of entomology has been recognized in this one. This welcome gift, along with other wines I had purchased solely because they had an insect on the label, caused me to ponder the connection between insects and wine. It should be added that apart from a long-standing preference of certain varieties of red wine, label design and price are pretty much my only criteria for selection of wines to purchase, as my olfactory senses have long been impaired after years of sinus infections.

Insects have had enormous significance in viticulture. Interestingly, pollinators do not appear to play a significant role, as the wine grape, Vitis vinifera L. (Vitaceae) is primarily wind pollinated. The negative impact of one insect on viticulture, on the other hand, provides for a fascinating story of applied interdisciplinarity, long before that concept became a fad. In an entomological detective story, elements of international politics, bureaucratic intrigue, the struggle between Darwinian evolution and creationism, invasive insect ecology, plant resistance, systematics, are interwoven like a movie script leading to the establishment of the fledgling discipline of economic entomology, with several entomologists the heroes (prominent among them Charles V. Riley) saving the damsel in distress (French viticulture) (Sorensen et al. 2008). I speak of course of the impact of the grape phylloxera, Daktulosphaira vitifoliae (Fitch) (Hemiptera: Phylloxeridae), an introduced insect from North America, on the French wine industry. At one point this little insect threatened the very existence of the industry, which at the time supported a sizeable portion of the French economy (Smith 1992, Sorensen et al. 2008). A simple Google Scholar search reveals that phylloxera remains a significant issue and is subject to continuing research worldwide (Granett et al. 2001). Corrie et al. (2002) even noted that phylloxera “is a viticultural pest that in the past has devastated vineyards worldwide, yet little is known about this insect’s biology”.

Apart from the “Entomology” wine, which I haven’t tasted yet, I have four other wines, falling in two categories. Two are organic wines, and have butterflies on the label, while the other two labels are adorned by ants. The descriptions below are from other sources, as my inferior olfactory system cannot do wines justice. Suffice it to say I like them all.

Five wines with labels adorned with insects. In today’s wine market, it seems that eye-catching labels are important competition tools. I wonder if entomophobic customers buy any of these?

Nuevo Mundo Reserva Cabernet-Malbec represents the type of wine I enjoy with a “big bouquet of dark cherries and blackberry with hints of sweet spice on the palate” (hint to future students!).  The labels of all their wines have butterflies, no doubt signifying that it is an organic product and certified 100% carbon neutral. This wine is produced in the Maipo Valley, Chile, aged in French oak for a year, and sold for slightly under $16 in BC Liquor stores.

Domino de Punctum Lobetia is an organic Tempranillo wine produced by the Punctum Estate in La Mancha, Spain. It is described as having a “cherry colour with a violet shade indicating its youth. On the nose you’ll find fresh cherries and other red berries, with similar notes on the palate that shows moderate tannins”, and for $12.99 this is a very price-worthy wine.

Fabulous Ant is a Pinot Noir from Tolna, Hungary, which at $12.99 is a great buy. I have not been a fan of Pinot Noir, but I quite enjoy this wine described as having “cherry, strawberry and clove aromas on the nose and a silky, medium-bodied palate”. The label features an ant carrying a cherry, rather than a grape, perhaps indicating the predominance of cherry. This is a wine that I would not have picked as Hungary doesn’t strike me as a primary wine producing country, at least not of the types of wine I enjoy. However, this wine was awarded a Gold Medal at the Berlin Wine Show 2013, reflecting the emergence of yet another interesting wine producing region worth paying attention to.

Formiga de Vellut is a Carignan-Grenache-Syrah blend from the Priorat region in Spain, and is the most expensive of the wines I have chosen. At under $30 it is still worthy of a try by any entomologically inclined wine aficionado, however. I rarely spend that much on wine, but with ants on the label, how can I resist? It is described by Anthony Gismondi (http://www.gismondionwine.com/), who gave it a rating of 91 points, as a “spicy, floral, curry, black peppery, liquorice scented red.” He goes on to write: “Love the dry, supple palate and its smoky, peppery, black cherry jam and meaty, licorice and cedar flavours.” I agree with Mr. Gismondi (at least with respect to what I am able to perceive)!

Finally, the interesting Idaho wine Entomology. Produced by the Cold Springs Winery located halfway between Boise and Twin Falls, Idaho, this is a Cabernet-Syrah blend which according to the vineyards own website is a medium bodied wine with red fruits and dried figs on the nose and blueberry on the palate. The label depicts a Polyphemus moth, which is described as a “pollinator moth”, so the entomology part may be a bit off target, but hey, if the wine is good we can live with some slight miscues.

There are obviously many other wines with an insect connection that I have not seen. I am hoping for suggestions in response to this blog post! Actual samples are welcome as well….

I am pleased to present the “Editor’s Pick” manuscript for the current issue of The Canadian Entomologist. This pick was a paper by Bob Lamb, Patricia MacKay and Andrei Alyokhin, titled “Seasonal dynamics of three coexisting aphid species: implications for estimating population variability

I had always admired the ongoing work on aphids, spearheaded by Bob and Pat. Their work is always relevant, meticulous, framed in an important and broader ecological context, and they have a ‘model system’ to work with. This is the kind of researcher many more junior entomologists look up to.  The current paper is no exception. In this work, Bob and Pat joined up with Andrei Alyokhin and present a careful study of population variability and effectively use this metric to better understand population dynamics over time.  For me, I see much value in this approach, and can see how this kind of work could effectively be used in teaching students about how to best describe, understand, and quantify population dynamics.  I’m also inspired to see long-term data with arthropods. These kinds of data are so useful, but relatively rare. It’s great to see Bob, Pat and Andrei publish thoughtful and important work using such data.  I may also look around some old filing cabinets at my University…

Bob was kind enough to answer a few questions about this work, with input from his co-authors.

What inspired this work?

When Pat MacKay and I were anticipating eventual retirement from paying jobs as entomologists, we decided to begin a study of an aphid population that could be pursued as long as we could walk trails and count aphids. Our goal was to figure out why aphid populations seem to be so unstable. Eventually we wrote up our findings on the stability of one native species over the first 10 years of a study we hope will go on for at least another 10 years. A few years ago we realized we needed comparative data, but were too old to start on a 20-year study of another aphid species. The solution was to write to colleagues who also had long-term data sets, to see if they were interested in looking at their data from this perspective. So far the colleagues we have contacted have been enthusiastic collaborators. The first was Andrei Alyokhin our coauthor on the current paper. He gave us access to 60 years of data on three aphid species. The first paper on the stability of these aphids was published in the Canadian Entomologist two years ago. The current paper extends that earlier work, looking now at how aphid seasonal biology affects our estimates of stability.

What do you hope will be the lasting impact of this paper?

We hope that this paper will help convince other researchers that Joel Heath’s metric, PV, which we use to quantify population variability, is a robust way to quantify one aspect of the stability of populations. If more researchers adopt this metric, ecologists will have a much greater opportunity to apply a comparative approach and identify factors that contribute to stability or instability of populations.

Where will your next line of research on this topic take you?

Pat MacKay and I continue to extend our time series on the abundance of a native aphid, and are now focusing more on the ecological processes that cause our five populations to rise and fall. We also hope to expand our studies of stability to still more aphid species, but also species with very different life histories. At the moment I am working with a colleague, Terry Galloway, University of Manitoba, on several time-series of ectoparasite abundance on birds.

Do you have any interesting anecdotes about this research?

One of the most interesting aspects of the work on aphids from potatoes is the source of the data – 60 years or more of weekly aphid counts. The data for the early years were discovered by Andrei Alyokhin in an abandoned filing cabinet stored in a barn at the University of Maine. Andrei was a new faculty member at the time exploring his research facilities. His predecessors had maintained meticulous records of aphid densities in potato plots since soon after World War II. Andrei was quick to recognize the value of this data, and more importantly recognized the need to go on collecting the data in the same way. The result is an amazing data set, one of the longest continuous records at one location of the dynamics of multi-voltine species.

Lesson 1: newly-hired entomologists should begin their careers by searching old filing cabinets.

Lesson 2: meticulous long-term records can be invaluable, sometime in ways that you might not anticipate.
