A new invasive weevil that is turning berry buds into duds in British Columbia
By Michelle Franklin, Paul Abram, and Tracy Hueppelsheuser
Most of the weevils we find in raspberry and strawberry fields in the Fraser Valley of British Columbia (BC) are nocturnal, so you would be hard pressed to find adult weevils without venturing out at night with your headlamp or flashlight. However, in 2019 a curious small black weevil was observed during the day in a backyard raspberry patch in Abbotsford, BC.
The first specimens of this weevil were collected by Provincial Entomologist and coauthor, Tracy Hueppelsheuser from the BC Ministry of Agriculture, Food and Fisheries and sent to taxonomists and co-authors, Dr. Patrice Bouchard from the Canadian National Collection and Dr. Robert Anderson from the Canadian Museum of Nature for their expert identification. It turned out that this weevil was indeed new to the Fraser Valley, BC. This tiny (2.5 – 3mm), black, long nosed weevil was the strawberry blossom weevil, Anthonomus rubi, which is native to Europe, Asia, and North Africa. This was the first observation of this species in North America.
Strawberry blossom weevil is not just a pest of strawberries. It is able to feed and reproduce on a wide variety of plants in the family Rosaceae, including other economically important berry crops such as raspberries and blackberries. Adult weevils overwinter in the leaf litter and become active in the spring. After mating, the female chews a hole inside a closed flower bud, lays her egg inside, and then clips the stem below, killing the bud and preventing fruit development. The weevil larva then develops inside the bud and emerges as an adult about a month later when temperatures are warm in the summer. In its native range, the weevil completes a single generation each year.
I started my position as a research scientist in July 2020, specializing in small fruit entomology and Integrated Pest Management at the Agassiz Research and Development Centre of Agriculture and Agri-Food Canada. With help from Paul Abram (Agriculture and Agri-Food Canada), Tracy Hueppelsheuser (BC Ministry of Agriculture, Food and Fisheries), and crop consulting company, ES Cropconsult we hit the ground running, completing surveys in the Fraser Valley in the summer 2020 to determine the distribution and associated host plants of the strawberry blossom weevil. We found adult weevils on cultivated plants (e.g. strawberry, raspberry, blackberry, and rose) and wild hosts (e.g. salmonberry, thimbleberry, Himalayan blackberry, and wild rose). Our survey found this species to be well established throughout the Fraser Valley from Richmond to Hope.
However, there is some good news for potential natural pest control. Later during the summer we saw parasitoid wasps around weevil-damaged Himalayan blackberry buds. We knew that some species of parasitoid wasps had the potential to be natural enemies of the weevil. Parasitoid wasps lay eggs on weevil larvae and their offspring often develop on the larvae resulting in their death. This behaviour has been successfully used as biological control of other weevil pests for decades. Hence, we initiated natural enemy surveys by collecting damaged buds from the field. Although COVID protocols restricted lab access, I monitored damaged buds in my temporary laboratory (a.k.a home garage) and within a few weeks parasitoids emerged! Over the summer, we had over 150 parasitoids emerge from strawberry blossom weevil damaged buds. With the help of taxonomist and co-author, Dr. Gary Gibson from the Canadian National Collection, we identified the metallic-colored parasitoid to the genus Pteromalus. Future work is needed to identify the parasitoid to the species level, determine its origin (native to North America or inadvertently introduced from another continent), and determine its impact on strawberry blossom weevil populations.
I am continuing to work with my co-authors to understand the biology of this new pest and its natural enemies, with the goal of using this knowledge to develop sustainable pest management strategies in the future.

Meeting announcement – International Society of Chemical Ecology
We would like to invite you to attend the annual general meeting 5-10 September, 2021. For the first time ever the ISCE annual meeting will be an entirely virtual meeting but numerous mechanisms have been built into the program and platform being used to host the meeting, to facilitate interaction by delegates with each other and the content. The theme of the conference “Chemical Ecology and Sustainable Development” emphasizes the immense potential chemical ecology has to both inform our understanding of the natural world and the potential for practical applications.
Please visit the meeting website (https://isce2021.carlamani.com/) to view the program and register. In addition to being able to participate in the live event 5-10 September, registration provides delegates the opportunity to view talks for 2 months after the meeting. We look forward to seeing you virtually at the meeting. Please don’t hesitate to contact the meeting organizers if you have any questions or concerns.
Best wishes,

Graduate Student Showcase 2021: Call for Applications
Graduate students are invited to apply to present their research at the Graduate Student Showcase (GSS), held during the Joint Annual Meeting of the Entomological Society of Canada and the Entomological Society of Ontario (Nov 15-18, 2021). The purpose of the GSS is to provide a high-profile opportunity for graduate students near the completion of their degrees to present a more in-depth overview of their thesis research.
Applicants to the GSS must:
have defended or plan to defend their thesis at a Canadian University within one year of the meeting
be the principal investigator and principal author of the presented work
be registered at the meeting
Eligible candidates who wish to be considered for the GSS must submit a complete application to students@esc-sec.ca, following the instructions below. Items 1-3 must be submitted in a single PDF file named in the format “FamilyName_GSSapplication.pdf”.
1) Submit a 250 word abstract describing the proposed presentation highlighting their work,
2) Submit a 1 page (single-spaced, 12 point) outline of their research, including rationale/significance, methodology, and results to date,
3) Include a CV that includes a list of previous conference presentations and other presentation experience.
4) Arrange to have the principal supervisor email a letter of support in a PDF file that confirms the anticipated or actual date of graduation and comments on the proposed presentation and the applicant’s presentation and research abilities. Please ask your supervisor to name the letter of support in the format “FamilyName_GSSLetterOfSupport.pdf”, where Family Name is the applicant’s family name.
In addition to the above materials, applicants are welcome – but by no means required – to submit supplementary information about any factors that may have influenced their application (e.g., factors that may have limited access to publication or presentation opportunities). Please note that the supplementary information will be considered confidential, being viewed exclusively by members of the Graduate Student Showcase Selection Committee.
The GSS application deadline falls on the same day as the annual meeting deadline for contributed talks. For the 2021 GSS, all application materials must be submitted by September 13, 2021. We will select up to four (4) recipients. All applicants will be notified of the status of their application. Unsuccessful applicants to the GSS will have their talks automatically moved to a President’s Prize Oral session.
Differences between the GSS and the President’s Prize (PP) Competition include:
The GSS will take place in its own dedicated time slot; there will be no conflicting talks!
Presenters in the GSS are given more time to speak about their research (28 minutes total, 25 for the presentation & 3 for questions)
Abstracts for talks presented in the GSS are published in the ESC Bulletin, an open access publication, received by all ESC members.
The selection process for the GSS is competitive (only selected students speak), compared to the PP where all students who enter speak but only one per category receives a prize.
All presenters in the GSS receive an honorarium of $200.
We encourage and welcome applications from all eligible individuals, especially those who identify with groups that are underrepresented in STEM and entomology. The Entomological Society of Canada values diversity in all its forms and seeks to represent the breadth of Canadian entomological research and researcher identities through its GSS. Supervisors, please encourage your students to apply and please help us to spread the word! Any questions can be directed to students@esc-sec.ca.
