Root weevils have been causing increasing damage in Canadian commercial strawberry fields in the past few years with few options for managing their populations. As a first step in developing BMPs, a survey comparing monitoring methods was carried out in British Columbia, Ontario and Atlantic Canada. Fifteen species of root weevils were captured. Otiorhynchus sulcatus, the black vine weevil, was the most common species across the country. The strawberry root weevil, O. ovatus, was a problem in one field in BC, while Barypeithes pellucidus, the juniper root weevil, was collected in large numbers from two fields in Atlantic Canada. O. raucus was collected in Ontario, the first known record of this species feeding on strawberry. Pit fall traps captured the greatest number of individuals and worked well for O. sulcatus. However, visual sampling was best for O. ovatus which does not seem to enter pit fall traps.
