We just pulled together a quick summary of the various biological control activities our program has contributed towards...
AAFC-STB-Alberta-Beaverlodge Research Farm (Jennifer.Otani@agr.gc.ca) – The Pest Management program is active in annual and perennial field crops grown in the Alberta and BC portions of the Peace River region (i.e., 55-59 degrees North by 117-120 degrees West).
Historical projects include parasitoids/parasitism of Lygus spp. by Peristenus, Phasia aeneoventris; Delia spp. larvae in canola by Aleochora bilineata; coccinellid larvae by Oomyzus scaposus; cutworms in annuals and perennials grown for seed Apamea devastator, A. amputatrix, Nephelodes minians, Euxoa auxiliaris, Actebia fennica and more by various parasitoids and viruses; Coleophora deauratella and C. mayrella by Chelonus spp., Neochrysocharis formosa now placed in genus Omphale; Thymelicus lineola with zero observed parasitism over multiple years, Tychius meliloti, T. picirostris, T. stephensii with zero observed parasitism over multiple years, Hypera nigrirostris by Scambus hispae (tentative), Bathyplectes curculionis, B. exiguus; Sitodiplosis mosellana by Macroglenes penetrans, Platygaster sp., Inostemma walkeri.
Currently, the program supports R. DeClerck-Floate (AAFC-Lethbridge) with a release and post-release data collection on common toadflax near Grande Cache AB in 2022 plus we are following-up in 2024 by (i) confirming Oulema melanpus at larval feeding sites reported in 2023 in the Peace River region, and (ii) attempting to confirm larval parasitism levels.
Biological control topics relevant to the region needing support for the future include wheat midge parasitism, cereal leaf beetle parasitism, seed-feeding clover weevil parasitism, red clover casebearer parasitism, European skipper parasitism, plus the control of common toadflax, oxeye daisy, Canada thistle and kochia.
Thank you to Dr. O. Lonsdale (AAFC-Ottawa) who coordinates NIS submissions and to the many taxonomists who have helped us over the years!
