In Arthropods of Canadian Grasslands (Volume 2): Inhabitants of a Changing Landscape. Biocontrol Arthropods: New Denizens of Canada's Grassland Agroecosystems. Adventive Biocontrol Agents (PDF, 67KB).In few historic occasions, and in current rare circumstances, natural predatorsВ have been able to follow their hosts into new habitats. the New Association or Neoclassical approach targets native pests with non-native biological control. is at 74%, which is higher than the average of about 60% reported for classical invasive plant biocontrol agents released elsewhere in the world, and even the average of 70% recorded for agents released in western Canada. biocontrol agents from the pests native range 2. Establishment of the purposely introduced species in B.C.

has records for 87 separate species, or 89 if strains of species are considered as separate biocontrol agents, having either been purposely introduced (72) or having found their way into the province (17) to target 38 invasive plants. Release of biological control agents into British Columbia began in 1951 with the introduction of Chrysolina quadrigemina (Suffrain) and C. Not all of the biological control agents the plant pathologists investigated proved superior, or even equal to, chem. Biocontrol researchВ and thereafter management effortsВ reunites these invasive plants with their natural enemies byВ importing agents, mainly insects, that feed on the plants from the native habitat. Invasive plant species targeted in B.C.В have been introduced from other continents, primarily Europe and Asia,В and have no natural enemies to attack them and keep them under control.
