Adventive Biocontrol Agents
Adventive biological control agents are those that have arrived in BC by their own means. There are several scenarios for adventive agents in BC:
The collectability of adventive agents already known to exist in the province is included in the Summary of Agents in BC. However, upon finding a new adventive agent on an invasive plant species in Canada, weed biocontrol scientists or taxonomic experts should be consulted to first verify the identity of the organism and determine from where it possibly came. BC Ministry of Forests, Lands and Natural Resource Operations (FLNR) staff facilitate these activities for adventive agents found in BC. If an adventive agent is found in the province, provide a live specimen, if possible, or a preserved specimen, either correctly pinned or stored in 70% alcohol, to FLNR Invasive Plant Program staff. The recommended procedure for preserving an insect can be found in the publication The Insects and Arachnids of Canada Part 1, posted on the Entomological Society of Canada web site. Once the identity has been confirmed, the decision on whether redistribution of an adventive agent should occur will be done on a case by case basis.
An adventive agent to BC that has been approved for Canada (i.e. released in a different province) can be redistributed, however, its identity should be confirmed.
An adventive agent that has been approved for release in the USA, or has accidentally arrived in North America but has been present for some time, can be redistributed within Canada if it is known from either the literature or prior host-specificity test results to be safe to use (i.e. with respect to its recorded host range), and then only if the intended distribution area is within the same eco-zone as where it was found. If these conditions are in question, additional host specificity testing by scientists and petitioning of CFIA for release of the agent in Canada may be required.
Consult with FLNR Invasive Plant Program staff prior to redistributing new or unfamiliar adventive agents.
