The need
Whenever new pest management technology is introduced to a dynamic biological system such as crop production, the risk of potential resistance development within the pest population is a concern. For example, most scientists agree corn borer populations could potentially develop resistance to the various Bt proteins currently in Bt corn hybrids unless managed properly. As new technologies are introduced, similar concerns will arise and will need appropriate management strategies to protect long-term effectiveness. The CCPC is involved in conducting research on and addressing a variety of corn pest issues and their stewardship.
· Bt Events Approved for Unconfined Release in Canada
The solution
The CCPC's mandate to prolong the effectiveness of Bt technology prompted them to develop a thorough Insect Resistance Management (IRM) strategy, approved by the Canadian Food Inspection Agency, for corn growers. This proactive approach to managing Bt and other trait technology will effectively delay the development of insect resistance.
In addition to the Insect Resistance Management strategy, the CCPC has also developed a series of three protocols for the monitoring of ECB resistance through a detailed field scouting procedure, the handling of suspected resistant ECB larvae and remediation measures for confirmed resistance.

The members
Members of the CCPC include representatives from a number of seed and plant biotechnology companies, grower groups, extension personnel from provincial ministries of agriculture, research scientists from Agriculture and Agri-Food Canada and the University of Guelph. Representatives of the Canadian Food Inspection Agency's Plant Biosafety Office participate as observers. The group meets face-to-face twice a year, in the spring and fall. A comprehensive list of member organizations, their representatives and contact information is available.
