Crop production had dominated the Canadian Prairies for the past century, and has been constantly challenged by various pathogens, insects, and weeds. An effective biovigilance program to manage these crop pests requires continuous, timely, and detailed pest surveillance, to understand how pest populations are changing over time. Many of these pests have been managed through surveillance and various mitigation strategies, combined with follow-up analyses. Pest surveillance activities have been documented in the Canadian Prairies for over 100 years and analysis has progressed from determining the pest species involved, to understanding the damage they cause, their biology, spread, over-wintering strategies, reproduction, pesticide resistance, and genetic diversity. This research has generated a continuous history of the pest populations for crops in western Canada. Detailed virulence analysis has revealed pathogen evolution and adaptation to overcome some of the deployed host resistance genes. Some weed, insect, and plant pathogenic fungal species have evolved to become resistant to pesticides. Integration of pest surveillance activities will help to build a more responsive, robust, and reliable biovigilance program to manage crop pests in the Canadian Prairies.

在过去的一个世纪里，作物生产一直主导着加拿大大草原，并不断受到各种病原体、昆虫和杂草的挑战。管理这些作物害虫的有效生物警戒计划需要持续、及时和详细的害虫监测，以了解害虫种群如何随时间变化。其中许多害虫已通过监测和各种缓解策略以及后续分析进行管理。加拿大大草原的害虫监测活动已有 100 多年的记录，分析已经从确定所涉及的害虫种类发展到了解它们造成的损害、其生物学、传播、越冬策略、繁殖、农药抗性和遗传多样性. 这项研究产生了加拿大西部作物害虫种群的连续历史。详细的毒力分析揭示了病原体进化和适应以克服一些部署的宿主抗性基因。一些杂草、昆虫和植物病原真菌物种已经进化成对杀虫剂具有抗性。有害生物监测活动的整合将有助于建立一个反应更快、更强大和更可靠的生物警戒计划，以管理加拿大大草原的农作物有害生物。
