Incursions of highly destructive pest?s causes damage which have catastrophic effects to the agriculture crops, plants and native ecosystem. It explores various aspects of pest management and plant biosecurity focusing upon different response strategies for early detection, rapid response and risk assessment based upon advanced technologies like remote sensing and geographic information system (GIS). Pest Risk Analysis includes Pest Risk Area (PRA) and cost-benefit analysis (CBA) which guides decision making and resource allocation accurately. Biosecurity frameworks at national and international levels makes easy to co-ordinate responses among different areas. Rapid responses imply different strategies like containment (quarantine) and control (chemical/biological, prioritizing Integrated Pest Management ? IPM) and timely communication between locals, regional, state and central government agencies, academia is crucial to protect ecosystem in plant health emergency situations. All these emergency pest response strategies certainly face challenges which include interagency coordination gaps, pesticide resistance, and climate change impacts. Future directions involve genetic pest control, advanced detection methods (AI, molecular diagnostics) and strengthened international cooperation for more effective, sustainable, and resilient pest management.
