ABSTRACT Data obtained by sampling are crucial for decision making in crop loss assessment and pest management. Such data improve farmers' perceptions of the threat of pests and can, therefore, improve the quality of decision making in the practice of crop protection. The concept of a threshold, representing the dividing line between two alternative courses of action relating to seed or crop health, is an important aspect of crop protection decision making. Sampling is the means by which the required judgment can be guided. Operating characteristic curves are an important tool in the evaluation and comparison of the performance of sampling schemes. Precision integrated pest management, in which the objective is spatially variable pest management within fields, poses new problems for decision makers and statisticians developing sampling methodology in the context of crop protection.
摘要 通过抽样获得的数据对于作物损失评估和害虫管理中的决策至关重要。这些数据可以提高农民对害虫威胁的认识，从而提高作物保护实践中决策的质量。阈值的概念代表了与种子或作物健康相关的两种替代行动方案之间的分界线，是作物保护决策的一个重要方面。抽样是指导所需判断的手段。操作特征曲线是评估和比较抽样方案性能的重要工具。精确的害虫综合管理，其目标是在田间进行空间变化的害虫管理，给决策者和统计学家在作物保护背景下开发抽样方法带来了新的问题。
