Survey parameters to support detection survey design for Anastrepha ludens

Since 2025, EFSA has conducted expert knowledge elicitations to estimate survey parameters for the detection of EU priority pests listed in Commission Delegated Regulation (EU) 2019/1702, in cases where pest‐specific information is lacking in the scientific literature. The design and implementation of statistically sound and risk‐based surveys require quantitative parameters such as sampling effectiveness, design prevalence and relative risk. This report presents the estimated values for Anastrepha ludens, together with the supporting evidence and expert rationale.
