Data from: Evaluating a Novel Core-and-Perimeter Delimiting Trapping Survey Design for Insects: I. Field Experiment

Published by Agricultural Research Service | Department of Agriculture | Metadata Last Checked: January 27, 2026 | Last Modified: 2025-11-26
We compared the "core and perimeter" (C&P) and "fully trapped" (FT) designs in a mark-release-recapture experiment with Ceratitis capitata (Weidemann; Diptera: Tephritidae) in Hawaii in 2022. Each design had four repetitions with four separate releases of flies, and six collection days from 1 to 14 days after release. The square FT grid had 99 traps over 0.92-km2, plus 24 “sentinel” traps just outside. The circular C&P grid had 20 core traps, and 108 traps in a 220 m-wide perimeter, set 500 m from the release point (smaller than the recommended radius).
