However, such datasets do not adequately evaluate long-term identity preservation, where objects must be tracked consistently over extended durations. We introduce WaspMOT, a benchmark designed to address this gap through long-duration tracking of Trichogramma wasps in controlled ecological experiments. The dataset contains 10 sequences of approximately 12,000 frames each (over 8 minutes at 25 FPS), with dense MOTChallenge annotations and oracle detections to isolate association performance.  \nUnlike existing benchmarks, WaspMOT forms a closed-set tracking scenario where all individuals remain present throughout the sequence, requiring consistent identity assignment across thousands of frames despite abrupt jumps, occlusions, and highly similar appearance. We establish a benchmark by evaluating five tracking-by-detection methods, including ByteTrack, BoTSORT, C-BIoU, OC-SORT, and McByte, under a unified protocol. Results show that all methods suffer from significant trajectory fragmentation, highlighting the difficulty of long-term identity preservation even with perfect detections. A simple spatial tracklet stitching baseline consistently improves performance, indicating that substantial gains remain possible.  \nWaspMOT provides a new benchmark for studying long-term association and reveals limitations of current tracking approaches that are not observable on conventional datasets. The benchmark will be made publicly available at the project repository: [https://github.com/tstanczyk95/WaspMOT/](https://github.com/tstanczyk95/WaspMOT/).  \nIndex Terms—multi-object tracking, long-term tracking, ecological surveillance, benchmark dataset  \nI. INTRODUCTION  \nMulti-object tracking (MOT) is a fundamental computer vision problem with applications in video surveillance, autonomous driving, robotics, and sports analytics. Its objective is to detect objects and maintain consistent identities overtime. Recent progress has been driven by benchmark datasets focusing on human-centered scenarios, including pedestrian tracking [1], [2], sports tracking [3], [4], and human motion analysis [5] . These datasets have enabled robust tracking algorithms capable of handling occlusions, appearance changes, and moderate motion.  \nFig. 1. Sample frame of a video with individuals inside an experimental arena. The image pixel dimensions are indicated in black and the real arena dimensions are indicated in red.  \nHowever, existing MOT benchmarks are dominated by short sequences, typically lasting tens of seconds, where trajectories span only a limited portion of the video. As a result, trackers are primarily evaluated on short-term association rather than long-term identity preservation. This limits the ability to study scenarios where identities must be maintained consistently over extended durations. In ecological and biological monitoring, such long-term identity consistency is essential for analyzing individual behaviors and interactions.  \nTo address this gap, we introduce WaspMOT, a dataset designed for long-duration multi-object tracking of Trichogramma wasps in laboratory-controlled experiments. Each sequence contains approximately 12,000 frames (over 8 minutes at 25 FPS), and all individuals remain present throughout the entire video, forming a closed-set tracking","cbCaiakqLxV4Agx7","https://ap.wps.com/l/cbCaiakqLxV4Agx7","pdf",736863,4,1,6,"English","en",105,"# Abstract\n# I.
