Heilipus lauri Boheman (Coleoptera: Curculionidae) is a specialist pest of avocado fruit and is considered an incursion risk for U.S. avocado producers. At the time work reported here was undertaken the flight capabilities of H. lauri were unknown. Consequently, proactive studies were undertaken to quantify aspects of this pest's flight capabilities to inform potential future control efforts. Flight mill studies were conducted in a quarantine laboratory to measure the dispersal capacity of H. lauri with respect to gender, mating status, and size on the single and repeat flight capabilities of weevils. Gender, mating status, and size did not significantly affect measured flight parameters. Average total distances flown and flight velocity, and mean maximum flight bout distances and durations significantly declined as weevil age increased and when weevils engaged in repeat flights. Survivorship rates were significantly reduced as the number of successive flights undertaken increased. The distribution of total average flight distances flown and total cumulative flight distances flown was platykurtic. The implications of these findings are discussed in terms of developing incursion management plans.

对 Heilipus lauri Boheman（鞘翅目：Curculionidae）单次和重复飞行能力的年龄、性别、交配状态和大小的评估。

Heilipus lauri Boheman (Coleoptera: Curculionidae) 是鳄梨果实的一种特殊害虫，被认为是美国鳄梨生产商的入侵风险。在此报告的工作进行时，H. lauri 的飞行能力是未知的。因此，进行了积极的研究以量化这种害虫的飞行能力，为未来的潜在控制工作提供信息。飞行磨坊研究在检疫实验室进行，以测量 H. lauri 在性别、交配状态和大小方面对象鼻虫单次和重复飞行能力的传播能力。性别、交配状态和大小对测量的飞行参数没有显着影响。平均总飞行距离和飞行速度，随着象鼻虫年龄的增加和象鼻虫进行重复飞行，平均最大飞行距离和持续时间显着下降。随着连续飞行次数的增加，幸存率显着降低。总平均飞行距离和总累计飞行距离的分布呈扁平状。在制定入侵管理计划方面讨论了这些发现的影响。
