Maximum vertical force production (F) is an integral measure of flight performance that generally scales with size. Numerous methods of measuring F and body size are accessible to entomologists, but we do not know whether method selection affects inter- and intraspecific comparisons of F-size scaling. We compared two common techniques for measuring F in bumblebees () and mason bees (), and examined F scaling using five size metrics. F results were similar with incremental or asymptotic load-lifting, but scaling analyses were sensitive to the size metric used. Analyses based on some size metrics indicated similar scaling exponents and coefficients between species, whereas other metrics indicated coefficients that differed by up to 18%. Furthermore, F showed isometry with body lengths and fed and starved masses, but negative allometry with dry mass. We conclude that F can be measured using either incremental or asymptotic loading but choosing a size metric for scaling studies requires careful consideration.
最大垂直力产生量（F）是飞行性能的一个综合指标，通常与体型大小相关。昆虫学家有多种测量F和体型大小的方法，但我们不知道方法的选择是否会影响F-体型大小缩放的种间和种内比较。我们比较了两种测量熊蜂（ ）和壁蜂（ ）的F的常用技术，并使用五种体型指标研究了F的缩放情况。增量或渐近式举重测量的F结果相似，但缩放分析对所使用的体型指标很敏感。基于某些体型指标的分析表明，物种之间的缩放指数和系数相似，而其他指标表明系数差异高达18%。此外，F与体长、取食和饥饿状态下的质量呈等比关系，但与干质量呈负异速生长关系。我们得出结论，F可以使用增量或渐近加载来测量，但为缩放研究选择体型指标需要仔细考虑。
