适应性个体行为（“动物人格”）的研究重点是个体在（相关的）行为中是否始终存在差异以及个体层面的行为是否受到选择。选择影响人格的证据偏向于可以在野外轻松收集行为和生活史信息的物种，例如有蹄类动物和雀形目鸟类。在这里，我们报告了对昆虫（田蟋蟀；Gryllus Campestris）在野外表现的行为的重复性和综合症结构的估计。我们使用标记重捕获模型来估计与人格相关的生存和遭遇概率，并重点关注所有个体都可以轻松采样的生活史阶段（若虫阶段）。作为危险行为的代表，我们分析了距洞穴的最大距离、飞行起始距离和干扰后的出现时间；所有行为都是可重复的，但没有证据表明有很强的综合症结构。仅飞行起始距离就可以预测每日生存率和遭遇概率：胆大的个体更容易观察到，但寿命较短。个体在进行检测的栖息地温度下也具有一定的可重复性。这种环境的可重复性可能会导致行为可重复性的估计出现向上偏差；事实并非如此。然而，行为分析是围绕受试者的个人洞穴进行的，如果洞穴特征影响行为，则可能会导致伪重复性。后续易位实验使我们能够区分个体和洞穴身份效应，并为个体飞行起始距离的可重复性提供确凿的证据。因此，我们的研究结果有力地证明了野生昆虫存在性格差异，并且它与健康的组成部分有关。
The study of adaptive individual behavior (“animal personality”) focuses on whether individuals differ consistently in (suites of correlated) behavior(s) and whether individual-level behavior is under selection. Evidence for selection acting on personality is biased toward species where behavioral and life-history information can readily be collected in the wild, such as ungulates and passerine birds. Here, we report estimates of repeatability and syndrome structure for behaviors that an insect (field cricket;Gryllus campestris) expresses in the wild. We used mark-recapture models to estimate personality-related survival and encounter probability and focused on a life-history phase where all individuals could readily be sampled (the nymphal stage). As proxies for risky behaviors, we assayed maximum distance from burrow, flight initiation distance, and emergence time after disturbance; all behaviors were repeatable, but there was no evidence for strong syndrome structure. Flight initiation distance alone predicted both daily survival and encounter probability: bolder individuals were more easily observed but had a shorter life span. Individuals were also somewhat repeatable in the habitat temperature under which they were assayed. Such environment repeatability can lead to upward biases in estimates of repeatability in behavior; this was not the case. Behavioral assays were, however, conducted around the subject’s personal burrow, which could induce pseudorepeatability if burrow characteristics affected behavior. Follow-up translocation experiments allowed us to distinguish individual and burrow identity effects and provided conclusive evidence for individual repeatability of flight initiation distance. Our findings, therefore, forcefully demonstrate that personality variation exists in wild insects and that it is associated with components of fitness.
