Experimental Analyses of Body Morphology, Flight and Survival in Pierine Butterflies

小行星9419850 一些 昆虫种类不断积累， 或 有毒化学物质来阻止潜在的捕食者，而其他人则依靠速度 或 可操作性 逃跑 适口 和令人厌恶的蝴蝶种类往往在身体和翅膀形状、飞行速度和飞行机动性方面有所不同，但目前还不清楚这些特征是如何相互关联的，以及它们如何影响对捕食的脆弱性。 这项研究将使用体重分布的实验操作来测试关于体重和体型如何决定美味和难吃蝴蝶在实验室和野外条件下的飞行和生存的假设。 其中一种是重要的农业害虫。 这项研究将提供一个实验案例研究的目标和自然选择的机制，在昆虫的飞行和传播。

9419850 Kingsolver Some insect species accumulate distasteful or toxic chemicals to deter potential predators, while others rely on speed or manuverability to escape. Palatable and distasteful butterfly species tend to differ in body and wing shape, flight speed and flight manuverability, but it is unclear how these characters are interrelated and how they affect vulnerability to predation. This research will use experimental manipulations of the distribution of body weight to test hypotheses about how body weight and body shape determines flight and survival under lab and field conditions in both palatable and unpalatable butterflies. One of the study species is an important agricultural pest. The research will provide an experimental case study of the targets and mechanisms of natural selection that operate on flight and dispersal in insects.
