Abstract
The hindwing geometry, aspect ratio, and numerical modeling of susceptible, Bt-Corn- and rotation-resistant western corn rootworm (WCR) wings was investigated. All variants had similar hindwing geometries and aspect ratio (AR: 6-7). These AR values correspond to wings suited to lower altitude flights of a shorter distance. These AR values are characteristic of wings that can carry heavier loads and are capable of precision flying. Numerical modeling using the finite element method (FEM) showed that the Bt-Corn-resistant and rotation-resistant WCR hindwings could potentially resist higher wind speeds with minimal deformations compared to conspecific susceptible WCR. Understanding the physiology and dispersal of resistant WCR enables a better understanding of how these variants spread their alleles across large scale agricultural landscapes. This may have important implications for integrated resistant management strategies for WCR.
研究了易感、Bt-玉米螟和抗轮作西部玉米根虫（WCR）后翅的几何形状、长宽比和数值模型。所有变体都具有相似的后翅几何形状和长宽比（AR：6-7）。这些 AR 值与适合短距离低空飞行的翅膀相对应。这些 AR 值是可承受较重负荷并能进行精确飞行的机翼的特征。使用有限元法（FEM）进行的数值建模表明，与同种易受影响的WCR相比，抗Bt-Corn和抗旋转的WCR后翅有可能以最小的变形抵抗更高的风速。了解了抗性 WCR 的生理和扩散情况，就能更好地理解这些变种如何在大规模农业景观中传播其等位基因。这可能会对 WCR 的综合抗性管理策略产生重要影响。

期刊介绍：
Insects (ISSN 2075-4450) is an international, peer-reviewed open access journal of entomology published by MDPI online quarterly. It publishes reviews, research papers and communications related to the biology, physiology and the behavior of insects and arthropods. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
