Insect pectinate antennae are very complex objects and studying how they capture pheromone is a challenging mass transfer problem. A few works have already been dedicated to this issue and we review their strengths and weaknesses. In all cases, a common approach is used: the antenna is split between its macro- and microstructure. Fluid dynamics aspects are solved at the highest level of the whole antenna first, ie, the macrostructure. Then, mass transfer is estimated at the scale of a single sensillum, ie, the microstructure. Another common characteristic is the modeling of sensilla by cylinders positioned transversal to the flow. Increasing efforts in faithfully modeling the geometry of the pectinate antenna and their orientation to the air flow are required to understand the major advantageous capture properties of these complex organs. Such a model would compare pectinate antennae to cylindrical ones and may help to understand why such forms of antennae evolved so many times among Lepidoptera and other insect orders.

通过梳状天线模拟信息素捕获的挑战

昆虫的梳状触角是非常复杂的物体，研究它们如何捕获信息素是一个具有挑战性的传质问题。一些作品已经致力于这个问题，我们回顾了它们的优点和缺点。在所有情况下，都使用一种通用方法：天线在其宏观和微观结构之间分开。流体动力学方面首先在整个天线的最高层次上得到解决，即宏观结构。然后，在单个感器（即微观结构）的尺度上估计传质。另一个共同特征是通过横向于流动定位的圆柱体对感受器进行建模。为了理解这些复杂器官的主要有利捕获特性，需要加大对梳状天线的几何形状及其对气流方向的忠实建模的努力。
