摘要翻译：
通过对自由飞行的雄性埃及伊蚊、登革热和黄热病媒的高速视频观察，以及定制的测量方法，可以测量蚊子在飞行中的翅膀拍频、体位和体位。我们发现这些蚊子以大约850赫兹的频率拍打翅膀。我们还获得了标准偏差小于1度的身体偏航、身体俯仰和翅膀偏差测量结果，发现侧向速度和加速度是蚊子运动的重要组成部分。涉及飞行方向改变的快速转弯通常涉及大的侧向加速度。这些不对应于身体航向的相应变化，昆虫的飞行方向和身体航向在飞行过程中是脱钩的。这些发现要求质疑偏航控制在蚊子飞行中的作用。此外，利用方位数据，我们发现侧向加速度很好地解释了基于滚动的升力矢量旋转。相反，昆虫的身体俯仰角与向前加速度无关。这意味着控制身体滚动对蚊子的动态很重要。稳定身体俯仰和身体偏航的动态重要性不太清楚。

英文摘要：
  High speed video observations of free flying male Aedes aegypti mosquitoes, the dengue and yellow fever vector, along with custom measurement methods, enable measurement of wingbeat frequency, body position and body orientation of mosquitoes during flight. We find these mosquitoes flap their wings at approximately 850 Hz. We also generate body yaw, body pitch and wing deviation measurements with standard deviations of less than 1 degree and find that sideways velocity and acceleration are important components of mosquito motion. Rapid turns involving changes in flight direction often involve large sideways accelerations. These do not correspond to commensurate changes in body heading, and the insect's flight direction and body heading are decoupled during flight. These findings call in to question the role of yaw control in mosquito flight. In addition, using orientation data, we find that sideways accelerations are well explained by roll-based rotation of the lift vector. In contrast, the insect's body pitch angle does not correlate with its forward acceleration. This implies that controlling body roll is important to mosquito dynamics. The dynamic importance of stabilizing body pitch and body yaw is less clear.
