An ultrasonic stimulus induced negative phonotactic steering in the yaw axis of tethered, flying Australian field crickets. The forewings, hindwings and twisting of the thorax generated the forces which induced the yaw turn. However, abdominal ruddering did not contribute to yaw turns. Each aspect of the yaw steering response depended upon the stimulus intensity. At higher ultrasonic intensities, the magnitude and average angular velocity increased while the latency of the yaw turn decreased. Each of these factors varied in a graded manner, revealing that this behavior is more complex than a simple reflex.
超声刺激会使被束缚飞行的澳大利亚田野蟋蟀在偏航轴上产生负趋声转向。前翅、后翅以及胸部的扭转产生了导致偏航转向的力。然而，腹部摆动对偏航转向并无贡献。偏航转向反应的每个方面都取决于刺激强度。在较高的超声强度下，偏航转向的幅度和平均角速度增加，而偏航转向的潜伏期缩短。这些因素中的每一个都呈梯度变化，表明这种行为比简单的反射更为复杂。
