研究了四种新热带蝗虫的超声波产生及其接收情况。 1和P.sp。 2号以每秒35至40次和40至45次的速度移动前翅，并通过翅膀的闭合运动发出声音。颤音主要分别为 44-50 和 46-56 kc/s。声音成分几乎不包括在内。对于P.sp，由牙齿和刮刀之间的冲击引起的牙齿脉冲的速率约为650/秒。 P.sp. 1 和约 800/秒2.距昆虫背外侧约10cm处，鸣声强度为100～110dB(re 0·0002dyn/cm2)。Drepanoxiphusmodeus(Bruner)通过闭合前翅发出鸣声。与 Phlugis 不同的是，齿脉冲相互融合成 22-24 kc/s 的纯音脉冲。 10厘米距离处强度为98至102分贝。Conocephalus saltator（索绪尔）以30次/秒的速度移动翅膀，并通过前翅的张开和闭合运动发出声音。打开翅膀时产生的声音比关闭时产生的声音强度低约 20 dB，并且强烈包含 18-42 kc/s 的频率，而关闭时声音的主要频率约为 40 和 60-66 kc/s。这些物种的鼓膜器官的最佳灵敏度在 20 至 25 kc/s 之间。 C 的最小阈值约为 30 dB。跳跃者和其他三个物种约 40 分贝。在所有四个物种中，位于大脑和后胸神经节之间的中央听觉大纤维接收来自同侧鼓室神经的兴奋性输入和来自对侧鼓室神经的抑制性输入。
Ultrasonic production and its reception in four species of neotropical grasshoppers were studied.Phlugissp. 1 andP.sp. 2 moved the forewings at the rate of 35 to 40 and 40 to 45/sec and produced sounds by closing motion of the wings. The stridulatory sounds dominantly included 44–50 and 46–56 kc/s, respectively. The audible components were scarcely included. The rate of tooth-pulses which were caused by impact between the teeth and the scraper was about 650/sec forP.sp. 1 and about 800/sec forP.sp. 2. The intensity of the stridulation was 100 to 110 dB (re 0·0002 dyn/cm2) at about 10 cm from the dorso-lateral side of the insect.Drepanoxiphus modestus(Bruner) emitted stridulatory sounds by closing the forewings. As distinct fromPhlugis, the tooth-pulses fused each other into a pure tone pulse of 22–24 kc/s. The intensity was 98 to 102 dB at 10 cm distance.Conocephalus saltator(Saussure) moved the wings at a rate of 30/sec and made sounds by both opening and closing movements of the forewings. The sound produced by opening the wings was about 20 dB less intense than that by closing and strongly included the frequencies 18–42 kc/s, whereas the dominant frequencies of the sound during closing was about 40 and 60–66 kc/s.The optimum sensitivity of the tympanic organs of these species was between 20 and 25 kc/s. The minimum threshold was about 30 dB forC. saltatorand about 40 dB for the other three species. In all four species, the central auditory large fibres which lie between the brain and metathoracic ganglion received excitatory input from the ipsilateral tympanic nerve and inhibitory input from the contralateral tympanic nerve.
