摘要雄雏蝗产生的歌句包含两种不同的结构元素--第一部分（A）中的脉冲音节和第二部分（B）中的持续噪音。雌性的Ch. dorsatus回答人工的歌曲模型，只有当两个元素A和B都存在。女性强烈喜欢歌曲模式中的元素的顺序是A前B。女性主要是通过A音节中存在的空白来区分这两个成分。由8-15 ms的间隙分隔的5-8 ms的脉冲产生最有效的A-音节，而音节持续时间和音节间隔是不太重要的参数。女性对包含3个以上A音节的模型的反应概率很高。女性模型的偏好在于以及由唱歌的男性所产生的参数值的范围内，除了B部分必须比任何自然的歌曲是最有效的。在Ch. dorsatus的祖先中，歌曲的两个元素可能是针对雌性（A部分）和雄性（B部分）的。
SummaryMales of the grasshopper Chorthippus dorsatus produce songphrases which contain two differently structured elements — pulsed syllables in the first part (A) and ongoing noise in the second part (B). Females of Ch. dorsatus answer to artificial song models only if both elements A and B are present. Females strongly prefer song models in which the order of elements is A preceding B. Females discriminate between the two elements mainly by the existence of gaps within A-syllables. Pulses of 5–8 ms separated by gaps of 8–15 ms make most effective A-syllables, while syllable duration and syllable intervals are less critical parameters. Females respond to models which contain more than 3 A-syllables with high probability. Female model preferences lie well in the range of parameter values produced by singing males, except for B-parts which must be longer than those of any natural song to be most effective. In ancestors of Ch. dorsatus the two elements of the songs might have been directed towards females (part A) and males (part B).
