Abstract：
Acoustic communication is widespread in beetles, is often sexually dimorphic, and plays a significant role in behaviours such as premating recognition, courtship, and copulation. However, the factors that determine the presence or absence of acoustic signalling in a given species remain unclear. We examined acoustic communication in bark beetles (Scolytinae) and pinhole borers (Platypodinae), which are two speciose groups with widespread sound production capabilities. We show that body size along with the sequence of host colonisation predict the presence of acoustic communication, and report, for the first time in the animal kingdom, a size limit-1.9 mm-below which acoustic signalling ceases to be present.
摘要：
声通信在甲虫中很普遍，通常是性二态的，并在诸如预先识别之类的行为中起着重要作用，求爱,和交配。然而,确定给定物种中是否存在声信号的因素尚不清楚。我们检查了树皮甲虫（Scolytinae）和针孔虫（Platypodinae）的声通信，这是两个特殊的集团，具有广泛的良好生产能力。我们表明，身体大小以及宿主定殖的顺序可以预测声通信的存在，和报告，第一次在动物王国,一个尺寸限制-1.9毫米-低于该限制，声学信号将不再存在。
