Ants, like other insects, have a heart that pumps hemolymph rhythmically. We designed an apparatus and procedure to non-destructively monitor the rate of cardiac contractions in ants, using a modified light microscope and infrared light. This allowed us to obtain the first baseline heart rate data on three ant species, collected in Georgia, USA. We next describe how ant heart rates can be stimulated, for comparing cardiac reactions among colonies, or for assessing stress responses. The procedures described here may be useful for other researchers interested in ant physiology.

如何测量蚂蚁的脉搏：一种无损监测蚁科基线和刺激心率的程序

蚂蚁和其他昆虫一样，有一颗有节奏地泵送血淋巴的心脏。我们设计了一种设备和程序，使用改进的光学显微镜和红外光来无损地监测蚂蚁的心脏收缩率。这使我们能够获得在美国乔治亚州收集的三种蚂蚁物种的第一个基线心率数据。我们接下来描述如何刺激蚂蚁心率，以比较群体之间的心脏反应，或评估压力反应。此处描述的程序可能对其他对蚂蚁生理学感兴趣的研究人员有用。
