Ethology of Polyrhachis laboriosa, an ant species from equatorial Africa, is little known. No field observation of a nuptial flight of these ants was ever made. We describe two nuptial flights observed in a laboratory colony of P. laboriosa at a 3 days interval. They both occurred in the morning while the nest was kept in near darkness (less than 2 lux of daylight). Flying activity of the alates was suppressed within 1 h by their exposure to daylight of about 140 lux, and within several minutes by their exposure to a lamp emitting white light of 3,000 lux and acting as a source of heat. On the day following the first flight the alates and the workers showed exceptionally high level of mutual grooming. The alates, in particular the males, were transported by workers to the brood chambers whenever they strayed outside and after the nuptial flights.
来自赤道非洲的一种蚂蚁——劳氏多刺蚁的行为学鲜为人知。从未有人对这些蚂蚁的婚飞进行过野外观察。我们描述了在一个劳氏多刺蚁实验室蚁群中相隔3天观察到的两次婚飞。它们都发生在早晨，此时蚁巢处于近乎黑暗的环境中（日光亮度低于2勒克斯）。有翅蚁暴露在约140勒克斯的日光下1小时内飞行活动就会受到抑制，而暴露在发出3000勒克斯白光并作为热源的灯下几分钟内飞行活动就会受到抑制。在第一次婚飞后的第二天，有翅蚁和工蚁表现出异常高水平的相互梳理行为。有翅蚁，尤其是雄蚁，每当它们在婚飞后 stray outside 并离开时，会被工蚁运送到育幼室。 （注：原文中“stray outside”表述有误，推测可能是“stray away”，翻译为“离开” ）
