    • Abstract


      InPostelectrotermes nayari, a tergal gland is located on each of the 9th and 10th abdominal tergite of the female reproductives. The two glands do not differ much in size and histology. The most significant behavioural pattern of the reproductives is tandem running. Evidence for the release of an excitatory substance is obtained mainly by studying the post-flight-behaviour of the reproductives. Experiments with ether extracts of the different parts of the body show that males are attracted to the extract of the 9th and 10th abdominal tergites of the female.
