Nasutitermes exitiosus

A diterpene hydrocarbon, assigned the trivial epithet nasutene, has been reported to be the trail pheromone of Nasutitermes exitiosus (27). This compound, which contains an unusual 14-membered ring structure, has been assigned the structure of neocembrene-A (I). Neocembrene can be derived from Cp CiA cyclization of geranylgeranyl pyrophosphate. 

Cembranoids are present both in plants and animals. The majority of the cembranoids of plant origin was isolated from tobacco. Cembranoid diterpenes, which serve as a trail pheromone and defense secretions, have been obtained from termites Nasutitermes exitiosus [160], Trinervitermes bettonianus [161], and various species of Cubitermes [162] and the ant Monmorium pharaonis [163],...
