The rapid mandible strike of a termite soldier
Arthropods use a remarkable variety of mechanisms to store energy for rapid ballistic movements [1-8]. These movements are primarily either for prey capture [1,2] or for predator evasion [3-5], although the mandible strike of the trap-jaw ant can produce both outcomes [6,7]. Soldiers of the termite Termes panamaensis (Snyder) also have a mandible strike [9]. We report that this mandible strike ...
متن کاملSoldier formation regulated by a primer pheromone from the soldier frontal gland in a higher termite, Nasutitermes lujae.
In the nasute higher termite Nasutitermes lujae, the differentiation of new soldiers is suppressed or delayed by the soldiers themselves. Experimental data strongly suggest that this inhibitory effect results from the action of a primer pheromone secreted by the frontal gland of soldiers. The pheromone must be contacted directly. Thus, the frontal gland of termite soldiers assumes a new role in...
متن کاملSoldier morphogenesis in the damp-wood termite is regulated by the insulin signaling pathway.
Eusocial insects exhibit various morphological castes associated with the division of labor within a colony. Termite soldiers possess defensive traits including mandibles that are greatly exaggerated and enlarged, as compared to termite reproductives and workers. The enlarged mandibles of soldiers are known to result from dynamic morphogenesis during soldier differentiation that can be induced ...
متن کاملTyraminergic and Octopaminergic Modulation of Defensive Behavior in Termite Soldier
In termites, i.e. a major group of eusocial insects, the soldier caste exhibits specific morphological characteristics and extremely high aggression against predators. Although the genomic background is identical to the other non-aggressive castes, they acquire the soldier-specific behavioral character during the course of caste differentiation. The high aggressiveness and defensive behavior is...
متن کاملDopamine regulates termite soldier differentiation through trophallactic behaviours
Caste polyphenism in social insects is regulated by social interactions among colony members. Trophallaxis is one of the most frequently observed interactions, but no studies have been conducted identifying the intrinsic factors involved in this behaviour and caste differentiation. Dopamine (DA) has multiple roles in the modulation of behaviours and physiology, and it produces species-specific ...
