Alarm Pheromone in a Gregarious Poduromorph Collembolan (Collembola: Hypogastruridae) [PDF]

open access: yes, 2017
We report an alarm pheromone in the gregarious poduromorph collembolan, Hypogastrura pannosa. Cuticular rupture results in emission of a rapidly vaporizing hexane-soluble material with an active space diameter of ca. 1 cm.
