Abstract
Aggregations of the common silverfish, 'Lepisma saccharina ' L., giant silverfish, 'Ctenolepisma longicaudata' (Escherich), and firebrat, 'Thermobia domestica' (Packard), are mediated by non-volatile, species-specific pheromones. In dual-choice olfactometer experiments, filter paper previously exposed to male, female, or juvenile 'L. saccharina' or 'C. longicaudata' arrested conspecifics regardless of developmental stage or gender. ' Lepisma saccharina' did not respond to the 'C. longicaudata ' pheromone, nor to the 'T. domestica' pheromone. However, ' C. longicaudata' responded to the pheromones of both 'L. saccharina ' and 'T. domestica', whereas 'T. domestica ' responded to the 'C. longicaudata' but not ' L. saccharina' pheromone. Female 'T. domestica' were significantly arrested by (i) loose, insect-derived debris brushed from shelters, (ii) a frass mixture manually separated from loose debris, and (iii) specific amber-type frass manually separated from the frass mixture, but did not respond to other types of shelter debris or insect-altered cellulose, suggesting that ' T. domestica' pheromone is present in amber-type frass. Keywords: 'Lepisma saccharina, Ctenolepisma longicaudata, Thermobia domestica,' Thysanura, Zygentoma, Lepismatidae, pheromone, aggregation, arrestment, frass, feces.
