 "Mycotypha microspora" is only detected by firebrats in the presence of cellulose, suggesting that metabolites of the enzymatic cellulose digestion by "M. microspora" (such as D-glucose) serve as the aggregation/arrestment cue.A follow-up study showed that gray silverfish, "Ctenolepisma longicaudata", also respond with arrestment to "Mycotypha microspora", but not so the common silverfish "Lepisma saccharina".Furthermore, direct current-powered low-level electromagnetic coils with static electromagnetic fields were found to induce attraction or arrestment behaviour in "Lepisma saccharina" and "Thermobia domestica".
