Three adult cave-dwelling ground beetle species were induced to
discharge secretions of their pygidial glands into vials.
Dichloromethane extraction was used to obtain the secretions. In total,
42 compounds were identified by GC/MS analysis. Pheggomisetes ninae
contained 32 glandular compounds, Laemostenus (Pristonychus) punctatus
13, whereas Duvalius (Paraduvalius) milutini had nine compounds.
Caproic, oleic, palmitic, and stearic acids were present in the samples
of all analyzed species. Undecane was predominant in the extract of L.
punctatus. Palmitic acid was the major component in the secretion of D.
milutini. Finally, the most abundant compounds in P. ninae secretion
were heptacosene and nonacosadienes. Herein, we present the first data
on the identification of pygidial gland secretion components in both
troglophilous and troglobite cave-dwelling ground beetles. Some
compounds are reported for the first time in the secretions of ground
beetles and other higher or lower taxa. The adaptation to underground
life has not led to a reduction or changes in the chemical defense
mechanism in the analyzed troglophilous and troglobitic Platyninae and
Trechinae taxa.
