In this paper we report for the first time the identification of communication in castniid moths: Males mark three new compounds, namely n-octadecyl acetate, (Z)-9-octadecenyl acetate and (E,Z)- their territories and appear to bear all chemical burden. PLoS ONE 12(2): e0171166. doi:10.1371/ 2,13-octadecadienyl acetate, in males of the Castniid Palm Borer, Paysandisia archon, journal.pone.0171166 which could be involved in its short-range courtship behavior, and also shed light on recent Editor: Gadi V.P.
