 Title    Xestia triangulum Hufn. and X. ditrapezium  
 Abstract    Electrophysiological analysis of male antennal Sensilla trichodea in Xestia triangulum and X. ditrapezium showed that they contain the same five types of receptor cells in both species. These cells responded specifically to the (Z)-alkenyl acetates Z7-12:Ac, Z5-14:Ac, Z7-14:Ac, Z9-14:Ac and Z 11-14:Ac. Yet, in field trapping tests, male X. trian­ gulum were highly attracted to pure Z5-14:Ac as a single compound, whereas male X. ditrapezium responded speci­ fically to a ternary combination of Z5-/ Z7-/ Z9-14: Ac with the Z7 isomer as the major constituent. The four other "key compounds" in X. triangulum, and the other two in X. ditrapezium, inhibited trap captures. The results are con­ sidered in view of the close taxonomic relationship of the two species and their potential reproductive isolation from other, pheromonally-related noctuid moths.
