 Title    Analysis o f a Sex-A ttractant System in the Noctuid M oth Rhyacia baja S ch iff  
 Abstract    Binary combinations o f (Z)-7-dodecenyl acetate and (Z)-9-tetradecenyl acetate in a 1/10 ratio were highly attractive to Rh. baja males in field trapping tests con­ ducted in southern Germany. Trap captures increased further on adding 0.1 or 0.3% o f (Z)-5-dodecenyl acetate to this lure; higher amounts o f this chem ical were strongly inhibitory, as were additions o f >3% o f (Z)-ll-h e x a -decenyl acetate. The trapping data are considered in terms o f electrophysiological responses o f five types o f antennal receptor cells.

 Title    Agrotis exclamationis  
 Abstract    The sex-attractant system of the dart moth Agrotis ex­ clamationis (L.) (Noctuidae) was re-investigated with elec-trophysiological and field trapping tests. The identified pheromone components (Z)-5-tetradecenyl acetate and (Z)-9-tetradecenyl acetate elicited maximum trap captures when combined in a Z5-/Z9-mixture ratio of between 100/10 and 100/20, in contrast to an earlier reported mixture opti­ mum of 100/5. Each compound activated a particular type of receptor cell located in the male antennal hair sensilla. Three further cell types discovered in these sensilla responded specifically to the non-pheromonal compounds (Z)-7-dodecenyl acetate and (Z)-7-and (Z)-l 1-tetra-decenyl acetate. These latter compounds did not show attractive or synergistic properties in field trapping tests but rather reduced captures when added to the binary pheromone blend as a third component. The biological functions of these three "attraction-inhibitors" remain unidentified.

 Title    The Pheromone Receptor System o f M ale Eulia ministrana L., with N otes on Other Cnephasiini M oths  
 Abstract    The antennal Sensilla trichodea o f male Eulia ministrana (Tortricidae: Cnephasiini) contain specialist receptor cells for the sex-attractant components (Z)-9-and (Z)-l 1-tetra-decenyl acetate and the attraction-inhibitors (E)-11 -tetra-decenyl acetate, (Z)-7-dodecenyl acetate, and (Z)-11 -hexa-decenyl acetate. The significance o f the latter two com ­ pounds as potential sex pheromone com ponents in Tortri­ cidae is considered.

 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.
