 Title    Wolfgang Altenkirch  
 Abstract    Electrophysiological recordings from antennal hair sensilla of male P. flam m ea revealed two types (A, B) of presumed pheromone receptor cells. The A receptors responded max­ imally to (Z)-9-tetradecenyl acetate and the B cells to (Z)-11-tetradecenyl acetate. In the field, a 100:5 mixture of the two compounds attracted 10 times more males than the (Z) -9 isomer alone.

 Title    des Zw ergw elses Ictalurus nebulosus mit Procionfarbstoffen Selective Staining by Procion Dyes o f Olfactory Sensory Neurons in the Catfish Ictalurus nebulosus  
 Abstract    Procion Brilliant Yellow M 4R AN and Procion Yellow M 4R applied to the catfish olfactory mucosa stain intra-vitally and enter the olfactory receptors by their dendrites. The dye invades the receptor pericaryon and subsequently migrates within the axon in distal direction. Fluorescence microscopy of aldehyd fixed and paraffin sectioned prepa­ rations reveals clear selective staining o f the sensory neu­ rons in yellow colour.

 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    Sensory Efficacy of Alkyl-Branched Pheromone Analogues in Noctuid and Tortricid Lepidoptera  
 Abstract    The effect of introducing alkyl substituents (methyl to pentyl) to the chain segment n in long-chain alkenyl acetates, CH3(CH2)nCH = CH(CH2) O T -0-C0CH3 (I), was investigated in pheromone receptors of Noctuidae, Tortricidae, and Cochylidae species. The receptor types studied were maximally responsive to (Z)-7-or (Z)-9-dodecen-l-yl acetate, (Z)-l-, (Z)-9-, or (Z)-11-tetradecen-1-yl acetate, or (Z)-11-hexadecen-l-yl acetate, representing key compounds with re = l, n = 3, or n = 5 methylene groups. In terms of the relative stimulus amounts required to elicit equivalent EAG amplitudes, the efficacy of the alkyl-branched derivatives was between 1/1000 to 300 times that of the unbranched chain of the same length and double bond position. The effects of branching were specific to the type of receptor, the length and double bond position of the parent chain, and the kind and position of the alkyl substituent. The most pronounced increase observed occurred with receptors for « = 1 type pheromones, (Z)-9-dodecen-l-yl acetate and (Z) -11-tetradecen-l-yl acetate when an a-methyl group was introduced to elongated derivatives; whereas the greatest decreasing effects were obtained on receptors for the n = 5 type compound, (Z)-7-tetradecen-l-yl acetate. The results show basic differences in structure-response relationships between the Noctuidae vs Tortricidae receptors studied. Various possible effects of the substituent groups during sensory transduction are considered. The data should contribute to further elucidation of interaction mechanisms of unbranched alkenyl acetate pheromones (I) with insect olfactory receptors.

 Title    A Sex Attractant for the Green Budworm Moth, Hedya nubiferana  
 Abstract    The two major components o f the female pheromone blend of H edya nubiferana have been identified as (E, £)-8,10-dodecadienyl acetate and (Z)-8-dodecenyl acetate. Each compound acts on a specialist receptor type in olfactory hair sensilla of the male antenna. In field screening tests, combinations of the two compounds and dodecanyl acetate were highly attractive to H. nubiferana males. The (Z, £)-8,10 isomer attracted males of H edya ochroleucana.

 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.

 Title    Sex Attractant System in Polia pisi L. (Lepidoptera: Noctuidae)  
 Abstract    Electrophysiological analysis o f olfactory h air sensilla in male P. pisi has revealed four different types o f presum ed pherom one receptor cells, maximally responsive to (Z)-ll-tetradecenyl acetate (Z ll-1 4 :A c), (Z)-9-tetradecenyl acetate (Z 9-14:A c), (Z)-l 1-hexadecenyl acetate (Z ll-1 4 :A c) and (Z)-7-dodecenyl acetate (Z7-12: Ac), respectively. These four compounds were tested, singly and in various combinations, for efficacy in attracting P. pisi males in the field. High trap catches were obtained with mixtures of Z ll-1 4 :A c /Z 9 -1 4 :A c in the ratio 100/100, whereas the 100/30 and 30/100 mixtures o f the two compounds were only slightly attractive. N o male P. pisi were captured by single chemicals or binary combinations o f Z ll-1 4 :A c /Z ll-1 6 :A c , Z ll-1 4 :A c /Z 7 -1 2 :A c , Z 9 -1 4 :A c /Z l 1-16:Ac, Z 9 -1 4 :A c/Z 7 -1 2 :A c, or Z 1 1-16:A c/Z 7-12:A c. Various compounds, including Z 1 1-16:Ac and Z7-12:A c, were tried as third chemicals in ad d i­ tion to 100 ng Z 1 1-14: Ac + 100 ng Z 9-14: Ac but none increased trap catches over the basic lure.

 Title    The Sex Pheromone of the Silver Y Moth Chrysodeixis eriosoma (Doubleday) in New Zealand on leave at the En­ tomology D ivision  
 Abstract    An investigation o f the sex pherom one o f the N ew Zealand Silver Y Moth Chrysodeixis erio­ soma (Doubleday), formerly described as Plusia chalcites (Esper) resulted in the identification o f the major active components as 7Z-and 9Z-dodecenyl acetates, in approx. 97:3 ratio. This blend was attractive to C. eriosoma m ales in the field and in a laboratory flight tunnel. 5Z-D odecenyl acetate and 7Z-dodecenyl alcohol inhibited this response in the field. C. eriosoma was also attract­ ed to the 5:1 blend o f 7Z-dodecenyl acetate and 9Z-tetradecenyl acetate reported as the phero­ mone o f Chrysodeixis (Plusia) chalcites in the western Palaearctic. Specialist receptor cells for all 5 compounds mentioned were found in m ale antennal sensilla in both species.

 Title    Secondary Sex Pheromone Components of Choristoneura murinana Hb. (Lepidoptera: Tortricidae)  
 Abstract    The alkenyl acetates £9-12:Ac, zlll-12:Ac and Zll-14:Ac were identified as minor compo-nents of the C. murinana female pheromone blend by chemical analyses of volatile pheromone gland constituents and potential pheromone precursors, electrophysiological recordings from single receptor cells, and field trapping tests. Gland washes from virgin females contained these compounds at 3%, 10% and 5%. respectively, the amount of the primary pheromone component Z9-12:Ac already reported. A 0.3% addition of either Jll-12:Ac or Zll-14:Ac significantly raised trap captures over Z9-12:Ac alone and a 3-30% addition of either minor component revealed maximum captures, not increased further by including both synergists within the same blend. A functional role of the £9-12: Ac could not be established during this study; 3% of it when combined with the pheromonal ratio mixture of the three other components tended to increase trap captures further whereas in various other mixture combinations the £9-12:Ac strongly reduced captures. These inhibitory effects were more pronounced with attractant blends based on Zll-14:Ac rather than Zlll-12:Ac. Each blend component activated its own type of antennal receptor cell.
