 Title    Enzymatic Conversion of Sex Pheromones in Olfactory Hairs of the Male Silkworm Moth Antheraea polyphemus  
 Abstract    The sex pheromone compound [6,7-3H]-6,ll-hexadecadienyl acetate is enzymatically converted to its corresponding fatty alcohol, aldehyde and acid in living and homogenized olfactory hairs and in other parts of the antennae of the male silk-moth Antheraea polyphemus. The pheromone is metabolized in vitro mainly in the inner hydrophilic compartments, but scarcely in the outer hydrophobic cuticle of the olfactory hairs.

 Title    Sex Attractant of the Rosy Russian Gypsy Moth (Lymantria mathura Moore)  
 Abstract    We report identification of the sex attractant of the rosy Russian gypsy moth, Lymantria m athura Moore. Two compounds, Z,Z,Z-3,6,9-nonadecatriene 1 and its monoepoxide Z,Z-(95,10/?)-9,10-epoxy-3,6-nonadecadiene 4a, have been identified from abdominal tip ex­ tracts of female moths based on coupled gas chromatography/electroantennogram detector responses and dose response curves. Single cell recordings showed that only one of the mo­ noepoxide enantiomers (S,R) was active. In field tests, both the (5,/?)-monoepoxide and the racemate were active. This type of pheromone system, unusual for a Lymantriid, is more typical of those found in the families Arctiidae, Noctuidae and Geometridae.

 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    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.

 Abstract    5,9-Dimethylheptadecane and 5,9-dimethylpentadecane represent major components of the sex pheromones of fe-males of the leafminer moths Leucoptera scitella and Peri-leucoptera coffeella respectively; 5,9-dimethylhexadecane was found in both species as a minor component. These branched chiral hydrocarbons represent a new type of Lepidopteran pheromones, for which simple syntheses are described.

 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    Phyllonorycter sylvella Moths  
 Abstract    The SPM E (solid phase micro extraction) technique was used in the collection of volatiles released by calling females of the 4 -6 mm long tentiform leafminer moth Phyllonorycter sylvella (Lepidoptera, Gracillariidae). The volatiles released by the calling P. sylvella females were identified by GC-M S as a mixture of Z10-tetradecenyl acetate (9 2 %), £10-tetrad ecen yl acetate (2 %) and Z 8 -tetradecenyl acetate (6 %). The amount of volatiles released by one calling female during three hours and collected on a polydimethylsiloxane fibre, was as large as the amount extracted from the glands of 20 females. The SPM E technique gives the oppor­ tunity of continuously following the release of behaviour mediated signals from weak scented living organisms.
