Abstract The sex-attractant system of the dart moth Agrotis exclamationis (L.) (Noctuidae) was re-investigated with electrophysiological 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 optimum 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)-11-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.

Traps baited with 100 μg (Z)-9-dodecenyl acetate and 10|ig (Z)-ll-tetradecenyl acetate are highly effective in attracting C. murinana males at varying population densities. The attractive mixture was established by electrophysiological and Field screening studies combined with chemical analysis of the female pheromone secretion. (Z)-9-dodecenyl acetate is a major constituent in washes of pheromone glands of calling C. murinana females. This compound, the first dodecenyl ester pheromone known for a species of the Archipini tribe, is moderately attractive on its own at low doses. Attraction is strongly synergized by 10% (Z)-11-tetradecenyl acetate but is inhibited by small amounts of (Z)-9- tetradecenyl acetate. Each of the three compounds acts upon a separate type of receptor cell in hair sensilla of the male antenna.

Abstract The principal component of the female sex pheromone of the European pine moth Dendrolimus pini L. (Lasiocampidae) was identified as (Z ,E)-5 ,7-dodecadienal by capillary gas chromatography, mass spectrometry, single receptor analyses, and field trapping tests. Traps initially baited with 1000 μg of (Z,E)-5,7-dodecadienal (>99%ZE) effectively monitored low D. pini populations over 6 weeks without rebaiting. Captures disappeared upon addition of ≧1% of either (E,Z)-5,7-dodecadienal or (Z,E)-5,7-dodecadienyl acetate, the key stimulants for additional receptor cell types located in male antennal hair sensilla.

The alkenyl acetates E9-12:Ac, Δ11-12:Ac and Zll-14:Ac were identified as minor components 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 Δ11 - 12 : Ac or Z11-14: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 E9-12: 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 E9-12:Ac strongly reduced captures. These inhibitory effects were more pronounced with attractant blends based on Δ11-14:Ac rather than Δ11-12:Ac. Each blend component activated its own type of antennal receptor cell.

Electrophysiological analysis of olfactory hair sensilla in male P. pisi has revealed four different types of presumed pheromone receptor cells, maximally responsive to (Z)-11-tetradecenyl acetate (Z11-14:Ac), (Z)-9-tetradecenyl acetate (Z9-14:Ac), (Z)-11-hexadecenyl acetate (Z11-14:Ac) 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 Z11-14: Ac/Z9-14: Ac in the ratio 100/100, whereas the 100/30 and 30/100 mixtures of the two compounds were only slightly attractive. No male P. pisi were captured by single chemicals or binary combinations of Z11-14: Ac/Z11-16: Ac, Z11-14:Ac/Z7-12:Ac, Z9-14:Ac/Z11-16:Ac, Z9-14:Ac/Z7-12:Ac, or Z11-16:Ac/Z7-12:Ac. Various compounds, including Z11-16: Ac and Z7-12:Ac, were tried as third chemicals in addi­tion to 100 μg Z11-14: Ac + 100 μg Z9-14: Ac but none increased trap catches over the basic lure.

Abstract Electrophysiological recordings from antennal hair sensilla of male P. flammea 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.

SUMMARY We performed a physiological and morphological characterization of sensilla auricillica in male Eriocrania semipurpurella moths. Each auricillic sensillum contained three olfactory receptor neurons. Responding neurons (87 of 139) could be grouped into five physiological types. Type 1 responded to(R,Z)-6-nonen-2-ol and type 2 to its enantiomer(S,Z)-6-nonen-2-ol, both of which are pheromone components of E. semipurpurella. Type 3 responded to both (R)-heptan-2-ol and(R,Z)-4-hepten-2-ol, which are pheromone components of the sympatric species E. cicatricella. Types 4 and 5 responded to the ketones(Z)-6-nonen-2-one and/or nonan-2-one, which are found in the pheromone glands of female E. semipurpurella. Field-trapping showed that type 3 receptor neurons mediate strongly antagonistic effects of (R)-heptan-2-ol and(R,Z)-4-hepten-2-ol on E. semipurpurella, while nonan-2-one should possibly be included as a synergist in the sex pheromone blend of this species. The attraction of E. cicatricella and E. sparrmannella to compounds mixed with the pheromone blend of E. semipurpurella shows that the pheromone components of E. semipurpurella have little or no antagonistic effects on these species. The morphology and physiology of eriocraniid pheromone sensilla are very similar to those found in the order Trichoptera (caddisflies), suggesting a homology between pheromone detection systems in the two sister orders Lepidoptera and Trichoptera.

Lures for a monitoring system based on sex attractant trapping of Agrotis segetum males were elaborated for Israel and Germany. Various mixtures of (Z)-5-aecenyl acetate, (Z)-7-dodecenyl acetate, (Z)-9-dodecenyl acetate, (Z)-9-tetradecenyl acetate, decyl acetate and dodecyl acetate were tested in 20 different blends. From comparison of all the trap catches a four-component lure consisting of (Z)-5-decenyl, (Z)-7-dodecenyl, (Z)-9-tetradecenyl and dodecyl acetate is recommended for monitoring of A. segetum in both countries.

In field trapping tests male Orthosia gothica (Lepidoptera: Noctuidae) were captured in traps baited with blends of (Z)-9-tetradecenyl acetate, (Z)-9-tetradecenol, (Z)-5-tetradecenyl acetate and (Z)-l 1-tetradecenyl acetate. The highest catches were recorded in traps baited with a 20:20:1:1 blend. The above quaternary blend is a potent sex attractant of this species, and it can be recommended in dosages of 10-100 μg per dispenser for monitoring purposes.

AbstractThe sex pheromone components of the black army cutworm, Actebia fennica (Tauscher), were identified in abdomen-tip extracts from calling female moths. The primary pheromone component was (Z)-7-dodecenyl acetate. Although (Z)-11-tetradecenyl acetate was detectable only in trace quantities in the extracts, it was the major component in the best synthetic blend for attraction of male moths. The most effective synthetic blend was (Z)-7-dodecenyl acetate and (Z)-11-tetradecenyl acetate at a ratio of 1:20. No other component detected in the extracts increased trap capture of males when added to the two-component blend; however, (Z)-5-dodecenyl acetate, (Z)-7-dodecenol, and (Z)-9-tetradecenyl acetate reduced catches. This two-component blend will be useful for studying the habits of the adults and for population monitoring.

Abstract Binary combinations of (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 conducted in southern Germany. Trap captures increased further on adding 0.1 or 0.3% of (Z)-5-dodecenyl acetate to this lure; higher amounts of this chemical were strongly inhibitory, as were additions of > 3% of (Z)-11-hexa-decenyl acetate. The trapping data are considered in terms of electrophysiological responses of five types of antennal receptor cells.
