    Description / Table of Contents: Résumé L'examen en olfactomètre a porté sur les réactions face à d'autres femelles de la même espèce, de femelles vierges ou ayant copulé d'Heliothis armigera Hübner et H. zea Boddie. Le lot comprenait 8 femelles, vierges ou ayant copulé en présence d'une femelle vierge ou ayant copulé. Les 4 combinaisons possibles de femelles vierges et de femelles ayant copulé ont été examinées avec 12 répétitions pour chaque espèce. Un extrait de l'extrémité de l'abdomen de femelles vierges d'une espèce a été présenté aux femelles de l'autre espèce pour examiner les possibilités de réactions interspécifiques aux phéromones. Pour chaque espèce, les réactions interspécifiques de répulsion entre femelles ont été hautement significatives par rapport aux témoins, à l'exception toutefois des réactions de femelle ayant copulé face à des femelles ayant elles aussi copulé. Les répulsions moyennes chez H. armigera et H. zea pour les 8 femelles de chaque expérience ont été: a) vierges en présence d'une vierge: 7,33 et 7,66; b) vierges en présence d'une femelles ayant copulé: 5,76 et 5,58; c) femelles ayant copulé en présence d'une vierge: 4,67 et 4,83. Les différences sont hautement significatives entre chaque paire de moyennes et entre chaque paire et le lot témoin; 3,17; 3,17; 3,42; 4,00 pour H. armigera; 3,17; 3,50; 2,83 et 3,75 pour H. zea. Les femelles vierges des deux espèces, H. armigera et H. zea ont présenté une réaction de répulsion en présence d'un extrait de l'abdomen de l'autre espèce; les répulsions moyennes étant respectivement 5,53 et 5,33 contre 3,83 et 3,58 pour le lot trémoin. On peut en conclure que ces répulsions doivent entraîner une tendance à la répartition uniforme.
    Notes: Abstract An olfactometer was used to determine the effect of pheromones released by females of the bollworms Heliothis armigera (Hübner) and H. zea (Boddie) on females of the same species. Four combinations of virgin and mated females were tested for repellency of one to the other. Evidence is presented that females of the two bollworms were repelled by females of the same species. In addition, extracts of virgin female abdomens of each species repelled virgin females of the other species.

    Sex attractant for three species of the genusOncocnemis: O. chandleri (Grt.),O. cibalis (Grt.), andO. mackiei (B. & Benj.) (Lepidoptera: Noctuidae) (1984)

    Notes: Abstract Oncocnemis chandleri, O. cibalis, andO. mackiei were attracted to chemically baited traps in the field. In all three cases, (5E,7Z)-dodecadienyl acetate was a key component for attraction. Attraction ofO. chandleri to traps baited with the (5E,7Z)-dodecadienyl acetate was inhibited by addition of (Z)-7-dodecenyl acetate.O. cibalis required both (5E,7Z)-dodecadienyl acetate and (Z)-7-dodecenyl acetate for attraction. Electroantennogram responses for the three species are also reported.

    Sex pheromone of a conifer-feeding budworm,Choristoneura retiniana, Walsingham (1984)

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Sex pheromone components collected from femaleChristoneura retiniana included 11-tetradecenyl acetates and alcohols. The major component wasE-11-tetradecenyl acetate (E11–14∶Ac) with a lesser amount ofZ isomer necessary to induce male response. A 92∶8 ratio ofE,Z11–14∶ Ac appeared optimal. The alcohol component was present at about 10% of the total pheromone mixture, and traps baited with acetates plus alcohol surpassed unmated females in their degree of attractiveness. Chemical analysis indicated a 9∶:1 ratio of theE — Z isomers of 11-tetradecenyl alcohol (11–14∶ol) pheromone components, although bait formulations containing a predominance of either theE orZ isomers were equally successful in field bioassays. Based on male response to traps,E- andZ11–14∶Ac (92∶8E — Z) are essential pheromone components for long-range sex attraction. The 11–14∶ ol enhanced attraction when added at 10% of the total pheromone blend.

    Notes: Abstract (Z,Z,Z,E)-3,6,9,11-Nonadecatetraene and (Z,Z,Z,Z)-3,6,9,11-nonadecatetraene, sex pheromone components ofAlsophila pometaria, were synthesized by stereoselective Wittig reactions and found to be spectroscopically and chromatographically identical to isolated natural material. Flight-tunnel bioassays and field-trapping experiments confirmed that the two tetraenes together with (Z,Z,Z)-3,6,9-nonadecatriene are sex pheromone components. While traps baited with either tetraene individually captured conspecific males in field-trapping experiments, addition of the triene, which captured no males by itself, to either tetraene resulted in synergistic responses.

    Attraction and inhibition in moth species responding to sex-attractant lures containing Z-11-hexadecen-1-yl acetate (1977)

    Notes: Abstract Sex attractants for several sympatric noctuid moths required Z-11-hexadecen-1-yl acetate and additional olefinic compounds (coattractants) for effective, species-specific operation. In nearly all cases at least one of the coattractant compounds for each species functioned as a strong inhibitor of one or more of the other species in the group. It was concluded that species specificity in sex attractants can be achieved through conspecific coattractants which are at the same time transspecific inhibitors.

    Notes: Abstract 90% (Z)-11-tetradecen-1-yl acetate, 5% (Z)-9-tetradecen-1-yl acetate, 5% (Z)-11-tetradecen-1-ol, dodecyl acetate (〈1%), and tetradecyl acetate (〈1%) were identified from gland extracts ofPandemis heparana females by gas chromatography and gas chromatography-mass spectrometry analysis (including mass fragmentography studies), chemical characterization, total synthesis, laboratory and field bioassays. In the field, a mixture of (Z)-11-tetradecen-l-yl acetate and (Z)-9-tetradecen-l-yl acetate (95∶5) was found to be essential for attractiveness ofP. heparana males.

    Notes: Abstract In addition to three known sex lure components [(Z)-11-hexadecenyl acetate, (Z)-11-hexadecenal, and (Z)-11-hexadecenol], (Z)-9-tetradecenyl acetate was field-proven as a trace coattractant for malePlutella xylostella, with an optimal content below 0.01% in blends. This potent four-component lure for diamondback males also attractedCrymodes devastator males, and in this respect is not different in its attractancy from virgin diamondback females. Replacement of (Z)-9-tetradecenyl acetate in the four component lure with (Z)-9-tetradecen-1-ol, at the level of 10% of the total lure mixture, did not alter its attractancy for diamondback males, but it did inhibit attraction ofCrymodes devastator. The status of biologically active components as possible sex pheromones or para-pheromones is discussed.

    Notes: Abstract E∶Z blends of (E)-11-tetradecenal were field tested (three experiments) for their attractiveness to male spruce budworm,Choristoneura fumiferana (Clemens), moths in northern Maine. Blends of 92.5–99%E isomer caught the most moths (three experiments); blend 95%E had the highest cumulative catch throughout two experiments. Rates of catch per hour for the four most attractive blends (92.5–99%E) showed highly variable responses among experiments; however, similarities were noted for rates of catch within the same experiment. For all experiments and observation hours, blend 95%E had the highest mean rate of catch.

    Notes: Abstract FemaleChilo partellus (Swinhoe) abdominal tip extracts were examined by gas-liquid chromatography (GLC) combined with simultaneous electroantennographic (EAG) recording from the male moth. Two olfactory stimulants were detected and identified as (Z)-11-hexadecenal (I) and (Z)-11-hexadecen-1-ol (II) by their GLC behavior, microchemical reactions, and comparison with synthetic materials. Both compounds were detected in volatiles emitted by the “calling” female moth. Synthetic (Z)-9-tetradecenyl formate, a structural analog of aldehyde (I), also elicited a significant EAG response from the male moth. Field trials carried out in India using synthetic (I) and (II) as bait in water traps showed that compound (I) was highly attractive to maleC. partellus; compound (II) was not attractive, and its addition to (I) significantly reduced trap catches.

    Notes: Abstract Field tests utilizing crude pheromone extracts fromRhyacionia frustrana, R. rigidana, R. subtropica, andR. buoliana showed thatR. subtropica andR. buoliana were mutually attractive.R. frustrana was attracted in low numbers to bothR. subtropica andR. buoliana, butR. subtropica andR. buoliana did not significantly respond toR. frustrana. R. rigidana did not respond to pheromone extracts from any otherRhyacionia spp., nor was it attractive to the others. Cross-attraction occurred among those species which were largely allopatric and shared few tree hosts.
