    Isolation and identification of allelochemicals that attract the larval parasitoid,Cotesia marginiventris (Cresson), to the microhabitat of one of its hosts (1991)

    Notes: Abstract Volatiles released from corn seedlings on which beet armyworm larvae were feeding were attractive to females of the parasitoid,Cotesia marginiventris (Cresson), in flight tunnel bioassays. Analyses of the collected volatiles revealed the consistent presence of 11 compounds in significant amounts. They were: (Z)-3-hexenal, (E)-2-hexenal, (Z)-3-hexen-1-ol, (Z)- 3-hexen-1-yl acetate, linalool, (3E)-4,8-dimethyl-1,3,7-nonatriene, indole, α-trans-bergamotene, (E)-β-farnesene, (E)-nerolidol, and (3E,7E)-4,8,12-trimethyl-1, 3,7,ll-tridecatetraene. A synthetic blend of all 11 compounds was slightly less attractive to parasitoid females than an equivalent natural blend. However, preflight experience with the synthetic blend instead of experience with a regular plant-host complex significantly improved the response to the synthetic blend. Our results suggest thatC. marginiventris females, in their search for hosts, use a blend of airborne semiochemicals emitted by plants on which their hosts feed. The response to a particular odor blend dramatically increases after a parasitoid experiences it in association with contacting host by-products.

    Field tests of syntheticManduca sexta sex pheromone (1994)
    Springer
    Journal of chemical ecology 20 (1994), S. 579-591

    ISSN: 1573-1561
    Keywords: Aldehydes ; formulation ; 10,12-hexadecadienal ; 10,12,14-hexadecatrienal ; moth ; Manduca sexta ; Lepidoptera ; Sphingidae ; tobacco hornworm ; trapping

    Notes: Abstract In field experiments traps were baited with live females or with a two-, four-, or eight-component blend of the 16-carbon aldehydes previously identified as components of the sex pheromone emitted by femaleManduca sexta moths. The blends were formulated on rubber septa. Traps baited with a blend of all eight aldehydes captured moreM. sexta males than any other treatment. Septa loaded with 600 μg of the eight-component blend were attractive to males for about seven days in the field. Septa loaded with the eight-component blend and stored in a refrigerator at 4°C for a year released the conjugated diene and triene aldehydes at the same rate as freshly prepared septa and were equally attractive in the field.

    Sex attractants for the white-barred groundling moth (Recurvaria leucatella clerck) and the lesser bud moth (R. nanella Hübner) (Lepidoptera: Gelechiidae) (1992)

    Notes: Abstract In field tests synthetic (3E,5Z)-3,5-tetradecadienyl acetate was found to attract large numbers of males ofRecurvaria leucatella Clerck into sticky traps. The other geometrical isomers did not influence catches. Of the corresponding monoenic compounds, (3E)-3-tetradecenyl acetate was highly attractive to a close relative,Recurvaria nanella Hübner. The catches of the latter species were suppressed by higher amounts of (5Z)-5-tetradecenyl acetate added to the bait, and the addition of (3E)-3-tetradecenol or (3Z)-3-tetradecenyl acetate was without effect. The attractive compounds can be used in traps for monitoring the two pests.

    Identification of a pheromone blend attractive to Manduca sexta (L.) males in a wind tunnel (1989)

    Notes: Analyses of solvent rinses of the external surfaces of pheromone glands excised from calling female tobacco hornworm moths, Manduca sexta (L.), revealed the presence of the following compounds: (Z)-9-hexadecenal, (Z)-11-hexadecenal, (E)-11-hexadecenal, hexadecanal, (E,Z)-10,12-hexadecadienal, (E,E)-10,12-hexadecadienal, (E,E,Z)-10,12,14-hexadecatrienal, (E,E,E,)-10,12,14-hexadecatrienal, (Z)-11-octadecenal, (Z)-13-octadecenal, octadecanal, and (Z,Z)-11,13-octadecadienal. The two trienals were identified by mass and PMR spectral analyses and by ozonolyses, and their structures were confirmed by synthesis. In a wind tunnel male tobacco hornworm moths exhibit the same behaviors in response to a synthetic blend of all of the components, the gland rinse, or a calling female. Both (E,Z)-10,12-hexadecadienal and (E,E,Z)-10,12,14-hexadecatrienal are required to stimulate males to complete the characteristic behavioral sequence: anemotaxis, approaching and touching the pheromone source, and bending their abdomens in apparent copulatory attempts. The other components of the blend may play more subtle roles.
