    Notizen: Abstract Ethyl nicotinate was found to be a potent attractant forThrips obscuratus in peaches and apricots. The male-to-female ratio in traps was 1∶8. The chemical was more attractive than ripe fruit, with peak catches at harvest. Season-long trapping showed the efficiency of the chemical compared to unbaited traps. The chemical remained attractive for at least 2 weeks when 50 μl were placed in open 2-ml vial caps. Various pyralids, geometrids (Lepidoptera), and chironomids (Diptera) were also attracted in low numbers to ethyl nicotinate.

    Use of the64Ni(36S,34,35Si)66,65Zn reactions to measure the masses of34Si and35Si (1986)
    Springer
    The European physical journal 324 (1986), S. 283-287

    Thema: Physik
    Notizen: Abstract The ground-state masses of35Si and34Si have been measured using the reactions64Ni(36S,35,34Si)65,66Zn at a36S beam energy of 198 MeV.34,35Si14+ ions were analysed and identified in a QMG/2 magnetic spectrometer and gas-filled focal-plane detector. The experimental mass excess of35Si was determined to be −14.58± 0.12 0.07 MeV while that of34Si was measured as −19.961±0.034 MeV. A comparison is made with the results of mass model predictions.

    Attraction and repulsion of the aphid,Cavariella aegopodii, by Plant Odors (1981)
    Springer
    Journal of chemical ecology 7 (1981), S. 881-888 
    Details
    ISSN: 1573-1561
    Schlagwort(e): Aphid ; Cavariella aegopodii ; Homoptera ; Aphididae ; plant odor ; carvone ; attractant ; repellent ; host-finding
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie , Chemie und Pharmazie
    Notizen: Abstract Cavariella aegopodii is induced to land on traps by the monoterpene carvone, and the relevance of this to host-finding by the aphid is discussed. Catches are reduced by linalool. The interaction of plant chemicals in natural communities is discussed, and the possibility of using repellent chemicals for crop protection is suggested.
