    Rotational bands in 167Hf (1999)

    Notes: Abstract: High-spin states in 167Hf, populated in the 141Pr(30Si, p3n)167Hf reaction, have been studied using the nordball Ge detector array. Three rotational cascades have been observed for the first time and the previously-known level scheme has been extended to significantly higher spin. Band-crossing effects are discussed within the framework of Woods-Saxon cranking calculations and are found to be in good agreement.

    Notes: 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.

    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
    Keywords: Aphid ; Cavariella aegopodii ; Homoptera ; Aphididae ; plant odor ; carvone ; attractant ; repellent ; host-finding
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: 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.
