    Kairomones and their use for management of entomophagous insects (1981)

    Notes: Abstract Trichogramma pretiosum Riley females exhibit success-motivated searching after oviposition. The stimulatory effect of contact with host eggs makes host-egg density an important factor in determining the appropriate strategy for behavioral manipulation, using kairomones, that simulate host seeking, in biological control programs. Host eggs can be used, in conjunction with kairomones or by themselves, to improve the performance of these important beneficial insects.

    Anti-Pr cold agglutinins recognize immunodominant α2,3- or α2,6-sialyl groups on glycophorins (1995)
    Springer
    Glycoconjugate journal 12 (1995), S. 714-720 
    Details
    ISSN: 1573-4986
    Keywords: Anti-Pr cold agglutinins ; sialidase ; sialyltransferase

    Topics: Chemistry and Pharmacology
    Notes: Abstract Anti-Pr cold agglutinins (CAs) with the subspecificities anti-Pr1h,-Pr1d, -Pr2, -Pr3h, -Pr3d, -PrM and anti-Sa CAs recognize immunodominantN-acetylneuraminic acid (NeuN Ac) groups of tetra and/or trisaccharides (O-glycans) of glycophorin. These O-glycans are sialylated in α2,3- and/or α2,6-linkages. Sa and most Pr antigens have been inactivated by α2,3-specific sialidases. Antigenicity was reconstituted on desialylated glycophorin by α2,3-specific Galβ1,3GalN Ac-sialyltransferase indicating that α2,3-linked NeuN Ac groups are the immunodominant components of Sa and most Pr antigens. Some Pr antigens were resistant to α2,3-specific sialidase and were not reconstituted by α2,3-specific Galβ1,3GalN Ac-sialyltransferase, which indicates that α2,6-linked NeuN Ac group represents an immunodominant component of some Pr antigens.

    Kairomones and their use for management of entomophagous insects (1979)
    Springer
    Journal of chemical ecology 5 (1979), S. 673-680 
    Details
    ISSN: 1573-1561
    Keywords: Trichogramma ; Hymenoptera ; Trichogrammatidae ; kairomone ; Heliothis zea ; biological control ; pest management ; parasitoids
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract A kairomone from adultHeliothis zea (Boddie) scales is an important factor in the host selection process ofTrichogrammapretiosum Riley. If the host density is sufficiently high (i.e., 1 egg/500 cm2) and higher), a complete coverage or solid treatment of kairomone spray may be the optimum for increasing parasitization rates, but this is not the case at lower host densities (e.g., 1 egg/2000 cm2). At the lower densities, the kairomone must be distributed in such a way as to retain the parasitoids in the target area without inhibiting their movement from one ovi-position site to the next. Simulated moth scale particles appear to fill this need since their density can be regulated to provide the optimum frequency of parasitoid stimulation and thus maximum rates of parasitization at prevailing host densities.
