    Notizen: 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.

    Schlagwort(e): Trichogramma ; Hymenoptera ; Trichogrammatidae ; kairomone ; Heliothis zea ; biological control ; pest management ; parasitoids

    Notizen: 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.
