[Learning in host foraging by the parasitoid Diadegma semiclausum (Hymenoptera : Ichneumonidae)]
Acta Entomologica Sinica 46 (6), 749-754
Abstract: Learning of host and host-plant recognition in the larval parasitoid Diadegma semiclausum Hellen (Hym. , Ichneumonidae) was studied. The results show that the host-plants fed on by host larvae of parasitoids during their immature stages did not affect host-plant preference of the ensuing female adults, but brief experiences by female parasitoids at early adult stages significantly affected their subsequent host preferences. Female parasitoids showed significant preferences for plant volatiles they had previously experienced. However, such preferences acquired through learning could be modified by new experiences. Female parasitoids could learn not only the volatile chemicals emitted by host-infested plants, but also the infochemicals emitted by host larvae.
