摘要: 研究了半闭弯尾姬蜂寄主搜索过程中的学习行为。结果表明,成虫期之前的饲养寄主所取食的寄主植物对成蜂行为没有影响,而雌蜂早期的短暂经历可对其随后的行为反应产生显著影响,从而对已经历的植物气味表现出显著的嗜好,但这种通过学习所表现出的嗜好又可因新的经历而改变。雌成蜂不仅能对其所经历的虫伤寄主植物释放的信息化合物进行学习,而且对其所经历的寄主幼虫的信息化合物也能进行学习。

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.
