The host-parasite relationship, Tenebrio molitor-Hymenolepis diminuta, was analyzed. The learning behavior of infected and uninfected (control) beetles in a T-maze was compared. The infected beetles moved much slower in the T-maze than the controls. The infected beetles reached the same level of learning as the controls. However, they needed more trials than the controls. The effect of the infection was already distinct after the first week and even higher after the second week. This indicates that the initial phase of infection caused stress in the beetles. Longer infection did not worsen their ability to learn. Thus, the parasites clearly changed the behavior of their intermediate host and probably made them more susceptible to their final host, the rat.
分析了宿主-寄生虫关系，即黄粉虫-微小膜壳绦虫。比较了受感染和未受感染（对照）甲虫在T型迷宫中的学习行为。受感染的甲虫在T型迷宫中的移动速度比对照组慢得多。受感染的甲虫达到了与对照组相同的学习水平。然而，它们比对照组需要更多的试验。感染的影响在第一周后就已经很明显，在第二周后甚至更明显。这表明感染的初始阶段给甲虫带来了压力。更长时间的感染并没有使它们的学习能力恶化。因此，寄生虫明显改变了中间宿主的行为，可能使它们更容易被终末宿主大鼠感染。
