Cerebral larvae of Dicorcoelium dendriticum and D. hospes and the brains of infected ants were studied. Morphologic differences of the freed larvae could not be found, but there were evident differences in number and localization of the cerebral stages. Ants infected with D. dendriticum usually showed one "Hirnwurm" while in the majority of the ants infected with D. hospes two larvae were found. The typical localization of the "Hirnwurm" of D. dendriticum was in the ventral part of the subesophageal ganglion; almost every larva of D. hospes was found in the dorsal part of an antennal lobe. The cyst walls of the larvae were visible only in some specimens. Their thickness seemed to depend on the localization of the larva. Differences in number and localization of the larvae, and hypotheticalmechanisms how they could influence the behavior of their hosts are discussed.
对枝双腔吸虫（Dicrocoelium dendriticum）和霍氏双腔吸虫（D. hospes）的脑内幼虫以及被感染蚂蚁的脑部进行了研究。未发现游离幼虫的形态学差异，但脑期幼虫在数量和定位上存在明显差异。感染枝双腔吸虫的蚂蚁通常有一条“脑蠕虫”，而在大多数感染霍氏双腔吸虫的蚂蚁中发现有两条幼虫。枝双腔吸虫“脑蠕虫”的典型定位在咽下神经节的腹侧部分；几乎每只霍氏双腔吸虫的幼虫都在触角叶的背侧部分被发现。幼虫的囊壁仅在一些标本中可见。其厚度似乎取决于幼虫的定位。讨论了幼虫在数量和定位上的差异以及它们可能影响宿主行为的假设机制。
