将雌蛾（Psithyrus vestalis, Geoffroy in Fourcroy 1785）引入其自由觅食的寄主Bombus terrestris （Linnaeus 1758）中，研究了寄主和寄主在群落发育过程中的相互作用。在观察到的三个蜂群中，在寄生虫被引入后的6小时到6天内，发现了蜂后在巢中死亡。在其中两个蜂群中，寄主蜜蜂以雄性繁殖。所有的寄主巢都是由工蜂产下的卵孵化而成的，只有雄性出现。在这些情况下，与不产卵的工蜂相比，雌性蛇舌虫明显更喜欢与产卵工蜂接触。甚至在工蜂开始产卵之前，与第一组接触的数量就明显更高。这种寄生虫只在第三个蜂群中繁殖，而在第三个蜂群中，寄主没有成功地繁殖出年轻的蜂王或雄蜂。
Females of Psithyrus vestalis (Geoffroy in Fourcroy 1785) were introduced to free-foraging colonies of their host Bombus terrestris (Linnaeus 1758), and the interactions of parasite and host colony members during the development of the colony were studied. In three colonies observed, the B terrestris queens were found dead in their nests between six hours and six days after introduction of the parasite. In two of these colonies the host bees reproduced in males. As all host broods which were reared from eggs which had been laid by workers, only males emerged. In these cases, the Psithyrus females significantly favoured contacts to egg-laying workers, as compared to non-egg-laying workers. The number of contacts to the first group was significantly higher, even before the workers had started laying their eggs. The parasite only reproduced in the third colony, in which the host did not succeed in reproducing young queens or drones.
