The transfer of fleas between the house mouse, Mus musculus, and the midday jird, Meriones meridianus, through social contacts was studied by performing interspecific dyadic encounters on a neutral arena. M. meridianus and M. musculus exchanged parasites through social contacts. The intensity of this exchange was higher between mice and adult male and young jirds than between mice and adult female jirds. The pattern of behavioural interactions was the main determinant of the intensity of flea exchange. Adult female jirds were highly aggressive towards mice. In contrast, interactions between male and young jirds and mice were mainly cohesive and resulted in higher frequency of flea transfer. The proportion of fleas transferred was positively correlated with the number and cumulative duration of tactile contacts between opponents in dyads.
通过在中性场地进行种间二元相遇实验，研究了家鼠（小家鼠）和子午沙鼠之间通过社交接触实现跳蚤转移的情况。子午沙鼠和小家鼠通过社交接触交换寄生虫。这种交换的强度在小鼠与成年雄性和幼年子午沙鼠之间比在小鼠与成年雌性子午沙鼠之间更高。行为互动模式是跳蚤交换强度的主要决定因素。成年雌性子午沙鼠对小鼠极具攻击性。相比之下，雄性和幼年子午沙鼠与小鼠之间的互动主要是有凝聚力的，且导致跳蚤转移频率更高。转移的跳蚤比例与二元组中对手之间触觉接触的数量和累积持续时间呈正相关。
