Data for: Expression of trematode-induced zombie-ant behavior is strongly associated with temperature

Parasite-induced modification of host behavior increasing transmission to a next host is a common phenomenon. However, field-based studies are rare and the role of environmental factors in eliciting host behavioral modification is often not considered. We examined the effects of temperature, relative humidity (RH), time of day, date, and an irradiation-proxy on behavioral modification of the ant Formica polyctena (Förster, 1850) by the brain-encysting lancet liver fluke Dicrocoelium dendriticum (Rudolphi, 1819). This fluke induces ants to climb, and bite to vegetation by the mandibles in a state of temporary tetany. A total of 1,264 individual ants expressing the modified behavior were observed over 13 non-consecutive days during one year in the Bidstrup Forests, Denmark. A sub-set of those ants (N=172) was individually marked to track attachment and release of infected ants in relation to variation in temperature.寄生虫诱导宿主行为改变以提升向后续宿主的传播效率，是一类较为普遍的现象。然而，相关野外实地研究仍较为匮乏，且环境因素在诱导宿主行为改变过程中的作用常被忽略。本研究探究了温度、相对湿度（Relative Humidity, RH）、日间时段、日期以及辐射替代指标，对寄生于脑部的矛形双腔吸虫（*Dicrocoelium dendriticum*，Rudolphi, 1819）诱导林地蚁（*Formica polyctena*，Förster, 1850）发生行为改变的影响。该吸虫可诱导受感染蚂蚁攀爬至植被上方，并以颚部紧咬植被，进入暂时性强直状态。本研究于丹麦比兹楚普森林（Bidstrup Forests）开展，周期为一年，在13个非连续观测日中共记录到1264只表现出该行为改变的受感染蚂蚁。研究选取其中172只蚂蚁（N=172）进行个体标记，以追踪受感染蚂蚁的附着与释放行为与温度变化的相关性。
