Data on the effects of deltamethrin and fipronil on black-tailed prairie dog ectoparasites, South Dakota, USA, 2018-2019

Data were collected to investigate effects of deltamethrin and fipronil on ectoparasites from black-tailed prairie dogs in South Dakota, USA. In late-July 2018, we treated 3 sites with 0.05 percent deltamethrin dust and 5 sites with host-fed 0.005 percent fipronil grain. Three non-treated sites functioned as experimental baselines. We collected ectoparasites before treatments (June-July 2018) and after treatments (August-October 2018, June-July 2019). We combed ectoparasites from live-trapped, anesthetized prairie dogs. Trapping on treated and non-treated sites occurred simultaneously or nearly simultaneously in each year. Detected ectoparasites were counted and placed back on the prairie dogs from which they were collected to reduce a removal effect. Ectoparasites included fleas, lice, and mites.

本数据集采集自美国南达科他州的野外实验，旨在探究溴氰菊酯（deltamethrin）与氟虫腈（fipronil）对黑尾土拨鼠体表体外寄生虫（ectoparasites）的影响。2018年7月下旬，我们对3个样地施加0.05%溴氰菊酯粉剂，对5个样地投喂含0.005%氟虫腈的谷物饵料供宿主黑尾土拨鼠摄食；另设3个未施加任何处理的样地作为实验对照基线。我们分别在处理前（2018年6-7月）与处理后（2018年8-10月、2019年6-7月）采集体外寄生虫：通过梳检操作，从经活体捕捉并麻醉的黑尾土拨鼠体表获取寄生虫。每年均在处理组与对照组样地同步或近乎同步开展捕捉工作。对检出的体外寄生虫完成计数后，将其放回至原宿主黑尾土拨鼠体表，以降低移除寄生虫操作对实验结果造成的干扰效应。本次采集的体外寄生虫涵盖跳蚤、虱类与螨类。
