Data on the efficacy of deltamethrin flea control with small rodents on prairie dog colonies in Montana and Utah, 2001-2004

Data on the efficacy of deltamethrin flea control with small rodents on prairie dog colonies in Montana and Utah, 2001-2004. Data were collected on 12 colonies of 3 prairie dog (PD) species at 5 sites in Montana and Utah. PD species included black-tailed PDs (Cynomys ludovicianus, BTPDs), Utah PDs (C. parvidens, UPDs), and white-tailed PDs (C. leucurus, WTPDs). Sample sizes from 6 small rodents (Species in the data file) were sufficient for analysis: deer mice, grasshopper mice, Ord's kangaroo rats, hispid pocket mice, dark kangaroo mice, and sagebrush voles. Efficacy of deltamethrin was assessed by combing fleas from live-trapped, anesthetized rodents on paired dusted and non-dusted plots (binary variable for DeltamethrinDust in the data file) in split colonies or separate adjacent colonies. Sampling of fleas occurred simultaneously on paired plots, thereby controlling for flea phenology when comparing flea parasitism on dusted and non-dusted plots. Each rodent was anesthetized with isoflurane and combed for 30 seconds (s) to remove fleas. During sampling of small rodents, less than 1 flea was found in only 5% of cases. No fleas were found in 88% of cases. Thus, we concentrated on indices of flea prevalence (FleaPrev in the data file) defined as detection or non-detection of at least 1 flea (binary 0/1).

2001—2004年，美国蒙大拿州与犹他州境内草原犬鼠（Prairie Dog, PD）群落中溴氰菊酯（deltamethrin）驱杀跳蚤的效果数据集。该数据采集自蒙大拿州与犹他州5个调查点位的12个草原犬鼠群落，涉及3种草原犬鼠：黑尾草原犬鼠（Cynomys ludovicianus，BTPDs）、犹他州草原犬鼠（C. parvidens，UPDs）以及白尾草原犬鼠（C. leucurus，WTPDs）。数据文件中共包含6种小型啮齿动物的样本，其样本量足以开展统计分析：鹿鼠、草蝗鼠、Ord袋鼠鼠、硬毛囊鼠、暗黑袋鼠鼠及灌丛田鼠。溴氰菊酯的驱蚤效果通过配对设计样地开展评估：在分割群落或相邻独立群落中设置喷施溴氰菊酯粉尘与未喷施的对照样地（数据文件中以二分类变量DeltamethrinDust标识处理组与对照组），对活体捕捉并麻醉的啮齿动物进行梳毛采样。配对样地同步开展跳蚤采样，以此在比较喷施与未喷施样地的跳蚤寄生水平时，控制跳蚤物候带来的混杂影响。每只啮齿动物均采用异氟烷（isoflurane）麻醉，以30秒的标准梳毛时长收集体表跳蚤。本次采样中，仅5%的个体仅检出不足1只跳蚤，88%的个体未检出跳蚤，因此研究聚焦于跳蚤感染率（数据文件中对应变量为FleaPrev）这一指标，其定义为是否检出至少1只跳蚤的二分类（0/1）变量。

背景概述

该数据集记录了2001年至2004年间，在美国蒙大拿州和犹他州的草原犬鼠群落中，使用溴氰菊酯控制小型啮齿动物身上跳蚤的效果研究。数据覆盖了三种草原犬鼠物种和六种小型啮齿动物物种，通过配对处理与未处理区域的对比，评估了跳蚤流行率的变化。数据集的关键特点包括对跳蚤控制效果的实证分析，以及基于现场实验的详细采样方法，旨在为野生动物疾病管理提供科学依据。
