Desmodus rotundus is one of the wild animal species that has benefitted by habitat alteration and its population has increased due to livestock activities. Common vampire bat population management has been implemented across Mexico due to the economic losses to livestock production, inflicted by vampire bat attacks and rabies transmission. Yucatan is one of the seven most impacted states in Mexico by the number of cattle rabies cases per year. However, there is little research on D. rotundus populations such as the frequency and attack patterns to cattle. This study's objective was to analyze the relationship between D. rotundus abundance and number of bovines attacked in livestock landscapes in Yucatan. The study used data gathered by the State Committee for Protection and Promotion of Livestock in Yucatan through the National Campaign for Common Vampire Bat Population Control. Data collected from January 2014 to December 2017 was analyzed using Pearson correlation. Distribution maps on Desmodus rotundus abundance and number of bovines attacked were also created. Higher abundance of Desmodus rotundus and number of cattle attacks were observed in the central region of Yucatan, particularly in Izamal municipality. Positive correlations were found between (1) abundance of Desmodus rotundus and number of cattle in the region, (2) total number of cattle and number of cattle attacked, and (3) abundance of Desmodus rotundus and number of cattle attacked. We can conclude that there is a relationship between Desmodus rotundus abundance and frequency of cattle attacks in most municipalities across Yucatan. Some outstanding exceptions were observed, which require further detailed investigations.
吸血蝠是受益于栖息地改变的野生动物物种之一，其种群数量因畜牧活动而增加。由于吸血蝠攻击和狂犬病传播给畜牧生产造成经济损失，墨西哥各地已实施普通吸血蝠种群管理。尤卡坦是墨西哥每年牛狂犬病病例受影响最严重的七个州之一。然而，关于吸血蝠种群的研究很少，比如对牛的攻击频率和模式。本研究的目的是分析尤卡坦畜牧景观中吸血蝠数量与被攻击牛数量之间的关系。该研究使用了尤卡坦州畜牧保护与促进委员会通过全国普通吸血蝠种群控制运动收集的数据。对2014年1月至2017年12月收集的数据进行了皮尔逊相关性分析。还绘制了吸血蝠数量和被攻击牛数量的分布图。在尤卡坦中部地区，特别是在伊萨马尔市，观察到吸血蝠数量较多且牛被攻击的情况较多。发现（1）该地区吸血蝠数量与牛的数量之间、（2）牛的总数与被攻击牛的数量之间以及（3）吸血蝠数量与被攻击牛的数量之间存在正相关。我们可以得出结论，在尤卡坦的大多数市镇，吸血蝠数量与牛被攻击的频率之间存在关联。观察到一些显著的例外情况，需要进一步详细调查。
