啮齿动物对粮食安全和公共卫生构成严重威胁。啮齿动物控制可以减轻啮齿动物传播疾病风险的程度取决于控制在减少啮齿动物丰度方面的有效性以及对疾病流行病学的影响。针对马达加斯加的一个鼠疫流行区，这项研究比较了3种方法的有效性：活捕笼、捕捉器和灭鼠剂。2019年5月至10月期间，在房屋内实施了控制干预措施。跟踪瓦片监测啮齿动物的丰度。采集了鼠疫传播媒介啮齿类跳蚤。啮齿动物种群由Rattus rattus和Mus musculus组成。在陷阱成功方面，我们发现我们的活陷阱制度比快速陷阱更有效。虽然所有3种控制策略似乎都能在短期内减少室内啮齿动物活动，但我们没有发现长期效应的证据，到下个月，处理部位的室内啮齿动物丰度与非处理部位相当。地方性蚤，Synopsyllus fonquerniei，是一种主要的鼠疫媒介，通常发现于生活在户外的老鼠身上。虽然我们没有发现证据表明，它的丰度增加室内控制后，这可能是由于缺乏权力所造成的显着变化的S。fonquerniei丰度。S. fonquerniei在房屋中的可能性更大，当S。fonquerniei丰度在户外大鼠较高，这反过来又与高鼠丰度。我们的研究结果强调，控制策略需要考虑室内鼠蚤种群和室外种群之间的这种联系，以及鼠疫传播的任何潜在后果。针对马达加斯加的一个鼠疫流行区，本研究比较了3种方法的有效性：活捕集器，杀捕集器和含有抗凝血灭鼠剂的Kartman诱饵站。陷阱比陷阱更有效铁丝网BTS陷阱捕获了更多数量的鼠，这是马达加斯加鼠疫的主要宿主。控制策略需要考虑室内和室外鼠蚤种群之间的联系以及鼠疫传播的任何潜在后果。
Rodents represent a serious threat to food security and public health. The extent to which rodent control can mitigate the risk from rodent‐borne disease depends on both the effectiveness of control in reducing rodent abundance and the impact on disease epidemiology. Focusing on a plague‐endemic region of Madagascar, this study compared the effectiveness of 3 methods: live‐traps, snap‐traps, and rodenticides. Control interventions were implemented inside houses between May and October 2019. Tracking tiles monitored rodent abundance. Rodent fleas, the vector involved in plague transmission, were collected. Rodent populations consisted of Rattus rattus and Mus musculus. In terms of trap success, we found that our live‐trap regime was more effective than snap‐traps. While all 3 control strategies appeared to reduce in‐house rodent activity in the short term, we found no evidence of a longer‐term effect, with in‐house rodent abundance in treated sites comparable to non‐treatment sites by the following month. Endemic flea, Synopsyllus fonquerniei, is a key plague vector usually found on rats living outdoors. Although we found no evidence that its abundance inside houses increased following control, this may have been due to a lack of power caused by significant variation in S. fonquerniei abundance. The presence of S. fonquerniei in houses was more likely when S. fonquerniei abundance on outdoor rats was higher, which in turn correlated with high rat abundance. Our results emphasize that control strategies need to consider this connectivity between in‐house rat–flea populations and the outdoor populations, and any potential consequences for plague transmission. Focusing on a plague‐endemic region of Madagascar, this study compared the effectiveness of 3 methods: live‐traps, kill‐traps, and Kartman bait station containing anticoagulant rodenticide. Live‐trap regime was more effective than kill‐traps. Wire‐mesh BTS trap catch a higher number of Rattus rattus, the main reservoir of plague in Madagascar. Control strategies need to consider the connectivity between in‐house and outdoor rat–flea populations and any potential consequences for plague transmission.
