We investigated the effectiveness of integrated tick management (ITM) approaches in reducing the burden of infection with Borrelia burgdorferi, Babesia microti, and Anaplasma phagocytophilum in Ixodes scapularis. We found a 52% reduction in encountering a questing nymph in the Metarhizium anisopliae (Met52) and fipronil rodent bait box treatment combination as well as a 51% reduction in the combined white-tailed deer (Odocoileus virginianus) removal, Met52, and fipronil rodent bait box treatment compared to the control treatment. The Met52 and fipronil rodent bait box treatment combination reduced the encounter potential with a questing nymph infected with any pathogen by 53%. Compared to the control treatment, the odds of collecting a parasitizing I. scapularis infected with any pathogen from a white-footed mouse (Peromyscus leucopus) was reduced by 90% in the combined deer removal, Met52, and fipronil rodent bait box treatment and by 93% in the Met52 and fipronil rodent bait box treatment combination. Our study highlights the utility of these ITM measures in reducing both the abundance of juvenile I. scapularis and infection with the aforementioned pathogens.
我们研究了综合蜱虫管理（ITM）方法在减少伯氏疏螺旋体、微小巴贝斯虫和嗜吞噬细胞无形体感染的负担方面的效果，在 Ixodes scapularis 中。我们发现，在粘虫金龟子（Met52）和氟虫腈鼠饵盒处理组合以及白尾鹿（Odocoileus virginianus）联合清除、Met52 和氟虫腈鼠饵盒处理中，遇到觅食若虫的几率降低了 52%，而与对照组相比。Met52 和氟虫腈鼠饵盒处理组合降低了遇到任何病原体感染的觅食若虫的接触潜力 53%。与对照组相比，在联合鹿清除、Met52 和氟虫腈鼠饵盒处理中，从白足鼠（Peromyscus leucopus）中收集感染任何病原体的寄生性 I. scapularis 的几率降低了 90%，在 Met52 和氟虫腈鼠饵盒处理组合中降低了 93%。我们的研究强调了这些 ITM 措施在减少幼年 I. scapularis 的数量和上述病原体感染方面的效用。
