昆虫病原真菌，特别是绿僵菌属和白僵菌属的真菌，已显示出作为节肢动物媒介控制工具的巨大前景。然而，这些药物尚未针对鼠疫跳蚤媒介进行评估。接触浓度为 2 × 108 分生孢子 m-2 的真菌涂层纸 3 小时，感染处理组中 > 90% 的跳蚤幼虫尸体。与对照相比，感染降低了暴露于真菌的幼虫的存活率。接触 M. anisopliae (HR = 4, p<0.001) 和 B. bassiana (HR = 3.5, p<0.001) 的幼虫每日死亡风险分别高出四倍或三倍以上。两种真菌都能成功感染并杀死巴西 X. brasiliensis 幼虫，暴露后的中位存活时间 (MST±SE) 为 2±0.31 天。这些发现证明需要进一步研究昆虫病原真菌对跳蚤的生物防治潜力。
Entomopathogenic fungi, particularly those belonging to the genera Metarhizium and Beauveria have shown great promise as arthropod vector control tools. These agents, however, have not been evaluated against flea vectors of plague. A 3-h exposure to the fungi coated paper at a concentration of 2 × 108 conidia m-2 infected >90% of flea larvae cadavers in the treatment groups. The infection reduced the survival of larvae that had been exposed to fungus relative to controls. The daily risk of dying was four- and over three-fold greater in larvae exposed to M. anisopliae (HR = 4, p<0.001) and B. bassiana (HR = 3.5, p<0.001) respectively. Both fungi can successfully infect and kill larvae of X. brasiliensis with a pooled median survival time (MST±SE) of 2±0.31 days post-exposure. These findings justify further research to investigate the bio-control potential of entomopathogenic fungi against fleas.
