白鼻症是一種侵襲性真菌疾病，2006 年開始在美國蔓延，導致北美的蝙蝠數量下降。由於失去這些蝙蝠捕食農業害蟲，殺蟲劑的使用量增加了 31%，這導緻美國受影響縣的嬰兒死亡率上升。多項研究層顯示在母體血清、胎盤和臍帶中發現農藥。預計未來15年北美 52% 的蝙蝠物種面臨滅絕的危險。

the white-nose syndrome, an invasive fungus disease, began spreading in the US in 2006 and caused declines in bat population in North America. Without these bats to prey on agricultural insect pests, the used of insecticide has increased 31%, and this led to the rise of infant mortality rates in affected US counties. Several studies have found pesticides in maternal serum, placenta and umbilical. 52% of bat species in North America are at risk of extinction.
