The winter of 2011-2012 was a mild one in the New York City area, and the following summer saw the lowest population density of nymphal blacklegged ticks (Ixodes scapularis) in the region since the Vector Ecology Laboratory at Fordham University had begun measuring it in 1987. And the ticks that were collected did not survive […]
