Sheep and cattle-killing disease carriers never take a break

New research reveals surprising behavior of bluetongue virus-carrying midges during winter. Previously believed to disappear in colder months, these tiny flies remain active and pose a continued threat to cattle and sheep. Bluetongue virus is prevalent in cattle across the United States, with implications for international trade. Although not all infected animals die, the symptoms can be severe. The study sheds light on the persistence of the virus during winter and challenges previous assumptions about midge activity. By trapping midges on warm days, researchers demonstrated their ongoing presence and development throughout the winter season. The findings emphasize the need for improved management strategies, such as using insect repellants, to minimize virus transmission. Understanding the behavior of these insects is crucial to mitigate the economic and health impacts of bluetongue outbreaks.
