Asian Tiger Mosquito Found in Vermont (Oct 3, 2019)

Vermont Department of Health.

State Agriculture and Health officials announced that the Asian Tiger mosquito (Aedes albopictus) has been identified for the first time in Vermont. This normally tropical/subtropical species is a known disease vector for Zika, chikungunya and dengue viruses, infecting humans in countries where these diseases are present. The mosquitoes found in Vermont do not currently carry these viruses. Natalie Kwit, public health veterinarian with the Vermont Department of Health, said that while the discovery of Aedes albopictus in the state is notable, Vermont's climate is currently inhospitable for the mosquito species for most of the year, making it unlikely they will be spreading new diseases here any time soon. "The diseases they can carry are not endemic to our area, and in fact are rarely found anywhere in the United States," said Kwit. For more information, visit Vermont's Mosquito Surveillance Program.

Boxwood Blight
New Hampshire Department of Agriculture, Markets, and Food.
Boxwood blight is a disease affecting plants in the family Buxaceae including boxwoods (Buxus), Pachysandra, and Sarcococca plants. First detected in the U.S. in 2011, it has since been found in multiple states and provinces from the East Coast to the West Coast. Boxwood blight has now been confirmed on boxwood nursery stock in New Hampshire. New Hampshire nurseries, landscapers, town officials and residents responsible for boxwood plantings should learn the symptoms associated with boxwood blight. Watch for black lesions on stems, "zonate" brown spots on leaves leading to chlorosis, and leaf drop. If boxwood blight is suspected on recently purchased boxwoods, or plants in proximity to recently purchased boxwoods, please contact the Division and collect a sample for analysis by the UNH Plant Diagnostic Lab.
