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.

DEC and DAM Announce Confirmed Finding of Spotted Lanternfly in Albany and Yates Counties: State Agencies Encourage Public to Report Findings of Invasive Pest (Sep 11, 2018)

New York State Department of Environmental Conservation.

The New York State Departments of Environmental Conservation (DEC) and Agriculture and Markets (DAM) today confirmed that spotted lanternfly (SLF), an invasive pest from Asia, has been found in Albany and Yates counties. A single adult insect was discovered in a vehicle in the Capital District. In addition, a single adult insect was reported on a private Keuka Lake property in Penn Yan, Yates County. Anyone that suspects they have found SLF is encouraged to send a photo to spottedlanternfly@dec.ny.gov. Please note the location of where the insect was found, egg masses, and/or infestation signs. DEC and DAM also encourage the public to inspect outdoor items such as vehicles, furniture, and firewood for egg masses. Anyone that visits the Pennsylvania or New Jersey Quarantine Areas should thoroughly inspect their vehicle, luggage and gear for SLF and egg masses before leaving and scrape off all egg masses.

DEC and DAM Release Fall 2019 Update on Spotted Lanternfly in New York State (Nov 6, 2019)

New York State Department of Environmental Conservation.

The New York State Departments of Environmental Conservation (DEC) and Agriculture and Markets (DAM) today announced that although freezing temperatures will kill off adult spotted lanternflies (SLF), the public is urged to stay vigilant and report overwintering egg masses. In the fall, SLF will lay their eggs on any flat surface such as vehicles, firewood, outdoor furniture, stone or other items which can be inadvertently transported to new areas. If this insect becomes established in New York, it could impact New York's forests, agricultural and tourism industries. "To date, there has not been a documented spotted lanternfly infestation in New York, but I encourage the public to stay aware and be ready to report egg masses or other signs of this insect to help prevent infestations," said DEC Commissioner Basil Seggos.

Assistance from the public is crucial in limiting the movement of SLF and protecting New York's natural resources. DEC and DAM are urging the public to inspect outdoor items such as vehicles, outdoor furniture and camping equipment for egg masses or insects, and report any sightings by sending photos and location information to spottedlanternfly@dec.ny.gov. Anyone that visits locations of SLF quarantines in other states should look for and remove insects and egg masses on items before leaving those areas. For more information, please visit DEC's spotted lanternfly webpage.

Emerald Ash Borer Confirmed in South Dakota (May 9, 2018)

South Dakota Department of Agriculture.

The South Dakota Department of Agriculture (SDDA) has confirmed that an infestation of emerald ash borer (EAB) has been discovered in northern Sioux Falls. This is the first confirmed infestation in South Dakota. Emerald ash borer is an invasive insect that has killed tens of millions of ash trees in at least 32 states. On May 9, 2018, Secretary Mike Jaspers implemented an Emergency Plant Pest Quarantine in order to prevent or reduce the spread of the EAB. This emergency quarantine is effective immediately.
