A destructive, invasive beetle that kills ash trees, the emerald ash borer (EAB), has been confirmed in Delaware, making it the 28th state to have found the insect, the Delaware Department of Agriculture announced today. Delaware will be added to a federal quarantine already in 27 other states restricting the interstate shipment of all ash wood and wood products - ash nursery stock, green lumber, waste, compost and chips - as well as hardwood firewood of all species.

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.
