Invasive Disruptors
Invasive Insects
Asian Tiger Mosquitoes
The range of the Asian tiger mosquito is expanding in the United States, particularly into Connecticut and other northeastern states. Infection rates of West Nile Virus and other mosquito-borne diseases, such as Dengue and Zika, are likely to rise, over the long term, as a warming climate creates more favorable habitats for mosquitoes. Much of Connecticut is expected to get warmer and wetter over the coming century, enhancing mosquito populations by creating more suitable habitat.

Technical Note: The “Invasive Disruptors” described in this section are species that are not native to Connecticut that have the potential to upset the ecological balance or threaten public health. Invasive species have been identified as the cause in decline of at least 48 percent of species listed as threatened or endangered under the United States Endangered Species Act.
Emerald Ash Borer
The emerald ash borer is a significant threat to Connecticut’s forests.
The emerald ash borer attacks ash trees almost exclusively. In Connecticut, ash trees make up just slightly less than three percent of the trees in the forest, most of which are white ash. The loss of ash trees in a forest stand also reduces vital habitat and allows undesirable invasive plants to fill the gap created. Movement of ash, in particular as firewood, nursery stock, logs and wood packaging materials, has been cited as the most likely means by which emerald ash borer has spread so rapidly.
