Reflections on the Ecology and Epidemiology of Eastern Equine Encephalitis in the Northeastern United States: A Historical Perspective. In 2019, the northeastern eastern U.S. experienced the largest and most widespread outbreak of eastern equine encephalitis (EEE) in more than 50 years with 23 human cases including 8 fatalities and 42 equine cases across 7 states.  Although the scope of the outbreak was unprecedented for the region, it represented a recent trend of sustained resurgence and northward expansion of EEE activity in the northeast that began in 2003.  Factors contributing to this resurgence and expansion are complex but likely include (1) reforestation and wetland conservation, (2) suburban development adjacent to mosquito habitats and, (3) changes in average temperature and precipitation events related to climate change. In this presentation Dr. Andreadis will review the environmental, ecological and biological risk factors associated with EEE activity in the northeast and provide up-to-date information on the ecology, epidemiology, and management of EEE in the region including: the role of Culiseta melanura and other vector competent species in enzootic and/or epidemic transmission based on regional host feeding studies and virus isolation data, annual virus introduction via migrating birds and local overwintering based on phylogenetic studies of the virus, and challenges and issues concerning surveillance, human risk assessment, prevention, and both larval and adult control strategies. Theodore G.

Japanese Barberry and Blacklegged Ticks: A Surprising Connection. Invasive Japanese barberry tends to grow in abandoned agricultural lands and can grow in very dense infestations. These infestations retain daily relative humidity which makes for ideal tick habitat. This talk highlights 10 years of research in which we document this relationship and can show that Japanese barberry management results in fewer ticks and tick-borne pathogen, thus lessening risk to public health. Scott C. Williams, (203) 974-8609, Scott.Williams@ct.gov

Integrated Tick Management in Residential Connecticut. Nobody likes ticks, I mean nobody. You are most likely to pick up a tick (and potentially a pathogen they are carrying) on your own property, because that is where you likely spend the majority of your time. We have done research using different methods of tick control in differing combinations in residential areas throughout Connecticut that include targeting the ticks themselves, mice, and deer. This talk will discuss Lyme disease and tick ecology, will highlight the different products and strategies available, and reveal which combination with the least amount of toxicity was most effective. Scott C. Williams, (203) 974-8609, Scott.Williams@ct.gov

Tree Diseases New to New England (and worth knowing about). This presentation will discuss tree diseases that have the potential to threaten New England forests, both urban and natural. These include Phytophthora ramorum, the fungus-like “Sudden Oak Death” pathogen that has been ravaging forests of the western United States for over 20 years; Bretziella (formerly Ceratocystis) fagacearum, the oak-wilt fungus that has caused widespread loss of oaks in Texas, the Midwest, and southeast, and which has recently turned up in New York state; and Xylella fastidiosa, the xylem-limited bacterium responsible for bacterial leaf scorch on a variety of deciduous hosts, particularly oaks, from Texas to New Jersey. In each case, we will discuss the symptoms, the means of dispersal and spread, and, if applicable, the prognosis for treatment. If time permits, I will also touch on diseases that may not be new to New England, but which are increasing in severity, such as Caliciopsis canker, and “white pine needle disease complex.” Robert Marra, (203) 974-8508, Robert.Marra@ct.gov

Climate Change and Forest Health. The impact of climate change on forest health has two principle components. First, changes in weather patterns, which include longer periods of drought punctuated by heavier rain events, put trees under greater stress, leaving them more susceptible to pests and disease. Second, warmer average temperatures will increase the likelihood of the establishment of new pests and pathogens to which our native flora are currently naïve.  The synergistic effects of these two factors poses a critical threat to our forests and landscapes. Robert Marra, (203) 974-8508, Robert.Marra@ct.gov

 

Drought: Impact on Trees and Implications for Management. This presentation will begin with a discussion of changes in our regional weather patterns that have increased the intensity and duration of periods of drought. We will then discuss how drought impacts trees in both the short-term and long-term, focusing on how a tree’s physiology responds to drought, and how drought can increase the likelihood and severity of disease. We’ll conclude with a discussion about how best management practices can mitigate the effects of drought. Robert Marra, (203) 974-8508, Robert.Marra@ct.gov

CAES and the FDA Food Emergency Response Network (FERN). Post-September 2001, the federal government recognized that the US food supply was vulnerable to attack.  The response was to establish a network of laboratories around the country that would have similar equipment, methods, and expertise to respond to issues of national concern with the food supply. This network was established by the US Food and Drug Administration (FDA) and the US Department of Agriculture Food Safety and Inspection Service (FSIS) and is called the Food Emergency Response Network or FERN. The CAES Department of Analytical Chemistry has been a funded member of the FDA FERN since 2005; this presentation will cover our contributions to national food safety, including work on melamine, the response to the Deepwater Horizon Oil spill, the evaluation of food for toxic heavy metals such as inorganic arsenic, and active surveillance for organic contaminants of concern. Jason C.
