Marketing strategies and suggestions for contacts with other growers are also given.
Chestnut Blight Disease in our Forests. The chestnut blight fungus came into this country in the late 1800's on Japanese chestnuts and reduced our native chestnuts to understory shrubs that sprout, become infected, die, and sprout again. I am working on a biological control for this disease, and breeding chestnuts for resistance.
Chestnuts in the 21st Century. Chestnut breeding has been done at The Experiment Station since the 1930's, and the program is now focusing on producing timber and orchard trees with resistance to chestnut blight disease and chestnut gall wasp.
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.
West Nile Virus: A Retrospective Look at an Emerging Mosquito-Borne Disease in the Western Hemisphere. In the summer of 1999, West Nile virus, a mosquito-borne flavivirus native to Africa, Asia and Europe, was discovered in the western hemisphere for the first time when it caused an epidemic of human disease in New York City. Over the course of four years this exotic virus, which likely originated from Israel, spread at an unprecedented rate across the United States and southern Canada, and has emerged as a major seasonal public health concern. More than 50,000 human cases and 2,400 fatalities have been reported thus far and the virus has become a permanent part of the landscape. In this lecture, Dr. Andreadis will review the emergence and spread of West Nile virus in North America, examine the ecology and epidemiology of the virus in the state, and describe Connecticut’s annual program to monitor and combat this mosquito-borne disease.
Ecology and Epidemiology of Mosquito-Borne Viruses in Connecticut: An Analysis from Twenty Years of Research and Surveillance. The ecology and epidemiology of a cadre of mosquito-borne viruses that cause human disease and currently circulate in Connecticut and the northeast, including Cache Valley, eastern equine encephalitis, Jamestown Canyon, LaCrosse and West Nile, will be presented based on over twenty years of arbovirus research and surveillance in the state.
Global Climate Change and Mosquito Borne Diseases. The potential impact of global climate change on the emergence and spread of exotic mosquitoes and both native and exotic mosquito borne diseases in the United States and elsewhere will be discussed.

Nine Important Plant Diseases of Eastern North America. A 1-½ hour discussion of the history, diagnostics, and biology of each of the nine diseases that have been, continue to be, or may be of significance in our region: Beech Bark Disease, Ramorum Blight, Oak Wilt, Bacterial Leaf Scorch, Thousand Canker Disease, Chrysanthemum White Rust, Boxwood Plight, Plum Pox Virus, and Ash/Elm Yellows. This lecture should be suitable for First Detector Training programs. Note: This presentation can be scaled down to fit within a smaller time frame by discussing a subset of these diseases.
Tree Diseases You Should Know About. This presentation will introduce the study and principles of plant pathology in the context of three historically important tree diseases: chestnut blight, beech bark disease, and Dutch elm disease.
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.”
Climate Change and Forest Health. The impact of climate change on forest health has two principal 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.
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.
Tropical Storms, Hurricanes, and SuperStorms: Impacts and Influences on Tree Diseases. Using lessons learned from distant (1938) and more recent (Tropical Storm Irene and Hurricane Sandy) weather events, this presentation will introduce tropical storms and how we define them, as well as the proximal and distal effects of storms that pose the greatest risks to trees, and how these effects can facilitate and exacerbate tree diseases.
Fungi in Forests and Landscapes: Friends or Foes? Most people can recognize a mushroom when they see one, but have you ever wondered how that mushroom got there? And what it’s doing there, anyway? Ever wondered about that yellow blob that seems to appear spontaneously in your mulch or on your lawn? Did you know that many plants, including the trees in our forests, could not survive without the important associations their roots establish with fungi? This talk will introduce the audience to the fascinating world of that poorly understood Kingdom Fungi.
Introduction to Mycology: The Study of Fungi. This presentation introduces the Kingdom Fungi, through an introduction to what defines a fungus, and an overview of the breadth and diversity of this fascinating and important group of organisms, taking you well beyond the realm of visible mushrooms and into the less easily viewed world of fungi that live underground, and those that cause plant and animal diseases.
Ramorum Blight: Is Phytophthora ramorum a Threat to Connecticut’s Forests and Landscapes? P. ramorum has been devastating the coastal oak forests of California and Oregon for at least ten years. The pathogen has a wide host range that includes species native to the Northeast (for example, oak, rhododendron, and mountain laurel), as well as numerous species important to the nursery industries of both the West Coast and Connecticut. Because of the high volume of plant material shipped from the West Coast to Connecticut, surveys of Connecticut nurseries are conducted annually to monitor for presence of the pathogen. This talk will include an overview of the biology and history of this important disease, a discussion of the threat the pathogen could pose to our forests and landscapes, and the diagnostic strategies used in monitoring and detection.
Natural History of Target Canker of Birch. Neonectria ditissima, the causal agent of Target Canker (also known as Neonectria Canker), is an ascomycete fungus that has been described as “the most widespread and damaging species” of northeastern forests. While the fungus produces perennial cankers on a wide range of broad-leaved trees in temperate eastern forests, it is notably associated with beech bark disease, and causes particularly disfiguring cankers on black birch (Betula lenta), a native of northeastern forests. Neonectria Canker is also an important disease of fruit trees, particularly apple and pear. This talk will cover the biology and natural history of the disease, and discuss methods being used to study how changes in forest composition over the past 100 years have altered the dynamics of this disease.

Development of Hydrogen Peroxide-based Techniques for Destruction of Chemical Pollutants in Water and Soil. I will discuss our methods for purifying soil and water using a safe and inexpensive oxidizing agent and environmentally friendly catalysts (iron salts and solar light).
Bed Bugs. Bed bugs were reintroduced to the United States starting in the late 1990’s through international trade and shipping. They quickly became ubiquitous and are now well established. These insects have had a close association with humans for well over 223,000 years and tracing their history and our efforts at ridding ourselves of them is a fascinating story. Additionally, their numerous survival behaviors have enabled this ever-present parasite to survive with ease and not “go away.”
Delusions of Infestations (DI). Delusional Infestation is a psychiatric illness characterized by patients holding a monothematic, tenacious and often fixed belief of an infestation of their skin, body, or immediate environment, which is not supported by objective medical evidence. This is a story of hardship and suffering and the Entomologist is often the expert patients seek out for help since many believe they are infested by insects and/or mites. Understanding the condition, its causes and how it develops over time in a supportive collaboration with physicians, pest management professionals, psychiatrists, and other medical professionals, patients can be helped. This allows them to return to a quality of life they once enjoyed.

Planting for the Bees’ Needs. Bees are critically important for pollination of our crops and our native plants. We get many of our ideas about bees from what we know of honey bees, but honey bees are only one of the 349 species we have in Connecticut. In this talk, Dr. Kimberly Stoner describes the diversity of bees and their life cycles, and how we can create habitat for them to survive and thrive. She also discusses the routes by which bees are exposed to pesticides and the controversies over restricting or banning certain pesticides because of their effects on bees.
The Rice That Helped America Grow. A variety of rice named Carolina Gold was the first food product that America exported to Europe, and helped the coastal colonies achieve economic independence. Learn the legend of how this rice came to America, how West African ingenuity helped it thrive and become a local and international delicacy, and how it was almost lost forever before being revived by backyard enthusiasts in the past few years.
Plant Genetic Resistance- An Important Piece of Integrated Pest Management. Plant genetic resistance is one of the most important tools we have in fighting disease and insects. What does it really mean for a plant variety to be “resistant” to a disease or insect? How are new resistant plants bred (or engineered) and brought to the field? Why do some types of resistance fail after a few years, and others last a long time? Finally, what management strategies could be employed to make resistance genes more durable and effective?

Learn how proper species selection can maximize the benefits and minimize the problems of street trees in our town forests and homes. The talk includes tips for planting new trees and shrubs, general tree care, and how to spot potential problems on your property.
Deer and Rabbit Repellent Effectiveness in Connecticut. Deer and rabbits can cause increased damage to vegetable gardens and flower beds, frustrating residential gardeners. Where deer/rabbit removal or fencing is not feasible, repellents can be used successfully. This talk reports repellent effectiveness results from various trials we have conducted over the years using different commercially available products.
Deer Management Strategies. Overabundant deer can be a direct threat to public safety in terms of vehicle collisions and increased tick abundances and can threaten native and residential landscapes. Deer management can be a very emotional topic, on both sides of the issue. This talk focuses on alternatives to lethal management and frankly discusses the effectiveness of the various traditional and nontraditional techniques.
Deer as Transporters of Exotic Plant Seeds. Deer consume many pounds of vegetation daily and retain it for 24 hours before depositing its remnants elsewhere. When thinking of animals dispersing seeds, most people think birds as being the main player. While this may be true, our research has shown that deer are surprisingly large contributors to seed dispersal, of primarily the seeds of exotic plants.
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.
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.
Healthy Forests, Healthy People. After decades of research involving ticks and different forested habitats, we have concluded that forests in poor health, in general, have the highest tick abundances and largest risk to the public. This talk will discuss what makes a forest unhealthy, will show tick abundances in different forested settings, and will provide a justification for proper forest management to benefit wildlife and the public alike.
