The Connecticut Agricultural Experiment Station (CAES) in cooperation with USDA APHIS Plant Protection and Quarantine (PPQ) announce the detection of single live adult spotted lanternfly, Lycoma delicatula, in Southbury, CT. While no other spotted lanternflies were found upon surveying the immediate area, a live insect strongly suggests others may be present within easy transport from somewhere in the region. Additional surveys in the area are planned.

The spotted lanternfly is an invasive sap-feeding planthopper that was discovered in Berks County, Pennsylvania in 2014. It is native to China, India, and Vietnam. It attacks many hosts and has the potential to severely impact Connecticut’s farm crops, particularly apples, grapes, and hops, as well as a number of tree species like maple. Early detection is important for the protection of Connecticut businesses and agriculture. The public is urged to report potential sightings of this invasive pest to ReportSLF@ct.gov. For more information, see the CAES Pest Alert [PDF, 1.9 MB].

Integrated Pest Management (IPM) is a sustainable and scientific approach to managing pests. IPM practitioners base decisions on information that is collected systematically as they integrate economic, environmental and social goals. This approach applies to any situation, agricultural or urban, and is flexible enough to accommodate the changing demands of agriculture, commerce and society.

The University of Connecticut IPM Program staff members work directly with and provide educational outreach to commercial growers, natural area managers, groundskeepers, educators and the general public in Connecticut. In addition, they conduct research and offer extension programs in these areas: Fruit, Greenhouse, Invasive Species, IPM Curriculum, Nursery, Turf & Landscape and Vegetables.

Scientists from the Connecticut Agricultural Experiment Station (CAES) are reporting that Beech Leaf Disease (BLD) has increased dramatically in both severity and distribution in 2022 compared to 2021. First detected in lower Fairfield County in 2019, BLD is now widespread on American beech (Fagus grandifolia) throughout all eight Connecticut counties, with symptoms most severe in Fairfield, New Haven, Middlesex and New London Counties. Given that BLD is now widely established throughout Connecticut, reports of BLD to CAES and DEEP are no longer requested.

The Emerald ash borer was first found in Connecticut during the week of July 16, 2012. Since that first find in Prospect, EAB has been found in many other parts of the state, particularly in towns in central and western Connecticut. DEEP, the CT Agricultural Experiment Station, USDA APHIS PPQ and the U.S. Forest Service are working together with local partners to slow the spread of the insect and to take steps to minimize its impact. This will be a long-term effort on the part of all involved.

These plants are known to be invasive or potentially invasive in Connecticut and are on Connecticut's list of Invasive and Potentially Invasive Plants. They are known to be present only in relatively low numbers at limited locations in Connecticut. These species should be considered for control and eradication efforts in the state when resources are available. If you find these species: Report your findings immediately to the CT Invasive Plant Coordinator at reportinvasives@uconn.edu.

This guide is intended to assist with identification of invasive plants and provide information on controlling these problem plants. Included are both non-chemical means of control as well as information on proper use of herbicides where chemical controls are needed. The choice of control measure depends on the size and nature of the infestation. If dealt with early enough, invasive plant problems can often be eliminated by non-chemical methods. However, a herbicide-based approach may be required to control an infestation that has become well established or widespread.
