Our forests, landscapes, and gardens seem to be constantly assaulted by new invasive weed and insect pests. Lily leaf beetle, winter moth, Japanese knotweed, hemlock woolly adelgid, garlic mustard, mile-a-minute vine, and even kudzu are already well-established in southern New England and the emerald ash borer has its sights on us. Ironically, in many cases, the best opportunity to manage these pests involves introducing additional non-native species – generally insects – that regulated them in their native homeland. Dick Casagrande of the University of Rhode Island will speak at Elm Bank on Thursday, August 2, beginning at 7 pm, on the Biological Control of these invasive pests.
Dr. Casagrande will discuss current programs, opportunities and limitations for biological control of landscape pests of particular importance in our region. He will also answer questions and offer practical advice to homeowners interested in controlling (or enhancing) insects in their homes and yards.Â The lecture fee is $12 for Mass Hort members, $15 for non members, and pre-registration is not required.Â For more information, visit www.masshort.org.
