Bio-control in the Garden: New Research and Techniques for Invasives HOR 402

Lisa Tewksbury, Manager, Biological Control Laboratories, University of Rhode Island and Bruce Wenning, Land Stewardship Manager for Land's Sake, Inc.
1 Session
Sat Dec 1 9:00am-noon [HB]

Invasive species are here to stay, and their numbers will only rise with increasing globalization. But this doesn't mean defeat for landscapers and gardeners. What it does require is considering the dynamics of ecosystems and developing methods for keeping aliens in check.

In this program on problem insects and weeds of New England, Lisa Tewksbury, an entomologist and manager of the University of Rhode Island's Biological Control Laboratories, will present a variety of bio-control techniques, including her lab's current work on lily leaf beetle, birch leaf miner, Cyprus spurge, purple loosestrife, common reed, swallow-wort, as well as on hemlock woolly adelgid. She'll update us on success stories and challenges, and when we can expect to see the results of some of the newly introduced "fighters."

Bruce Wenning will present various methods used and the successes and failures he experienced in removing invasive plants at Habitat, an urban wildlife sanctuary.

Entomologist Lisa Tewksbury has worked as a research associate at University of Rhode Island in the plant sciences department for the past 20 years and as manager of the URI biological control lab for the past ten years. The lab conducts research on insect natural enemies of invasive insect and weed species.

Bruce Wenning is land stewardship manager for Land's Sake, Inc. in Weston, Massachusetts. Formerly the grounds manager of Habitat, a Massachusetts Audubon Society sanctuary, he was in charge of the formal gardens and invasive plant management projects. His specialty is the biology and ecology of soil arthropods.
