The woolly adelgid, an invasive insect that kills native hemlock trees, has been plaguing the area around Cayuga Lake for years. In an effort to stop the woolly adelgid, the beetle Laricobius nigrinus is being used as a biocontrol method. Recently, Mark Whitmore, a member of the Cornell Department of Natural Resources and entomologist, released 800 of these beetles into the VanRiper Conservation Area in the hopes of reducing the woolly adelgid population there. Along with this biocontrol method, the Cornell Plantations are working with the Finger Lakes Land Trust to apply insecticides to the hemlocks until the introduced beetle population develops fully.
