UMass Extension’s Landscape, Nursery, and Urban Forestry Program and the Extension Fruit Program will hold a series of free Tuesday webinars focusing on the impact, monitoring, and management of invasive insects in Massachusetts and elsewhere. Topics will include invasive forest pests, spotted lanternfly, the biological control of winter moth, Asian longhorned beetle updates, planned detection surveys in Massachusetts and New England, and more!
On Tuesday January 26th, UMass Entomologist Joseph Elkinton will present a webinar on Successful Biological Control of Winter Moth in Eastern New England from 11:10 to 12:10 am.
The winter moth, Operophtera brumata, an inchworm caterpillar that is native to Europe, became a devastating invasive defoliator of many species of forest and shade trees in eastern New England beginning in the late 1990’s.
Dr. Elkinton will discuss a biological control effort based on the introduction of the specialist fly parasitoid Cyzenis albicans. Each year for 14 years, the Elkinton lab collected and reared C. albicans from British Columbia and released them across sites in the northeastern United States. By 2016 they have documented a decrease in the winter moth population along with an increase in parasitism rates by C. albicans.
