Balsam Woolly Adelgid: A Foe to Firs

December 23, 2022 by Guest Contributor Leave a Comment

balsam fir courtesy Wikimedia user Abies balsamea 2 ’Tis the season for balsam fir, the fragrant evergreen that adorns our homes through the winter holidays. Its scent and long lasting needle retention make this the most popular Christmas tree and wreath species. Balsam fir is also an important timber species used for lumber. Native to North America, balsam fir (Abies balsamea) grows throughout the more northern latitudes and highest elevations of the country, including in the Northeast.

However, researchers predict a northward shift of balsam fir in an increasingly warming climate. Warmer temperatures are also contributing to a rise in populations of an exotic invasive pest – balsam woolly adelgid (Adelges piceae) – which feeds on fir trees, affecting their health and viability as lumber and Christmas trees.

Beetles, Silver Flies Being Used Against Hemlock Woolly Adelgid Infestations

October 8, 2022 by Editorial Staff Leave a Comment

Hemlock Woolly Adelgid provided by DECHemlock trees are being threatened by an invasive insect called the hemlock woolly adelgid (HWA). Only the size of a sesame seed, this tiny aphid-like insect has the ability to take down an entire forest by feeding on and weakening hemlock trees – causing mortality within 5-7 years if left untreated.

As a foundation species, hemlocks are an important component of forests and provide many beneficial ecological services, like filtering water, shading streams, and providing food and habitat for wildlife.

Winter Chores: Check for Hemlock Woolly Adelgid

January 23, 2022 by Editorial Staff Leave a Comment

HWA submitted to iMapInvasives by observer 21340Winter is the best time to survey for invasive hemlock woolly adelgid (HWA), a tiny insect that is a big problem for forests and water resources in the Northeast.

HWA threatens the native conifer, the eastern hemlock, which makes up large portions of the canopy in many New York forests and maintains water quality in streams by providing shade. HWA lives, reproduces, and feeds on hemlock trees, killing trees within four to 10 years. [Read more…] about Winter Chores: Check for Hemlock Woolly Adelgid
