The USDA Forest Service funds hundreds of projects every year to protect our nation’s woodlands. Included in these research projects are several different types of pest management strategies spanning a wide range of pests, forest types, and ecosystems. A new article in the Journal of Integrated Pest Management reviews USFS pest-management research from 2011 to 2020, which helped manage over 2.2 million hectares of forest.
A new study on scale infestations in urban red maple trees adds evidence to the view that diversifying urban tree plantings is a sustainable and effective management strategy for otherwise difficult-to-manage pests.
Two decades after the arrival of the emerald ash borer in North America, plenty of misinformation remains about how best to manage its impact. A group of experts on this pest bust several myths about emerald ash borer in a new article in the Journal of Integrated Pest Management.
While their damage may be unsightly, many common caterpillar species that emerge in late summer to munch on tree leaves are generally not a significant threat to tree health. A new guide in the Journal of Integrated Pest Management takes a closer look at these late-season defoliators and offers tips for management.
The elm zigzag sawfly (Aproceros leucopoda) is now established in several places in North America.

Will it turn into a full-blown invasive species, or simply co-exist with native herbivores in natural and urban forests? At this point, we don't know. A new review highlights elm zigzag sawfly biology, ecology, and management strategies in the U.S.
