How Forest Service Research Protects U.S. Woodlands From Insect Pests
By David Coyle, Ph.D. Folks outside the forest entomology realm have likely heard of the USDA Forest Service but may have little knowledge of what this group actually does. Truth be told, they do a lot—from trail and road maintenance to fire suppression and prevention to management, this group is responsible for managing millions of acres of our nation’s forestland. But, in addition to the management aspect, the Forest Service (USFS) also conducts and funds research—lots of research.
What's Eating Your Pine Needles? Sawflies, Probably
Skip to content Brought to you by the Entomological Society of America Trending Topics: Research News•The Entomology Profession•Amazing Insects•Science Policy and Outreach By David Coyle, Ph.D. Conifer trees are incredibly common across the U.S. landscape and can be found nearly anywhere, including in yards, recreation areas, roadsides, and natural and managed forests.
Here We Go Again: Meet the Elm Zigzag Sawfly, Another Non-Native Forest Pest
By David Coyle, Ph.D. Sometimes I feel like a broken record writing (and reading) articles for Entomology Today about invasive forest pests. This time, it’s the elm zigzag sawfly (Aproceros leucopoda), which was first detected in Quebec, Canada, in summer 2020. Of note, this detection was made from an observation on the public crowdsourced citizen science website iNaturalist further supporting the usefulness of such online platforms.
Climate, host and geography shape insect and fungal communities of trees - Scientific Reports
|
Abstract Non-native pests, climate change, and their interactions are likely to alter relationships between trees and tree-associated organisms with consequences for forest health. To understand and predict such changes, factors structuring tree-associated communities need to be determined. Here, we analysed the data consisting of records of insects and fungi collected from dormant twigs from 155 tree species at 51 botanical gardens or arboreta in 32 countries.

Beware, Boxwoods: Another Pest is On the Horizon
By David Coyle, Ph.D. Shaped into hedges, balls, cylinders, and any other shape imaginable, boxwoods (species in the genus Buxus) are some of the most ubiquitous and hearty landscape shrubs around. So many boxwood bushes are planted in landscapes that you might not even notice them—until those dark green, compact plants are gone, of course. Then people notice. One of the biggest threats to boxwoods is Cydalima perspectalis, colloquially called the box tree moth.
The Ambrosia Beetle Megaplatypus mutatus: Tiny but Destructive
By David Coyle, Ph.D. Although ambrosia beetles are a crucial part of natural systems around the world, helping to break down woody material and recycle nutrients, these tiny insects are rarely noticed except by those actively working with (or looking for) them. They spend most of their lives inside woody things, like a tree stem or branch, making them difficult to just casually bump into.
New Guide Highlights IPM for Boxwood Pests
By David Coyle, Ph.D. Boxwood, while not native to North America, is a common evergreen landscape plant on this continent. It has shown no signs of becoming invasive despite being planted in landscapes as early as 1653! This plant is extremely common throughout the U.S. and many boxwood (Buxus) species and cultivars are used to provide a touch of green in urban, suburban, and rural managed landscapes.
Another Pest of Pollinators: Small Hive Beetle Management in Honey Bee Colonies
By David Coyle, Ph.D. There’s been a lot of attention given to pollinators recently, especially native pollinators—which include bees, wasps, flies, beetles, and several other organisms—but also those species used commercially. Yes, I’m talking about European honey bees, (Apis mellifera). Their colonies are often moved great distances and are essential to produce many food crops. Like ’em or not, European honeybees are a critical spoke in the agricultural wheel.
New Guide Details IPM for Thousand Cankers Disease in Black Walnut
Thousand cankers disease is a fungal disease primarily affecting walnut trees, spread by the walnut twig beetle (Pityophthorus juglandis). While impacts vary greatly, diagnostic tools and an updated integrated pest management program are urgently needed. A new paper in the Journal of Integrated Pest Management highlights strategies that can be effective in managing TCD in commercial walnut plantations.
Effective Management Remains Elusive for Beetle That Eats Almost Anything
The Japanese beetle (Popillia japonica) is a widely known invasive species in North America. Adults feed on more than 300 plant species and can be downright difficult to manage. A new guide in the open-access Journal of Integrated Pest Management reviews their invasion history, ecology, and management.
A Budding Problem: Managing Corn Earworm in Commercial Hemp
The corn earworm (Helicoverpa zea) is an emerging pest of commercial hemp production throughout the U.S. Boring through stalks and feeding on reproductive structures, this pest presents several management challenges for hemp producers. While integrated pest management strategies for more traditional agricultural crops are established, much work is still needed to develop effective IPM for the corn earworm in hemp. Shown here is a corn earworm larva feeding on a hemp plant flower bud.
It Takes a Village: Our Continued Efforts to Manage Invasive Species in the U.S.
From sea to shining sea: Invasive insect species pose threats U.S. agriculture, natural resources, and public health. Just three examples include the spotted lanternfly (Lycorma delicatula) (left) on the East Coast and spreading to the Midwest, the giant hornet Vespa mandarinia (middle) in the Pacific Northwest, and the little fire ant (Wasmannia auropunctata) (right) in both Florida and Hawaii.
Managing Southern Pine Beetle Infestations in a Changing Forest Environment
The southern pine beetle (Dendroctonus frontalis) is the most impactful pest of southern pines in the eastern U.S. A new article in the Journal of Integrated Pest Management reviews SPB suppression methods, which generally involve removing the infested (and some uninfested) trees to halt the spread of the outbreak. (Photo by Matt Bertone, Ph.D.) By David Coyle, Ph.D. If you’ve ever driven through the southeastern U.S., you’ve probably seen miles and miles of roads lined with pine trees.
International Biosecurity Program Prevents Spread of Invasive Moth
The moth Lymantria dispar asiatica (adult female shown here) has been unintentionally introduced to North America several times in the last few decades. Through a complex monitoring and management program, officials have been able to prevent this pest from establishing in North American forests. A new report in the open-access Journal of Integrated Pest Management gives an inside look at this success.
Inch by Inch, Fall Cankerworms Will Eat Your Trees
The fall cankerworm (Alsophila pometaria) is a common, native defoliator of hardwood trees throughout North America. Prone to outbreaks, this insect can cause severe damage on trees and be a public nuisance. Landscape-level management is rarely necessary, but control measures may be worthwhile on individual trees. (Photo by William M. Ciesla, Forest Health Management International, Bugwood.org) By David Coyle, Ph.D. When I was a kid, I spent a lot of time outdoors.
Exciting But Dreadful: New Invasive Forest Pest Arrives in South Carolina
The Asian longhorned beetle (Anoplophora glabripennis), a federally regulated invasive woodboring pest, was recently discovered in South Carolina—hundreds of miles from the nearest known infestation. Federal and state officials are working hard to try to eradicate this pest, and there are many research questions and opportunities associated with this infestation.
Hitchin' a Ride: A Review of Firewood as Vector of Forest Pests in North America
Many pests can survive in firewood, some for more than three years. Shown here is a longhorned beetle larva (family Cerambycidae) emerging from split firewood. A new review in the Journal of Economic Entomology looks at what we know about forest pest movement in firewood and what we can do about it.
The Warmer the Better: Gloomy Scale Can Be a Big Problem on Urban Landscape Trees
Gloomy scale (Melanaspis tenebricosa) is a problematic pest on urban landscape trees because the insect reaches extremely high densities in response to conditions common to urban landscapes, like drought and high temperatures. Shown here is an adult female (pink) with its dorsal armored covering, knonw as a “test,” removed. The ventral test is flat, white in the center and black around the edge, and attaches to the bark of the host tree.
There's a New Tick in Town
The Asian longhorned tick (Haemaphysalis longicornis) was discovered in the U.S. in 2017, and it poses health threats to both animals and humans. A new guide in the Journal of Integrated Pest Management outlines the different management strategies that are being developed, and surveillance and prevention are key to reducing this non-native arthropod’s impact. Shown here are a nymph (left) and adult female.
Residential Pest Management: What Do Homeowners Know, and What Do They Do?
Homeowners can face a wide variety of pest management challenges in caring for their lawns and gardens, such as damage caused by a hairy chinch bug (Blissus leucopterus hirtus) infestation, shown here. How much do homeowners know about pesticide use, and about integrated pest management in general? Are people just using the “spray and pray” tactic, or are they using multiple forms of pest management together as part of an integrated plan?
Client Alert: The CDC Eviction Order: What Does it Mean for Landlords? | JD Supra
Under a broad claim of authority, on September 4, 2020, the Centers for Disease Control and Prevention (“CDC”) issued an Order (85 FR 55292) to temporarily halt certain residential evictions effective immediately until December 31, 2020.
Collaboration Leads to Documentation: Tracking the Spread of Tar Spot on Corn in the U.S.
A new paper published in July in the Journal of Integrated Pest Management highlights tar spot on corn. First discovered in the U.S. in 2015, tar spot can cause substantial reductions in corn productivity through reduced ear weight, poor kernel development, and vivipary (the premature germination of corn kernels while they’re still on the cob).
Stop, Collaborate, and Listen: Interdisciplinary Project Engages Design Students in Promoting IPM
A new paper in the Journal of Integrated Pest Management reports on an interdisciplinary collaboration between one university’s IPM and design programs to develop new ideas for promoting and educating stakeholders on the value of integrated pest management.
Here We Go Again: Another Invasive Pest in Florida Citrus
Nipaecoccus viridis, known as the hibiscus mealybug or lebbeck mealybug, is native to Asia but was first spotted in Florida in 2009. Since then it has been found on various host plants, but in late 2018 it was first identified infesting citrus groves. The mealybugs’ cryptic feeding behavior, including under the sepals on citrus fruits make them easy to miss. Shown here, a portion of the sepal is cut away to reveal the mealybugs beneath.
The Path
Lou sat in the dark, drinking wine straight from the bottle. Dirty plates were everywhere: coffee table, kitchen bench, floor. He hadn’t shaved in months. The curtains were pulled. The air was stale. Proof civilisation was ending played on the television, filling the room with a dismal, bluish light; every channel was awful, everywhere proof mankind had made itself redundant. Nothing meant anything anymore. It’s all just a matter of time. Lou stared vacantly into space as he sipped his cheap pinot noir.
A People Problem and Plant Disease: The Economics of Pest Management in Citrus Greening
Trees infected with citrus greening disease first exhibit leaf discoloration, then defoliation and twig dieback, followed by root loss and eventually death. (Photo by H.D. Catling, Bugwood.org) By David Coyle, Ph.D. Citrus greening, also known as Huanglongbing or HLB, is one of the worst citrus diseases in the world.

People Matter: Why the Human Factor Is Essential for Successful Integrated Pest Management Programs
An activity during an IPM training program. Photo credit: Ryan Gott, Ph.D., Phipps Conservatory. By David Coyle, Ph.D., and Ryan Gott, Ph.D. Integrated pest management (IPM), used for decades worldwide, is critical to the control of pests in myriad systems, including traditional crops, natural resources, horticulture, and urban systems (e.g., schools). IPM traditionally consists of iterations of scouting for pests, managing them, and recording and evaluating the results.
Commentary: We can battle climate change and invasive species in our own backyards
White-flowered Bradford pear trees line many streets in the Eastern United States. Some think this tree is pretty, and I won’t argue that point. But have you ever smelled the flowers? They have a pungent scent, to say the least. And as the Bradford pear is a nonnative tree, it has the capacity to “go rogue” (where it’s called the callery pear), and now many roadsides and old fields are covered in white flowers every spring.
Biological Control for Hemlock Woolly Adelgid: Where Do We Stand?
Hemlock woolly adelgid (Adelges tsugae) is a highly destructive invasive insect pest of hemlock trees in both urban and forested environments in eastern North America. Since its introduction more than 50 years ago, this aphid-like pest has caused significant mortality in eastern hemlock (Tsuga canadensis) and Carolina hemlock (T. caroliniana) in North America.
Bark Beetles, Drought, and Prescribed Fire
Bugwood.org Southern Regional Extension Forestry, 2018 Leslie Boby, David Coyle, Joseph O'Brien, and Benjamin Hornsby Can presecribed fires contribute to the risks of bark beetle infestations and widespread tree mortality? Fire is an integral component of many ecosystems in the southern U.S., especially shortleaf and longleaf pine systems. The use of prescribed fires not only serves an ecological purpose, but can be a very useful forest management tool.
5 More Things I've Learned About a Career in Extension
When I last wrote about switching from research to extension, I lamented a little about the difficulties in obtaining a tenure-track job. (This is a well-documented and often-covered issue in academia; see essays by Dr. Jeremy Yoder and by fellow Entomological Society of America member Dr. Christie Bahlai). I talked about eschewing the traditional tenure-track job hunt to focus on an extension program I created. Well, fast-forward a year, and here I am in a tenure-track job.
