Lately, when we hear about bats in the news it's often in the context of emerging infectious diseases. Yet, despite potential public health threats, bats are extremely important to the health of our natural ecosystems.

As silvery moonlight washed across the Montana meadow, it sent long shadows over the grass. Tonight, I didn’t need the gentle clang of the grazing bell to tell me where the horses were feeding. My leggy quarter horse was as brightly silver-white as the full moon. The distant lowing of cows across the meadow confirmed that all was well. Somewhere in the distance, a wolf pack was probably making evening rounds, but tonight they likely wouldn’t visit this meadow. I swung up into my horse trailer’s tack room and wriggled into my sleeping bag as my dogs made way for my arrival. The next morning I’d rise at daybreak and head toward the sound of the cattle.

After weeks of searching, Washington State Department of Agriculture (WSDA) entomologists–—using a radio tag provided by USDA’s Animal and Plant Health Inspection Service and a trap developed by the USDA’s Agricultural Research Service–— have located and eradicated the first Asian giant hornet (AGH) nest ever found in the United States. For months, WSDA had been trying to find the nest they knew must exist near Blaine, WA, because of AGH detections in the area. But finding the nest proved extremely challenging since the hornets build nests in forested areas, typically in an underground cavity.

Many claim that 2020 has been a year of chaos and calamity, but for one rare squirrel, it might be a year of hope and new beginnings. The Delmarva Fox Squirrel (DFS) is a subspecies of fox squirrel found on the eastern shore of Maryland, Southern Delaware and Virginia. This pudgy, slow squirrel with its signature size and silvery-white coat has become a conservation success story in Maryland. Habitat loss along with other additive factors landed them on the Federal endangered species list in 1967. Protection and management efforts benefited DFS and in 2015, populations reached stable limits and they were officially delisted in Maryland. In parts of Delaware, DFS populations were not as prolific and numbers began to dwindle over time leaving only a few small populations.

Did you first learn about rabies through the children’s book or movie “Old Yeller”? Rabies has changed drastically over the last century in the United States, moving from a majority of cases occurring in domestic animals like the literary canine hero, to a disease occurring predominantly in wildlife. That makes rabies a significant wildlife management challenge in the U.S. today, and a reason the United States Department of Agriculture and our partners in rabies prevention and elimination recognize World Rabies Day on September 28, 2020. This is a day of global action that started in 2007 to raise awareness for rabies prevention and to enhance control efforts worldwide.

Did you know that USDA has declared August as Tree Check Month? That’s because August is the peak time of year to spot the Asian longhorned beetle (ALB)—an invasive wood-boring beetle that attacks 12 types of hardwood trees in North America, such as maples, elms, horse chestnuts, birches and willows. Checking trees for the beetle and the damage it causes is one way residents can protect their own trees and help USDA’s efforts to eliminate this pest from the United States.

The United States Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS), the agency I work with, will host virtual hiring events focused on military veterans this Summer and Fall as the agency looks to fill positions to help carry out our Agency mission to safeguard American agriculture. The first veterans virtual hiring event (PDF, 2.6 MB) APHIS will offer is on August 11, 2020 in partnership with the Department of Veteran Affairs Veterans Readiness and Employment Program (VR&E), with another to follow in the Fall. Veterans, transitioning from military life, make excellent recruits for the APHIS team—as a veteran, I know.

A few of the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) affiliated canines are showing off their “sniffs” and talents to the world in the Disney+ weekly series, “It’s a Dog’s Life with Bill Farmer”. The 10-episode series that began airing on Friday, May 15 will feature APHIS operated Hawaiian Geese canine teams, APHIS trained brown tree snake canine teams and APHIS trained Beagle Brigade teams. The canine teams will be featured in the season’s final two episodes.

It’s not the first time that European honey bees and other pollinators in the United States have encountered invasive pests, with the parasitic Varroa mite being the most noteworthy. For years, researchers and beekeepers have wondered what the next invasive pest of concern would be. Perhaps Tropilaelaps mites, a parasitic mite that feeds on bee brood? Or an Asian honey bee, which is known to outcompete our European honey bees? Ultimately, it was the Asian giant hornet, making a confirmed appearance in Washington state during winter of 2019.

As cases of chronic wasting disease (CWD) continue to rise, USDA’s Animal and Plant Health Inspection Service (APHIS) is looking to genetics for new and innovative ways to reduce the prevalence of this brain-wasting disease in farmed and wild deer and elk populations. Working in collaboration with Texas A&M University and Texas Parks and Wildlife, APHIS has identified a handful of promising regions in the white-tailed deer genome allowing the researchers to distinguish animals highly susceptible to CWD with greater than 80 percent accuracy.
