In November of 2017, a tick species previously unknown to the US called Haemaphysalis longicornis, or the Asian longhorned tick, was discovered both on a sheep and in a pasture in New Jersey. Since then, this new tick species has been found in eight additional states, including 17 counties and one city in Virginia.

The Alabama Department of Agriculture and Industries (ADAI) has initiated a new social media campaign to raise awareness of the dangers cogongrass poses to the state. With agriculture and natural ecosystems at risk, ADAI is calling on Alabamians to recognize this threat and share the information.

Cogongrass has now infested more than 75 percent of Alabama's counties. This federally regulated noxious weed was introduced in the U.S. in 1911 as packing material in the port of Mobile. In the decades since, it has greatly expanded and become more dangerous. Visit www.alcogongrass.com to learn how to spot cogongrass and report it when it blooms again in the spring.

The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has developed a publicly available dashboard that displays the results from nation-wide avian influenza virus (AIV) monitoring in wild bird populations. Data presented in the dashboard can identify increased AIV risk and can provide information to poultry producers, wildlife managers, and members of the public on AIV activity in their area.

For the last seven decades, Cornell University’s College of Agriculture and Life Sciences (CALS) has been leading the fight against nematodes—invasive, microscopic worms that can destroy seasons' worth of crops. However, researchers had been working in a facility that lacked the infrastructure to keep pace with their innovative work. On August 1, 2019, thanks to a $1.2 million grant from New York State and another $400,000 in federal funding, CALS cut the ribbon on the new Golden Nematode Quarantine Facility, located on the Cornell campus in Ithaca, NY. The facility is the only research program in North America with expertise in biology, resistance breeding and management of potato-cyst nematodes. At the lab, Cornell scientists work in tandem with the U.S. Department of Agriculture (USDA) Agriculture Research Service (ARS).

Forest Service scientists have published a guide synthesizing best practices for controlling these tiny bugs. It promotes a strategy of combining insecticide use with adelgid-eating insects.

Invasive tegu lizards from South America are currently established in four locations in Florida and negatively impact native, ground-nesting animals in the Greater Everglades Ecosystem. Two newly published research studies from the U.S. Geological Survey show that, depending on their size and body condition, tegu lizards could survive in cooler, northern climates.

The Argentine black and white tegu is a large lizard from South America currently inhabiting the Florida counties of Charlotte, Hillsborough, Miami Dade and St. Lucie. Tegus are introduced to the U.S. through the pet trade and then likely released from captivity into the environment. "Several lines of evidence from recent USGS research studies published from 2018 to 2021 now provide clear indication for managers that the entire southeast portion of the United States is at risk of tegu establishment if lizard releases continue unabated," said Amy Yackel Adams, a USGS research ecologist.

Researchers from Dickinson College and the U.S. Geological Survey collaborated on field research to understand the ability of human searchers to detect the invasive brown treesnake (BTS) on the island of Guam. Due to their nocturnal and tree-dwelling habits, these snakes are extremely difficult to detect, especially when they are present at low densities in an area. A new study "Use of visual surveys and radiotelemetry reveals sources of detection bias for a cryptic snake at low densities" published in the journal Ecosphere, helps explain why and provides valuable information on optimizing search methods and search locations that could be valuable if the BTS was accidentally introduced to a snake-free island.

Agricultural Research Service (ARS) researchers in Florida have developed “attract-and-kill” traps to control Asian citrus psyllids in the suburbs where citrus trees are popular landscape plantings.

Emerald ash borer was first confirmed in New York in June 2009 near Randolph, in western Cattaraugus County. The rapid spread of the beetle through North America is most likely due to the transport of infested firewood, ash nursery stock, unprocessed ash logs, and other ash products. In an effort to slow the continued spread of EAB, both Federal and New York State agencies have instituted quarantines of infested areas to regulate the transport of ash products.
