This collection of publications in NAL's Digital Repository provides access to and addresses a number of topics concerning the gypsy and the related brown-tail moths, from biological control methods to tree banding to quarantine practices. The bulk of the documents were published from 1891 to 1923 by various agencies in the area of the initial infestation, including the State Board of Agriculture for Massachusetts, New York, and Rhode Island, but also include some more modern USDA publications.

Seeds that float in the air can hitchhike in unusual places – like the air-intake grille of a refrigerated shipping container. A team of researchers from the USDA Forest Service, Arkansas State University, and other organizations recently conducted a study that involved vacuuming seeds from air-intake grilles over two seasons at the Port of Savannah, Georgia. The viability of such seeds is of significant interest to federal regulatory and enforcement agencies, and the project required a shared stewardship approach. Their findings were recently published in the journal Scientific Reports.

Seeds from 30 plant taxa were collected from the air-intake grilles, including seeds of wild sugarcane (Saccharum spontaneum), a grass on the USDA's Federal Noxious Weed List. (scroll to view list on Federal Noxious Weeds Program). Federal noxious weeds pose immediate, significant threats to agriculture, nursery, and forestry industries. Although a lovely grass and useful in its native range, wild sugarcane has the potential to join cogongrass, stiltgrass, and other nonnative species that have become extremely widespread in the U.S.

In 2016 NASS began to collect data on honey bee health and pollination costs. Provides reliable, up-to-date statistics help track honey bee mortality.

Rodrigo Krugner, an entomologist with the Agricultural Research Service (ARS) in Parlier, California, has found an innovative way to control insect pests in California vineyards: tapping into the vibrational signals they use as mating calls.

Krugner’s efforts have mainly focused on glassy-winged sharpshooters, which spread a bacterium that causes Pierce’s disease in vineyards and costs the California grape industry an estimated $104 million a year. Growers use chemical sprays to control the pests, but insecticides also kill beneficial insects, leave residues, and become less effective as the insects develop resistance.

Changing climate conditions have bearing on every aspect of biological invasions, in some cases worsening existing problems. Climate change is creating new pathways for invasive species to be introduced, such as shipping routes that open up as sea ice retreats. Warmer temperatures can allow existing invasive species to expand their range into habitat that is currently too cool. Similarly, impacts to native species and people may change if new conditions affect invasive species abundance. Climate change may make existing invasive species control tools less effective, such as aquatic barriers that require minimum water flows.

Imagine a devastating plant disease that sweeps the land, decimating crops. For Florida’s citrus growers, that apocalyptic vision is not a horror movie, but a reality: since it was first identified in the Sunshine State in 2005, citrus greening disease has reduced Florida’s citrus production by a whopping 70%. Without any treatment or cure available, desperate growers have cut down infected trees or abandoned their groves entirely. Scientists have been racing to come up with a solution. Now, an ARS research team believes it may have one, in the form of: stingrays.

Invasive fruit flies, such as the Oriental, Mexican, Mediterranean, and European cherry fruit fly, pose threats to many U.S. commercial and homegrown crops. If established, these flies could cause significant economic losses, requiring costly treatments to protect fruits and vegetables and reducing the marketability of infested fruit both locally and abroad. What’s at stake? The market value of invasive fruit fly-host commodities totaled approximately $11.7 billion in the United States in 2022. Approximately $8.3 billion of that was from California and $2.9 billion from Florida.
