Agricultural Research Service (ARS) scientists in Kerrville, Texas, are developing and testing new interventions to eliminate cattle fever ticks within U.S. borders and mitigate the impact on the livestock industry. ARS is USDA's principal intramural scientific research agency, and this research promotes the USDA priority of promoting international food security.
The increased spread of infestation is likely due, at least in part, to the increasing populations of white-tailed deer and other wild hoofed animals along the Texas-Mexico border. To control disease-carrying ticks on deer, ARS entomologist J. Mathews Pound and his colleagues at the agency's Knipling-Bushland U.S. Livestock Insects Research Laboratory developed a device called the 4-Poster Deer Treatment Bait Station.
The bait station lures deer into a feeding apparatus that uses rollers to apply insecticide to the animal's head, ears and neck. As the deer grooms itself, it transfers the insecticide to other parts of its body, killing most of the ticks on the animal.
Pound and colleagues also have reformulated a broad-spectrum antiparasitic medication called doramectin into an injectable, time-release treatment. According to Pound, a single injection of the microspheres greatly reduces the number of treatments needed and protects cattle for up to four months, killing parasites and saving cattle ranchers considerable expense.
The treatment has been tested with excellent results on the island of St. Croix against the tropical bont tick, which transmits a disease called heartwater to cattle. Pound and his colleagues are working to extend the effective period to six months, which would be most useful in treating U.S. cattle for ticks.

The Fraunhofer FEP has been involved in developing processes and equipment for cleaning, sterilization, and surface modification for decades. The CleanHand Network for development of systems and technologies to clean surfaces, materials, and objects was established in May 2018 to bundle the expertise of many partnering organizations. As a partner in the CleanHand Network, Fraunhofer FEP will present the Network and current research topics of the Institute in the field of hygiene and cleaning at the parts2clean trade fair, October 23-25, 2018 in Stuttgart, at the booth of the Fraunhofer Cleaning Technology Alliance (Hall 5, Booth C31).
Test reports and studies on the cleanliness of European motorway rest areas, hotel beds, and outdoor pools increasingly appear in the press, especially during...
The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.
This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.
Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...
Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
