New research from the University of Florida has found that red fire ant invasions around the world in recent years can now be traced to the southern United States, where the insect gained a troublesome foothold in the 1930s. Native to South America, the ant has been believed to be contained there and in the southeastern US, before turning up in far off place over the past two decades. Genetic tests on ants in California, China, Taiwan, Australia and New Zealand has traced them back to...

Researchers from a pair of California universities have successfully sequenced the genome of the Argentine ant, shedding light on exactly why the species has thrived and leading to hopes that the knowledge might lead to the development of more effective pest control solutions. The draft genome of this specific creature, known scientifically as Linepithema humile, is one of three published by experts at University of California, Berkeley (UC Berkeley) and San Francisco State University in the...

Mate selection, foraging and defense mechanisms explored at ESA's Annual Meeting In this time of global change, understanding the basics of animal behavior and environmental interactions is just as important as predicting and planning for widespread impacts. Ecological scientists will assess the fundamentals of animal behavior"”such as plant toxin detection in bushbaby foraging"”and current adaptations to global change"”like defense mechanisms of native lizards to red...

Detecting exotic pests before forest and agricultural invasion In the 1930s, soil used as ballast to weigh down cargo ships from South America to Mobile, Alabama introduced the red imported fire ant to the southern United States. Since then, the ants have been found as far north as Maryland and as far west as California, shorting out streetlights and eating through crops and native plants in the process. Plant pests like the fire ant cost the U.S. an estimated $37.1 billion per year in...

British scientists fitted rock ants with tiny radio-frequency ID tags to determine the process by which ants select a new home. University of Bristol researcher Elva Robinson and colleagues gave the ants the choice of a nearby poor nest or a good nest located farther away. The researchers found the colonies selected the superior site although it was nine times farther away than the alternative. And, the scientists said, the best nest was chosen despite the fact that very few individual ants...

New study shows the age of victims determines how fire ants respond to aggressorsPretending to be dead is an effective self-defense strategy adopted by young fire ant workers under attack from neighboring colonies. This tactic makes them four times more likely to survive aggression than older workers who fight back. As a result, these young workers are able to contribute to brood care and colony growth to ensure the survival and fitness of their queen. These findings by Dr. Deby Cassill from...

LUBBOCK, Texas -- Imported red fire ants have plagued farmers, ranchers and others for decades. Now the reviled pests are facing a bug of their own. Researchers have pinpointed a naturally occurring virus that kills the ants, which arrived in the U.S. in the 1930s and now cause $6 billion in damage annually nationwide, including about $1.2 billion in Texas. The virus caught the attention of U.S. Department of Agriculture researchers in Florida in 2002. The agency is now seeking commercial...

TALLAHASSEE, Fla. -- The first sentence of the first chapter of Walter Tschinkel's new book says it all: "I love fire ants." The Florida State University myrmecologist - a biologist who specializes in ants - has spent 35 years studying red imported fire ants, aggressive stinging insects that most Southerners consider a pest of the first order if not an outright scourge. Tschinkel takes exception to that notion in "The Fire Ants." The 723-page epic, published by Harvard University Press,...

Fire ants are stinging ants of the genus Solenopsis, of which there are 266 species. They include Solenopsis invicta, commonly known as Red imported fire ant (RIFA). Each colony produces large mounds in open areas, and feeds on young plants and seeds. Solenopsis often attacks young animals and can kill them. For humans it has a painful sting - hence the name fire ant - and the aftereffects of the sting are deadly to some individuals. The worker ants are blackish to reddish and vary from...
