Collective decision-making proves more efficient than individual selection Scientists at Arizona State University have discovered that ants utilize a strategy to handle "information overload." Temnothorax rugatulus ants, commonly found living in rock crevices in the Southwest, place the burden of making complicated decisions on the backs of the entire colony, rather than on an individual ant. In a study published in the early, online version of scientific journal Current Biology,...

April Flowers for redOrbit.com - Your Universe Online One thousand rare and protected ants have been fitted with tiny little backpacks to try and understand the social network of how a colony works. A research team from the University of York is fitting tiny radio receivers to a colony of hairy wood ants in the world's first experiment to find out how they communicate and travel between nests. The nests are located on the National Trust's Longshaw Estate in Derbyshire, UK, which is a...

Predatory beetles can detect the unique alarm signal released by ants that are under attack by parasitic flies, and the beetles use those overheard conversations to guide their search for safe egg-laying sites on coffee bushes. Azteca instabilis ants patrol coffee bushes and emit chemical alarm signals when they're under attack by phorid flies. In an article published online July 27 in the journal Ecology and Evolution, University of Michigan researchers and their colleagues show that...

World's Smallest Flies Decapitate Tiny Ants

The smallest fly ever discovered is just 0.40 millimeters in length, and is a member of a fly family that is known for 'decapitating' ants A new species of phorid fly from Thailand is the smallest fly ever discovered. At just 0.40 millimeters in length, it is 15 times smaller than a house fly and five times smaller than a fruit fly. The tiny fly, Euryplatea nanaknihali, is also the first of its genus to be discovered in Asia, and it belongs to a fly family (Phoridae) that is known for...

The Highly Diverse Ant Fauna Of The Philippines
2012-06-19 11:13:31

Intensive field work by researchers David General of the Palawan State University, The Philippines and Gary Alpert of the Museum of Comparative Zoology, Harvard University has led to the discovery of nine genera of ants that had never been recorded before in the Philippines. Another two new genera were discovered by other researchers in a remote mountain region. The study was published as the 200th jubilee issue of the open access journal Zookeys. About 30% of all currently known ant...

The Zombie-Ant Fungus Is Under Attack, Research Reveals
2012-05-03 06:23:50

A parasite that fights the zombie-ant fungus has yielded some of its secrets to an international research team led by David Hughes of Penn State University. The research reveals, for the first time, how an entire ant colony is able to survive infestations by the zombie-ant fungus, which invades an ant's brain and causes it to march to its death at a mass grave near the ant colony, where the fungus spores erupt out of the ant's head. "In a case where biology is stranger than fiction, the...

Campaign includes Homeowner Rebate, Parent Tool Kit, and Schools and Parks Savings Program Research Triangle Park, NC (PRWEB) May 01, 2012 Environmental Science, a division of Bayer CropScience LP, is helping maintain healthy homes and communities by educating homeowners, parents, and groundskeepers for schools and parks about the importance of fire ant prevention with the launch of the TopChoice® Fire Ant Prevention Campaign. As a part of the effort, a Homeowner Rebate, Parent Tool Kit...

Ants Remember Their Rivals' Scent

Researchers from the University of Melbourne report they have found that ant colonies share a collective memory for the odor of ants in rival nests. According to the new research, the ants use the information to identify the rival ants and compete, similar to how sports fans know each other by wearing their teams' colors. Study leader Professor Mark Elgar from the University's Department of Zoology said the ant colony's collective memory helps give an edge in a competitive world by...

The development of agriculture was a significant event in human cultural evolution, but we are not the only organisms to have adopted an agricultural way of life. In a study published online June 29 in Genome Research, researchers have sequenced the genome of a fungus farming leaf-cutting ant, revealing new insights into the genetics and molecular biology behind this unusual lifestyle. Found in Central and South America as well as the southern United States, leaf-cutting ants have evolved a...

Study increases understanding of 'coevolved mutualism' between ants and trees Survival in the depths of the tropical rainforest not only depends on a species' ability to defend itself, but can be reliant on the type of cooperation researchers discovered between ants and tropical trees. The research, published in Biotropica, reveals how the ants use chemical signals on their host tree to distinguish them from competing plant species. Once a competing plant is recognized the ants prune them to...

The ants, one of the most successful groups of insects, are of particular interest because they form advanced colonies, and can constitute up to 15 percent of the total animal biomass of a tropical rainforest. They belong to the order Hymenoptera and are close relatives of the vespoid wasps. Ants appear in amber, found in central New Jersey, believed to be from the Cretaceous period. It is thought that they evolved from the wasps that had appeared during the Jurassic period. They are...

Leafcutter ants are found in warmer regions of Central and South America. These remarkable social insects have evolved an advanced agricultural system. They feed on a specialized fungus that grows only in the underground chambers of the ants' nest. The ants actively cultivate their fungus, feeding it with freshly-cut vegetation and maintaining it free from pests and weeds. This is done by a symbiotic relationship with a colony of bacteria that grows on the ants that protect the fungus. The...

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...
