Fire Ants Being Displaced By Venom-Neutralizing Crazy Ants
2014-02-14 07:08:22

[ Watch the Video: Crazy Ants Attack Fire Ants ] April Flowers for redOrbit.com - Your Universe Online In areas across the southeastern United States, invasive "crazy ants" are rapidly displacing fire ants by secreting a compound that neutralizes the fire ant's venom, according to a new study from The University of Texas at Austin. The crazy ant is the first known example of an insect with the ability to detoxify another insect's venom. The latest in a wave of ant invasions from the...

Crazy Ants Eating Electronics Across US Gulf States

Lawrence LeBlond for redOrbit.com - Your Universe Online A growing epidemic is eating its way across the Gulf Coast of the US and it seems there is little that can be done about it. The invasive ant species, Nylanderia fulva, commonly known as the tawny crazy ant, hairy crazy ant or Raspberry crazy ant, which was first discovered in Houston, Texas in 2002, is causing huge problems for people in at least four states around the Gulf of Mexico. The tawny crazy ant is an exotic species...

Ant Colony Evolution And Natural Selection

April Flowers for redOrbit.com - Your Universe Online City-states in ancient Greece that waited until their own harvest was in before attacking and destroying a rival community´s crops often experienced better long-term success. Ant colonies that show similar selectivity when gathering food have similar results, according to a new study from Stanford University. Deborah M. Gordon, Stanford biology professor, conducted a long-term study of harvester ants. Her findings, published in...

Ant Slave Rebellion
2012-09-26 19:13:14

Michael Harper for redOrbit.com — Your Universe Online There´s new evidence today ants that have been captured and made slaves by other ants aren´t simply taking their plights lying down. According to a new study, these slave ants are prone to try and take down their oppressors by sabotaging their families. The first signs of this kind of ant rebellion were noted by Johannes Gutenberg University Mainz (JGU) research professor Dr. Susanne Foitzik in 2009. However, in the...

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...

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...

A new study by biologists at Rice University and the University of Texas at Austin finds that the Texas leaf-cutter ant, Atta texana, adapted to the harsh Texas winters through their food. Although adapting to Texas winters may seem mild to those from northern climates, the ants' ancestors emigrated from the tropics. A texana, like all leaf-cutter ants, cuts leaves but does not eat them. "Leaf-cutters can't digest the nutrients of leaves directly, so they use a fungus called Attamyces as a...

Leafcutter ants, signature denizens of New World tropical forests, are unique in their ability to harvest fresh leaves to cultivate a nutrient-rich fungus as food. Now, this mutualism -- a complicated interplay of ants, fungi and a suite of bacteria -- is coming into sharper focus as a team of University of Wisconsin-Madison researchers has published the complete genome of the leafcutter ant, Atta cephalotes. The study, published today (Feb. 10, 2011) in the journal Public Library of Science...

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...
