Ants Remember Their Rivals' Scent
2012-02-22 05:49:02

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...

Smelly Ants Invade Hawaii

A common pest in the mainland United States known for its tropical smell now has a tropical habitat to go along with it. Odorous house ants - so called because they tend to invade houses and smell like coconut when smashed - have found their way to Hawaii. And, according to Purdue University entomologist Grzegorz Buczkowski, it doesn't seem as though they have plans to end their vacations. "Odorous house ants in Hawaii are not like they are here in natural areas where they live in small...

Ant colonies with more behavioral variety are more successful / New findings in ant behavioral research They attack other colonies, plunder and rob, kill other colonies' inhabitants or keep them as slaves: Ants are usually regarded as prototypes of social beings that are prepared to sacrifice their lives for their community, but they can also display extremely aggressive behavior towards other nests. The evolution and behavior of ants, in particular the relationship between socially...

By Louis Bergeron, Stanford University Stanford sophomores studying ants in a summer course discovered that the local ants were using poison to kill invading Argentine ants. The discovery provides new insight into the war between the local "winter ants" and the South American invaders who have shown up everywhere from California to South Africa. Argentine ants are taking over the world "“ or at least the nice temperate parts. They've spread into Mediterranean and subtropical climates...

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...

A group of 'friend or foe' scent molecules have been isolated from colonies of Argentine ants. Researchers writing in the open access journal BMC Biology identified and synthesized the scents, describing how applying them to worker ants resulted in attacks from their former colony-mates. Neil Tsutsui and colleagues, from the University of California, Berkeley, USA, worked with a team of researchers from the University of California, Irvine to carry out the ant experiments. He said, "Chemical...

Researchers have discovered a massive invasion of Argentine ants that have spread across continents with the help of human influence. What's more, the billions of ants that originated in South America appear to belong to the same colony, according to a team of researchers in Japan and Spain led by Eiriki Sunamura of the University of Tokyo. Researchers noted that the ants roaming across Europe, Japan and California appear to have similar chemical profiles of hydrocarbons on their cuticles,...

The prestigious Smithsonian Museum has been overrun with insects. A brand new exhibit, "Farmers, Warriors, Builders: The Hidden Life of Ants," debuts Saturday at the National Museum of Natural History and is open through Oct. 10. The display will include a living leaf-cutter ant colony from Ted Schultz, the museum's curator of ants. Also on display is a 6-foot-tall cast of an ant colony collected by Walter Tschinkel, a student of ant-nest architecture at Florida State University. There will...

U.S. entomologists say they have discovered how ants know when a nestmate has died and its time to remove the body from the colony. University of California-Riverside scientists say when an ant dies its body is quickly picked up by living ants and removed, thus limiting the risk of colony infection by pathogens from the corpse. Up to now most entomologists theorized dead ants release chemicals created by decomposition, thereby signaling their death. But in the new study, scientists working on...
