A Lesson From “Ant-stronauts” On The International Space Station
2014-06-24 03:24:15

Jessica Nimon, NASA A recent study on the International Space Station brings to mind Aesop’s fable of the Ant and the Grasshopper, and it is pretty amazing what we can learn from these industrious insects. The activities of a crew of ants that lived aboard the orbiting laboratory as part of the Ants in Space CSI-06 investigation are inspiring students and scientists alike. But the investigation has the potential to do far more than motivate; the data collected can teach us about...

Novel Attract-and-kill Approach Developed To Target Argentine Ants
2014-01-06 13:15:08

University of California - Riverside UC Riverside entomologists devise a technique that involves mixing a synthetic pheromone in insecticide sprays After being inadvertently introduced in the United States from South America, Argentine ants have successfully invaded urban, agricultural, and natural settings nationwide. In urban California, the Argentine ant is among the primary pest ants. For example, this particular species of ants makes up 85 percent of ants sampled by commercial pest...

Hardworking Sisters Allow Insect Colonies To Thrive

University of Edinburgh They are among the animal kingdom's most industrious workers … now a study reveals why colonies of ants and bees depend on females for their success. Altruistic workers in social insect colonies – such as ants, bees and wasps – are more likely to be female, because their maternal instincts make them better at caring for the queen's offspring. The findings come from a study of who does what in these highly organized insect societies. In these species, it...

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
2013-05-16 08:44:57

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...

Robot Ants Learn To Navigate A Maze
2013-03-29 10:50:18

Michael Harper for redOrbit.com — Your Universe Online It´s commonly known that ants navigate by scent. As each ant randomly wanders in search for food or shelter, it leaves behind a trail of pheromones which other ants will then follow. The result is that famous line of ants leading to a family picnic or a particularly sticky spill. Though this behavior has been observed for centuries, it´s something which Simon Garnier from the New Jersey Institute of Technology and...

Reproductive Workings Of A Harvester Ant Dynasty Uncovered By Stanford Scientist
2013-02-12 21:08:18

Stanford University For the first time, scientists have measured how successfully a queen ant establishes new colonies. The work by Stanford researchers revealed that the queen was still reproducing several decades after mating. Ants are just about everywhere you look, and yet it's largely unknown how they manage to be so ubiquitous. Scientists have understood the carnal mechanism of ant reproduction, but until now have known little of how successful the daughters of a colony are when...

Asian Needle Ants Displacing Other Aggressive Invaders
2013-02-11 10:07:43

North Carolina State University Researchers from North Carolina State University have found that one of the most aggressive invasive ant species in the United States — the Argentine ant — appears to have met its match in the Asian needle ant. Specifically, the researchers have found that the Asian needle ant is successfully displacing Argentine ants in an urban environment, indicating that the Asian needle ant — with its venomous sting — may be the next invasive...

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...
