Detector dog trained to find Argentine Ants in New Zealand
Monday, October 05, 2015
A needy spaniel has proved a powerful weapon in the Hauraki Gulf fight against one of the world's 100 most invasive species.
Rhys Jones, a 4-year-old Welsh springer spaniel, has learned to sniff out Argentine ants, unwelcome invaders which can overwhelm native species by sheer weight of numbers.
The dog has been part of a breakthrough project which, in a New Zealand first, appears to have eradicated the unwelcome ants from part of Kawau Island.
Gulf biosecurity adviser Brian Shields, who looks after Rhys Jones, says the dog is the only one in the world trained to sniff out Argentine ants, or "argies" as he calls them.
The spaniel learned his skill by training on pieces of blotting paper containing ant pheromones.
Argentine ants produce a signature scent, and Rhys Jones is now attuned to it.

parasitic wasps to control Yellow Crazy Ants?
Monday, June 08, 2015
Australian scientists have been trying to control Yellow Crazy Ants on Christmas Island since the 1990's.  The ants, which form huge super-colonies prey on the unique red land crab that the island is famous for.  Baits work very well but are expensive and also kill coconut crabs (another land crab common throughout the Pacific.  Now scientists want to introduce a small wasp that preys on the scale insects that Yellow Crazy Ants ranch for the sugery secretions.  Stay tuned - this will be real interesting!

Interesting journal paper on ants as stow-aways
Wednesday, August 14, 2013
click on the blog heading to download the journal article.

The problem of invasive ants may be far worse than previously thought.

A Spanish team of scientists has found that larger than expected numbers of the insects are being unwittingly shipped around the world.

The researchers warn that many of these species are establishing colonies in their new habitats that could pose a threat to the environment, infrastructure and human health.

The research is published in the journal Royal Society Biology Letters. Lead author Veronica Miravete, from the University of Gerona in Spain, said: "Due to their small size, most ants are transported involuntarily in containers and other boxes, together with soil, wood, ornamental plants and fruits etc, on ships or airplanes."

Tiny globetrotters

The research team looked at the numbers of exotic ants in the Netherlands, the United States and New Zealand. They found far more of these accidental stowaways than had previously been reported.

Extrapolating from this data, they estimate that 768 exotic ant species could have been introduced around the world through trade routes. Of these, they believe that more than 600 species could have established new colonies.

Dr Miravete said: "The number of ants arriving is very large and 85% of the introduced species are able to establish successfully. This indicates that there are many introduced species that are living around us as of yet undetected. While not all animals that move to a new region pose a threat, some can wreak havoc - and invasive ants are some of the worst alien offenders.

In Europe, aggressive Argentine ants have been building mega-colonies, and they are out-competing local ant populations, which has sent ripples through the ecosystem....
