In their experiments, the researchers used sophisticated extraction techniques to obtain purified amounts of piperdeine and piperidine from the venom glands of both red and black imported fire ants.
In this case they are testing the venom, several ant species use different techniques to tend gardens of fungi so I wonder how this would work?
Most Poisonous Insect in the World
I was somewhat shocked by this information and didn’t realize that the Harvester Ant was even a contender in this category, but here is the information:
If you want to know the record holder for the most poisonous insect in the world, then you’re in the right place. The Maricopa harvester ant ranks on top. Also called Pogonomyrmex maricopa, it is one of the most common species of harvester ant species found in Arizona, and is considered the most venomous insect in the world. The Maricopa harvester ant is best known for the toxicity of its venom. Its LD50 value is 0.12 mg/kg (injected intravenously in mice), which means that 12 stings can kill a 2 kg rat. In comparison, the LD50 of the honey bee is 2.8 mg/kg — more than 20 times weaker. In humans, a Pogonomyrmex sting produces intense pain that can last up to 4 hours. These types of ants are far more venomous than fire ants.
Workman’s Comp and those bugs…
I would probably venture that most people wouldn’t consider that a bug bite might fall under a workman’s compensation claim. Read this article at http://www.ReduceYourWorkersComp.com by Rebecca Shafer, J.D. on Workers Comp Claims from Spiders, Bees, Fire Ants, Fleas, Mosquitoes, Bedbugs, Wasps, Hornets, Lice, Scorpions, Ticks, Mites, Bites, and Stings.
I think most of us don’t even think before we pick up something in the yard or garage, but maybe we should. That spider or scorpion is going to react and not in a good way. Put on gloves before you move anything that has been laying around.
A few tips:
Don’t stack things next to outside of your home.
Where gloves when moving items.
Garages and sheds are notorious for unwanted visitors, use caution.
Inspect your property monthly for signs of activity.
If you notice a hole, fill and patch it. If you notice bees call a Pest Management Professional.
If you’re allergic maybe you should consider having a key ring (picture from their site) or bracelet http://www.goodsforgiving.com

We do have a variety of Fire Ants here in Arizona and I have seen some research done in Florida and other states on this little wasp.
Here is a link to the Arizona Department of Agriculture on their work on the Red Imported Fire Ant. http://www.azda.gov/PSD/RedImportedFireAnt.htm and
The red imported fire ant, is a very invasive species from Brazil to Argentina and has now staked a claim in the Southwest US. Typically more aggressive than our native Arizona fire ants, having entered the United States through the port of Mobile, Alabama in the 1930s probably aboard a ship. In the 1990’s, they moved westward, traveling aboard trucks, trains and trailers with infested cargoes such as sod, plants, compost, possibly used farm equipment. This ant then made its way to far western Texas and Arizona.
