In the case of fire ants, the venom consists mainly of alkaloid (>95%) and protein (<1%) components. [2] Stinging ants cause a cutaneous condition that is different from that caused by biting venomous ants. Particularly painful are stings from fire ants, although the bullet ant's sting is considered by some to be the most painful insect sting.
The venom plays a central role in the biology of Red imported fire ants, such as in capturing prey, [1] and in defending itself from competitors, [2] assailants, [3] and diseases. [4] Some 14 million people are stung annually in the United States, [ 5 ] suffering reactions that vary from mild discomfort, to pustule formation, swelling, [ 6 ...

“Ants have palates, and if they don’t take the bait immediately, you’ll need to try a different formula,” says Suiter. “It’s not like they’re going to change their minds.”
Poison oak is a leafy shrub that grows in shady areas of your yard where it can reach six feet in height. The leaves and stems of the western poison oak plant ( Toxicodendron ) can release an oil ...
Rather, when wandering ants cause electrical shorts, they attempt to sting the wire and produce powerful semiochemicals, including defensive and recruitment pheromones. [13] The chemical signals draw additional ants to the short. The only effective protection is to bar ants from the equipment physically or with insecticides.
A dose of 10 5 pfu of poneratoxin was sufficient to kill the S. frugiperda larvae, and a dose of 10 ng could paralyze them. [1] Based on these experiments, scientists believe poneratoxin can make a good candidate as a bio-insecticide because of its neurotoxicity to other insects, making it capable of immobilizing or even killing insects ...
This is an example of chemical signaling, which explains why ants all appear to sting at once. Similar to the two-part process of the fire ant bite and sting, the harvester ant will attach to the victim with its mandibles , and so proceed by pivoting around the site, allowing the ant to repeatedly sting and inject venom into the region.
