Application of the 4X bait was designed to give a coverage of 4.2 g mirex/ha and was delivered by aircraft, helicopter or tractor. 1x and 2x bait were also used. Use of mirex as a pesticide was banned in 1978. The Stockholm Convention banned production and use of several persistent organic pollutants, and mirex is one of the "dirty dozen". [3]
This makes many experts put some children on fire ant venom immunotherapy, while others do not. [54] [65] The recommended maintenance dose is between 0.5 mL of a 1:100 w/v 1:10 w/v WBE. [66] For fire ant venom immunotherapy, the most common maintenance dose is 0.5 mL of a 1:200 (wt/vol) dilution. [67]
Solenopsin is a lipophilic alkaloid with the molecular formula C 17 H 35 N found in the venom of fire ants (Solenopsis). It is considered the primary toxin in the venom [2] and may be the component responsible for the cardiorespiratory failure in people who experience excessive fire ant stings. [3]
These insect alkaloids can be efficiently extracted by solvent immersion of live fire ants [4] or by centrifugation of live ants [185] followed by silica-gel chromatography purification. [186] Tracking and dosing the extracted solenopsin ant alkaloids has been described as possible based on their absorbance peak around 232 nanometers.
Abamectin, is a member of the avermectin family and is a natural fermentation product of soil dwelling [1] actinomycete Streptomyces avermitilis. [2] Abamectin differs from ivermectin , the popular member of the avermectin family, by a double bond between carbons 22 and 25. [ 2 ]
In the 1930s, colonies were accidentally introduced into the United States through the seaport of Mobile, Alabama.Despite earlier views that cargo ships from Brazil docking at Mobile unloaded goods infested with the ants, [1] recent DNA research confirmed that the likely source population for all invasive S. invicta in the United States occurred at or near Formosa, Argentina, and virtually ...

[2] Imported red fire ant Solenopsis invicta was accidentally introduced into the United States in Alabama in the 1930s. Since then, its populated area has expanded across the country, including ...
