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]
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 [7] 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.
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]
Fire ants use track pheromones to mark the path from the colony to feeding sites. Trace pheromones are mainly known in insects living in colonies, which mark their paths with low-volatile substances such as higher molecular weight hydrocarbons. Ants in particular often mark the path from a food source to the nest in this way. [77]
