Teasing apart ant venom

Science, 2018
Organismal Biology![Figure][1] The giant red bull ant has complex multifunctional venom. PHOTO: KAAREL OLESK/GETTY IMAGES Ant venoms are primarily made up of poorly characterized polypeptides. Robinson et al. combined transcriptomics and mass spectrometry–based proteomics to determine the mechanism of action of giant red bull ant venoms.

Novel Dialkylpiperidines in the Venom of the Ant Monomorium delagoense

Journal of Natural Products, 1990
New 2,6-dialkylpiperidines found in the venom of the ant Monomorium delagoense include cis- and trans-2,6-di(4-pentenyl)-piperidine [2], cis- and trans-2-(4-pentenyl)-6-pentylpiperidine [4], and cis- and trans-2-(6-heptenyl)-6-(4-pentenyl)-piperidine [7], whose structures were confirmed by synthesis.

Pyridine Alkaloids in the Venom of Imported Fire Ants

Journal of Agricultural and Food Chemistry, 2019
Venomous imported fire ants cause significant medical problems. Alkaloids are an important component of imported fire ant venom. Piperidine and piperideine alkaloids have been identified in fire ant venom. In this study, we studied the venom alkaloids of the red imported fire ant, Solenopsis invicta Buren, the black imported fire ant, Solenopsis ...

Isolation of a Hemolytic Component of Fire Ant Venom

Science, 1959
A crystalline hemolytic principle, shown to be a constituent of fire ant venom and having the properties of an amine, was isolated from crude extracts of whole ants. The chromatographic procedure of isolation is described, and a preliminary report is given about some properties of the substance.

Histamine release by fire ant (Solenopsis) venom

Toxicon, 1978
Abstract Venoms from the fire ants Solenopsis invicta and S. geminata were free of detectable histamine but caused histamine release from rat peritoneal mast cells in vitro. On a per ant basis, venom from S. invicta ( ed 50 = 0·12 venom reservoirs/ml ) was four times as potent as venom from S.

Safety and efficacy of fire ant venom in the diagnosis of fire ant allergy

Journal of Allergy and Clinical Immunology, 1992
Thirty-three adult patients who had had systemic allergic reactions to fire ant stings and 33 insect-nonallergic control subjects were skin tested with single lots of Solenopsis invicta (Sol i) fire ant venom (IFAV) and two commercially available imported fire ant whole body extracts (IFA WBEs).

51 Fire ant venom hypersensitivity

Journal of Allergy and Clinical Immunology, 1983
Abstract Levels of IgE antibody to fire ant whole body extract (FA-WBE) and fire ant venom (FAV) were evaluated in 60 patients with clinical histories of fire ant sting hypersensitivity and 11 frequently stung individuals without significant clinical reactivity to fire ant. An overlap of levels of IgE antibody to FA-WBE and FAV was seen between groups
