Alkaloids in the venom of Messor ants
Biochemical Systematics and Ecology, 2006Tobacco alkaloids of the anabasine type have been found or confirmed in the venom of five species of arid-dwelling Messor ants. They are frequently accompanied by alkylpyrazines. Messor mediorubra contains four alkaloids, with anabasine the major component and also minor pyrazines.

Proteomic analysis of Myrmecia pilosula (jack jumper) ant venom
Toxicon, 2006 Ant sting allergy in Australia is predominantly due to the Myrmecia pilosula species complex. Gel separation of M. pilosula venom is necessary so that the allergenic importance of each component can be defined by western blotting.

Venom and Venom Apparatus of the Bull Ant, Myrmecia gulosa (Fabr.)
Science, 1964The venom of Myrmecia gulosa (Myrmeciinae, Formicidae) is of a proteinaceous type and is separated by electrophoresis into eight components. The venom contains histamine, a hyaluronidase, and a direct hemolytic factor. It also shows kinin-like activity.

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, 1990New 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.

Journal of Pharmaceutical and Biomedical Analysis, 2008 Ant sting allergy is relatively common within south-eastern Australia and is predominantly due to Myrmecia pilosula (Jack Jumper Ant, JJA). Venom immunotherapy has been shown to be effective in preventing anaphylaxis to the sting of the JJA, but ...

Ant Venoms: A Study of Venom Diversity
1978Ant venoms appear to represent an almost untapped reservoir of information capable of adding several exciting chapters to the story of toxinology. Ants share with some bees and wasps the distinction of being the only truly social group of venomous animals. This fact implies that most of the venomous individuals belong to an essentially sterile class of

Pyridine Alkaloids in the Venom of Imported Fire Ants
Journal of Agricultural and Food Chemistry, 2019Venomous 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 ...
