&NA; Fire ant venom contains insecticidal alkaloids named ‘solenopsins’. Whilst species‐specific differences are reported, little attention has been given to caste‐specific venom adaptations. The venom of fire ant queens has remained particularly poorly studied, though studies have shown it to be strikingly similar across different species, in being primarily composed of the alkaloid isosolenopsin A, regardless of the chemical configuration in workers. We predict that this is the evolutionary… Expand
Venom Function of a New Species of Megalomyrmex Forel, 1885 (Hymenoptera: Formicidae)
A new species of free-living Megalomyrmex ant is described and its singular venom alkaloid (trans-2-butyl-5-heptylpyrrolidine) is identified and the antibiotic and insecticidal functions of its venom are elucidated. Expand
Chemical blueprints to identifying fire ants: overview on venom alkaloids
A set of chemical tools to facilitate species diagnosis from field-collected fire ant samples are introduced, herein focusing on minor workers, to help researchers working on fire ants in future studies. Expand
Prevalence and management of Solenopsis invicta in China
The two-step method of combing toxic baits and contact dust emerges as the forefront method crucial in managing S. invicta, thereby causing negative impacts on the abundance, diversity, and richness of native arthropod communities. Expand
Comparing mechanisms of competition among introduced and resident ants in China: from behavior to trophic position (Hymenoptera: Formicidae)
Invasive ant species interact with both native and previously introduced ants in new environments. Their effects on resident species may vary warranting a careful examination of the possibleExpand
Interspecific Eavesdropping on Ant Chemical Communication
Current knowledge about how ant chemical communication systems can be exploited by unintended receivers is reviewed and future research is proposed that will improve the understanding of community assembly by examining host traits that influence their susceptibility to eavesdropping associates.

The Biochemistry, Toxicology, and Uses of the pharmacologically active phytochemicals: Alkaloids, Terpenes, Polyphenols, and Glycosides
The research focused on the biochemistry and the medicinal uses of alkaloids, terpenes, polyphenols, and glycosides. Several parts of plants such as bark, root, leaf, stem, etc. are being used toExpand


The Biochemical Toxin Arsenal from Ant Venoms
The present review details the unique structures and pharmacologies of known ant venom proteinaceous and alkaloidal toxins and their potential as a source of novel bioinsecticides and therapeutic agents. Expand
Workers and alate queens of Solenopsis geminata share qualitatively similar but quantitatively different venom alkaloid chemistry
The cis and trans alkaloids from body extracts of workers and alate queens of S. geminata were separated by silica gel chromatography, identified, and quantitated by GC-MS analysis, and the possibility that differences in venom chemistry could be correlated with this displacement is explored. Expand
Lethality of Red Imported Fire Ant Venom to Argentine Ants and Other Ant Species
S. invicta venom is less toxic to fire ants while being just as toxic to Argentine ants as the simpler, more primitive venom of S. xyloni, which may explain the superior interference competition shown by the red imported fire ant. Expand
Biochemical evolution in fire ant venoms
The distribution of 2,6-dialkyl(and alkenyl-)piperidine alkaloids in the venom of fire ant workers of Solenopsis xyloni, S. geminata, and S. richteri has been compared with the occurrence of these compounds in the Venom of alate queens of the same species, leading to the proposal that the venoms of S. invicta are more highly evolved.

Intraspecific and intracolonial variation in the profile of venom alkaloids and cuticular hydrocarbons of the fire ant Solenopsis saevissima smith (Hymenoptera: Formicidae)
The present study is the first to report intraspecific variation in some chemical characters, namely, cuticular hydrocarbons and venom alkaloids, within the Brazilian fire ant species Solenopsis saevissima and also reports on within-nest variations among members of different castes. Expand
A simple, rapid method for the extraction of whole fire ant venom (Insecta: Formicidae: Solenopsis).
This work presents a simple and fast method of obtaining whole venom compounds from large quantities of fire ants, and shows that this approach yields the same proteins obtained by other authors using less efficient traditional methods. Expand
Chemical Warfare Among Invaders: A Detoxification Interaction Facilitates an Ant Invasion
The capacity to detoxify a major competitor’s venom probably contributes substantially to its ability to displace S. invicta populations, making this behavior a causative agent in the ecological transformation of regional arthropod assemblages. Expand
Inability of Incipient Solenopsis invicta (Hymenoptera: Formicidae) Colonies to Establish in a Plot with a High Density of Solenopsis (Diplorhoptrum) Colonies
The results suggest that high density of at least one species of native ant can eliminate or at least reduce the establishment of small colonies of S. invicta that may have started to develop after the escape of the founding queen. Expand
Fire ant venoms: intraspecific and interspecific variation among castes and individuals.
Results obtained on one colony of S. geminata soldiers suggested that these individuals may have arisen from at least two fertile queens in the nest, and a fair degree of control of the biosynthetic system for these 2,6-disubstituted piperidine alkaloids is exhibited. Expand
Colony Founding by Queens of the Red Imported Fire Ant, Solenopsis invicta
The method by which newly mated queens of the red imported fire ant, Solenopsis invicta Buren, found new colonies was investigated and optimum temperature was found to be between 27.5 and 32°C. Expand
