2022年1月7日 · Most ant alkaloids function as venom, but some derive from other glands with alternative functions. They are used in defense (e.g., alarm, repellants) or offense (e.g., toxins) but also serve as antimicrobials and pheromones. We provide an overview of ant alkaloid diversity and function with an evolutionary perspective.

1987年1月1日 · This chapter provides an overview of the alkaloids in insects including ants and arthropods such as millipedes, spiders, scorpions, and centipedes; and describes biogenic amines, pigments, purines, tryptophan metabolites, and acyclic amines, some representatives of which are used for defenses and communications in arthropods.

2022年10月1日 · Venom alkaloids were found in crops and midguts of red imported fire ants. Alkaloids occurred at concentrations reported to be effective antimicrobial. Trophallaxis must be involved in the transfer of venom alkaloids. New queen provided alkaloids to …

Alkaloids in ants were first reported in the early 1970s and they have been reported in an increasing number of different ant groups, particularly as venom secretions (for a summary see Table 4). Although wasp venoms may contain amines and several other low molecular weight compounds, venom alkaloids seem to be a particularity of ants within ...

We provide an overview of ant alkaloid diversity and function with an evolutionary perspective.

1997年2月3日 · Chemical warfare in insects: Ants have a vast arsenal of chemical weapons for defense or to catch prey. Here the isolation and identification of a highly sensitive alkaloid, myrmicarin 663, which has an entirely novel carbon skeleton, is reported.

2021年10月22日 · Over a dozen different alkaloid classes have been reported from approximately 40 ant genera in five subfamilies, with peak diversity within the Myrmicinae tribe Solenopsidini. Most ant...

2023年7月3日 · The toxic piperidine alkaloids in fire ant venom have various biological functions and important ecological significance. In this work, we review patterns of venom use, as well as alkaloids’ chemistry, toxicities, potential applications, …

Here, using laboratory behavioral assays and analyses of videotaped interactions in South America, we report widespread venom detoxification among ants in the subfamily Formicinae. Across both data sets, nine formicine species, representing all major clades, used a stereotyped grooming behavior to self-apply formic acid (acidopore grooming) in ...

2024年10月10日 · Some alkaloids abundant in the venom of the red invasive fire ant (Solenopsis invicta), known as solenopsins, have garnered attention as potent inhibitors of bacterial biofilms, and there are no studies demonstrating such effects against fungal pathogens.
