Abstract Necrophoric behaviour is critical sanitation behaviour in social insects. However, little is known about the necrophoric responses of workers towards different developmental stages in a colony as well as its underlying mechanism. Here, we show that Solenopsis invicta workers display distinct necrophoric responses to corpses of workers and pupae. Corpses of workers killed by freezing (dead for <1 h) were carried to a refuse pile, but pupal corpses would take at least 1 day to elicit…

Mortality of Solenopsis invicta Workers (Hymenoptera: Formicidae) After Indirect Exposure to Spores of Three Entomopathogenic Fungi
- Biology, MedicineJournal of insect science

Mortality caused by indirect exposure to Metarhizium brunneum and Beauveria bassiana to the red imported fire ant, Solenopsis invicta Buren, workers was evaluated and confirmed that fungal spores infected workers while walking on the treated paper.

Behaviours indicating cannibalistic necrophagy in ants are modulated by the perception of pathogen infection level
- BiologyScientific reports
- 2020
The results showed that the ants distinguished between corpses of different types and with different levels of infection risk, adjusting their behaviour accordingly, and the frequency of behaviours indicating cannibalistic necrophagy increased during starvation, although these behaviours seem to be fairly common in F. polyctena even in the presence of other food sources.
Differential Behavioral Responses of Solenopsis invicta (Hymenoptera: Formicidae) Workers Toward Nestmate and Non-Nestmate Corpses

Abstract The removal of corpses (aka ‘necrophoric behavior’) is critical to sanitation in ant colonies. However, little is known about differences in the necrophoric responses of Solenopsis invicta…
Linoleic acid as corpse recognition signal in a social aphid
- BiologyZoological letters
- 2022
The commonality of the death pheromones across the divergent social insect groups highlights that these unsaturated fatty acids are generally produced by enzymatic autolysis of cell membranes after death and therefore amenable to utilization as a reliable signal of dead insects.
Comparison of Twelve Ant Species and Their Susceptibility to Fungal Infection
- BiologyInsects
- 2019
Survival after fungal exposure in 12 species of ants is studied and the possible importance of the metapleural gland is discussed, and how the secondary loss of this gland in the genus Camponotus could favor a stronger behavioral response against pathogen threats.
Pathogen prevalence modulates medication behavior in ant Formica fusca
- MedicinebioRxiv
- 2022
It is seen that workers of F. fusca engage in self-medication behavior even if exposed to a low lethal dose of a pathogen, and that the strength of that response is affected by the prevalence of the disease in the colonies, which affirm the ability of ants toSelf-medicate against fungal pathogens, shed new light on plasticity of self- medication and raise new questions to be investigated on the role self-Medication has in social immunity.
A death pheromone, oleic acid, triggers hygienic behavior in honey bees (Apis mellifera L.)
- BiologyScientific Reports
- 2018
A picture is painted of the molecular mechanism behind hygienic brood-removal behavior, using odorants associated with freeze-killed brood as a model, and it is suggested that the volatile β-ocimene flags hyGienic workers’ attention, while oleic acid is the death cue, triggering removal.
Destructive disinfection of infected brood prevents systemic disease spread in ant colonies
- BiologybioRxiv
- 2017
This study investigated how ants prevent disease outbreaks following the successful infection of their brood with a fungal pathogen and found that the ants can detect lethal infections early in the non-infectious incubation period of the pathogen’s lifecycle, using chemical ‘sickness cues’ expressed by the infected pupae.

Aspects of Necrophoric Behavior in the Red Imported Fire Ant, Solenopsis Invicta

Corpse-bearing ants show stereotyped behavior upon encountering refuse piles and adding their burden to it, and there is a positive relationship between slope and the presence of refuse piles, and these are located downhill from the mound.
Chemical signals associated with life inhibit necrophoresis in Argentine ants
- BiologyProceedings of the National Academy of Sciences

It is demonstrated how the cuticular chemistry of Argentine ant workers, Linepithema humile, undergoes rapid changes after death, which supports an alternative mechanism of ant necrophoresis in which the precise recognition and rapid removal of dead nestmates are elicited by the disappearance of these chemical signals associated with life.

Ants of the Australian and New Caledonian genus Myrmecia apparently include the most archaic living Formicidae, and species of MyRMecia may well illustrate the earliest patterns of Formicid social organization, and embody themost archaic patterns offormicidsocial behavior, that are likely to be able to study in detail in the laboratory or the field.

The chemical content of whole body surface extracts of adult queens of different developmental and reproductive stages and of adult workers from monogyne and polygyne forms of the fire ant Solenopsis invicta found that the composition of the most abundant components, venom alkaloids, differed between queens and workers, as well as between reproductive and non-reproductive queens.

The results suggest that the oleic acid serves as a corpse recognition signal and is generated by enzymatic hydrolysis of triglyceride, with the enzyme activated after death.
