How do ants clean themselves?

Introduction

Ants exhibit a variety of cleaning behaviors to maintain hygiene and prevent infections within their colonies. These behaviors are crucial for their survival, as they help in removing contaminants and pathogens from their bodies and environment. The cleaning mechanisms range from physical grooming to the application of antimicrobial substances.

Key Insights

Allogrooming and Chemical Disinfection:
- Ants engage in allogrooming, where they clean each other to remove infectious particles. This behavior is enhanced by the application of formic acid, which acts as a chemical disinfectant to inhibit fungal growth .
Antenna Cleaning:
- Ants use specialized structures on their legs to clean their antennae, which are essential for sensory functions. The cleaning involves clamping the antenna between a notch and a spur on the leg and pulling it through, followed by cleaning the cleaning apparatus with their mouthparts .
Sanitary Care and Social Immunity:
- Ants perform sanitary care by grooming and applying antimicrobial substances to contaminated nestmates. This behavior reduces the risk of disease spread within the colony and includes risk-adjusted care to avoid superinfections .
Destructive Disinfection:
- When ants detect lethal infections in their brood, they perform destructive disinfection by biting the infected pupae and applying antimicrobial poison internally, effectively killing the pathogen and preventing its spread.
Mutualistic Cleaning Behaviors:
- In mutualistic relationships, such as with the pitcher plant Nepenthes bicalcarata, ants clean the plant's surfaces to enhance prey capture efficiency. This cleaning behavior also prevents fungal contamination, benefiting both the ants and the plant.
Seed Cleaning:
- Ants clean seeds by removing fruit pulp, which protects the seeds from fungal infections. This behavior not only involves physical cleaning but also the application of antifungal substances.
Waste Management:
- Ants manage waste by discarding it outside the nest, especially when it is contaminated with pathogens. The presence of brood enhances the hygienic responses of workers, leading to more efficient waste removal.

Conclusion

Ants employ a range of cleaning behaviors to maintain hygiene and prevent infections within their colonies. These behaviors include allogrooming with chemical disinfection, specialized antenna cleaning, sanitary care, destructive disinfection of infected brood, mutualistic cleaning with plants, seed cleaning, and efficient waste management. These strategies collectively contribute to the social immunity of ant colonies, ensuring their survival and health.

Antenna Cleaning Is Essential for Precise Behavioral Response to Alarm Pheromone and Nestmate–Non-Nestmate Discrimination in Japanese Carpenter Ants (Camponotus japonicus)

Self-grooming of antennae in Japanese carpenter ants is essential for maintaining their ability to perceive alarm pheromones and discriminate between nestmates and non-nestmates.

Destructive disinfection of infected brood prevents systemic disease spread in ant colonies

Destructive disinfection of infected brood by ants acts as a second line of defense against disease in ant colonies, preventing systemic disease spread and allowing the colony to maintain its social immunity.

Functional morphology and efficiency of the antenna cleaner in Camponotus rufifemur ants

The antenna cleaner in Camponotus rufifemur ants effectively removes over 60% of contaminants with the first stroke, acting like a series of sieves to remove larger particles first.

Seed cleaning behavior by tropical ants and its anti-fungal effect

Ants' seed cleaning behavior in tropical forests protects seeds from fungus infection, suggesting the need for anti-fungal substances on fruit pulp and seed surfaces.

Ants avoid superinfections by performing risk-adjusted sanitary care

Ants can reduce their own risk of superinfection by performing risk-adjusted sanitary care, reducing the risk of contracting infections while caring for contagious individuals.

Active use of the metapleural glands by ants in controlling fungal infection

Ants selectively groom their metapleural glands when facing fungal infection, suggesting they selectively use their secretions to control fungal infection.

Waste management by ants: the enhancing role of larvae

Ants can detect pathogenic waste and discard it faster, with larvae playing a crucial role in enhancing hygienic responses and sanitary control within the colony.
