Organisational immunity in social insects

Area of Science:

• Social insect behavior
• Epidemiology
• Network science

Background:

• Disease control is a significant selective pressure shaping insect societies.
• Social structures and interaction patterns within insect colonies can mitigate disease transmission.
• This collective defense mechanism is termed 'organizational immunity'.

Purpose of the Study:

• To review empirical evidence for organizational immunity in social insects.
• To describe individual-level behaviors contributing to collective disease resistance.
• To identify general properties of interaction networks that hinder pathogen propagation.

Main Methods:

• Review of existing empirical studies on social insects and disease transmission.
• Integration of epidemiological models and social network analysis.
• Analysis of individual behaviors and their impact on colony-level immunity.

Main Results:

• Organizational immunity can be both prophylactic (preventative) and induced upon pathogen exposure.
• Specific network structures and individual behaviors are identified that limit disease spread.
• Evidence supports the role of social organization in conferring disease resistance.

Conclusions:

• Social insects exhibit sophisticated organizational immunity, crucial for colony survival.
• Further research is needed to link theoretical models with empirical findings.
• Integrating individual and collective-level analyses is essential for a comprehensive understanding.
