Interplay between gut symbionts and behavioral variation in social insects

Area of Science:

• Behavioral Ecology
• Microbiology
• Insect Science

Background:

• Social insects display significant intraspecific behavioral variation.
• These insects commonly host specialized gut microbial communities.
• Emerging research indicates a link between insect behavior and gut microbiota.

Purpose of the Study:

• To explore the bidirectional relationship between gut microbiota and behavioral phenotypes in social insects.
• To discuss how intraspecific variation in gut microbiota composition influences social insect behavior.
• To examine how social insect behavior impacts their gut microbial communities.

Main Methods:

• Literature review and synthesis of recent studies.
• Analysis of existing data on insect behavior and microbial ecology.
• Conceptual framework development for the insect-microbe interaction.

Main Results:

• Insect behavioral phenotypes are influenced by gut microbiota composition.
• Gut microbiota composition is partly shaped by environmental and dietary exposures linked to behavior.
• Gut microbiota can modulate insect behavior, creating a feedback loop.

Conclusions:

• A dynamic, bidirectional interaction exists between gut microbiota and behavioral variation in social insects.
• Understanding this interplay is crucial for comprehending social insect ecology and evolution.
• Further research is needed to elucidate the specific mechanisms driving this relationship.
