What is Insect Microbiota?

Insect microbiota refers to the microbial communities residing in insect guts, exhibiting diversity in structure and function that supports host nutrition, pathogen resistance, and environmental adaptation (Engel and Moran, 2013).

Studies characterize gut bacteria in social insects like honey bees and termites using 16S rDNA sequencing. Key papers include Engel and Moran (2013, 2502 citations) on diversity and Engel et al. (2012, 904 citations) on honey bee functional roles. Over 10 papers from 2012-2022 exceed 400 citations each.

Key Challenges

Why It Matters

Insect microbiota influences pollinator health amid pesticide exposure and habitat loss, as antibiotic perturbations elevate honey bee mortality (Raymann et al., 2017, 532 citations). Gut bacteria promote weight gain via metabolism and hormonal signaling (Zheng et al., 2017, 647 citations), aiding colony survival. Termite microbiota enables lignocellulose digestion critical for ecosystem decomposition (Brune and Dietrich, 2015, 389 citations). Climate stress exacerbates microbiota disruptions, threatening biodiversity (Harvey et al., 2022, 499 citations).

Key Research Challenges

Microbiota Perturbation by Antibiotics

Antibiotics disrupt honey bee gut communities, increasing mortality from opportunistic pathogens (Raymann et al., 2017). Restoring microbiota post-exposure remains unresolved. Engel et al. (2012) highlight core phylotypes vulnerable to such shifts.

Linking Microbes to Host Fitness

Bacteria contribute to weight gain and gene expression in bees, but causal mechanisms need clarification (Zheng et al., 2017). Metabolic functions vary by species phylotype (Kešnerová et al., 2017). Social transmission complicates controlled studies.

Environmental Stress Effects

Climate change alters microbiota composition, amplifying pathogen webs in collapsing colonies (Harvey et al., 2022; Cornman et al., 2012). Pesticides and habitat loss challenge plasticity in non-model insects. Termite guts show evolutionary divergence under ecological pressures (Brune and Dietrich, 2015).
