Steering Soil Microbiomes to Suppress Aboveground Insect Pests

Area of Science:

• Plant-microbe interactions
• Soil microbiology
• Insect ecology

Background:

• Soil microbes influence plant traits and insect herbivores via molecular and chemical changes.
• Current research often overlooks the complexity of whole soil microbial communities (microbiomes).
• Understanding plant-insect interactions requires integrating aboveground and belowground research.

Purpose of the Study:

• To explore the role of whole soil microbiomes in plant-insect interactions.
• To propose holistic approaches for selecting soil microbiomes for plant protection.
• To bridge the gap between soil microbial ecology and plant-insect interaction studies.

Main Methods:

• Reviewing existing literature on soil-borne microbes, plant physiology, and insect herbivory.
• Conceptualizing the integration of soil microbiome complexity into plant-insect interaction research.
• Proposing novel strategies for microbiome selection based on plant protection efficacy.

Main Results:

• Soil microbiomes, not just single strains, significantly impact plant defense against herbivores.
• Holistic microbiome selection offers a promising avenue for sustainable pest management.
• Integrating microbiome complexity is crucial for advancing aboveground-belowground research.

Conclusions:

• The study highlights the potential of harnessing complex soil microbiomes for enhanced plant defense.
• Developing methods to select beneficial soil microbiomes is key to managing insect pests.
• This work calls for a paradigm shift towards a more integrated understanding of soil-plant-insect systems.
