Chemically mediated multitrophic interactions and their role in crop protection.

Area of Science:

• Agricultural Science
• Ecology
• Biochemistry

Background:

• Biotic stresses, particularly insect pests, significantly limit agricultural production.
• Multitrophic interactions (MTIs) involving plants, pests, natural enemies, and pollinators are crucial for agroecosystems.
• Microbial activity and specialized metabolites heavily influence MTIs in agricultural settings.

Purpose of the Study:

• To review the role of plant- and microbial-derived specialized metabolites in mediating MTIs.
• To explore the application of these metabolites in sustainable crop protection.
• To identify knowledge gaps and recent advances in developing innovative crop protection technologies.

Main Methods:

• Literature review synthesizing current research on specialized metabolites and MTIs.
• Analysis of chemically mediated mechanisms in pest, natural enemy, and pollinator interactions.
• Examination of plant defense priming and microbial influences.

Main Results:

• Specialized metabolites, often mediated by microbial activity, are key drivers of MTIs in agriculture.
• These metabolites influence attraction/repellence of pests and beneficial insects, and plant defense.
• Understanding these chemical cues offers novel avenues for sustainable pest management.

Conclusions:

• Plant- and microbial-derived specialized metabolites are vital for mediating MTIs in agroecosystems.
• Harnessing these chemical interactions presents significant opportunities for developing sustainable and ecologically sound crop protection strategies.
• Further research into these mechanisms will drive innovation in pest management technologies.
