Comprehensive Collection, Detection, and Identification of Insect Pest-Induced Crop Volatiles for Advanced Pest Management.

Abstract

Plants emit a diverse array of volatile organic compounds in response to stress. These volatiles serve as a defense mechanism against various stressors. Highly dynamic and chemically reactive, plant volatiles readily interact with other atmospheric gases, often transforming into distinct molecular forms. The precise detection of herbivore-induced plant volatiles at high purity is a fundamental prerequisite for translating scientific insights into actionable strategies. This process encompasses a series of meticulously coordinated steps, ranging from the selection of appropriate plant specimens to the quantification of their volatile emissions. While standardized protocols for the accurate estimation of plant volatiles are well established, the advancement of volatome research remains constrained by limited knowledge regarding the functional characterization of these plant volatiles. This study presents a detailed account of multiple procedures for the collection and characterization of plant volatiles, utilizing a locally engineered and specially designed volatile trapping apparatus, with particular emphasis on the critical, often subtle, procedural nuances involved.
