Abstract
Detection of pheromones is pivotal to chemical ecology and agronomy; however, analytic detection of the volatile pheromone components from odorized air is highly challenging. Here, we introduce a protocol for the detection of airborne pheromones from female moths, which are key models for chemosensory studies. We describe a step-by-step guide from pheromone collection to quantitative estimation of pheromone components. We also detail procedures for gas chromatography-mass spectrometry (GC-MS) analysis. This protocol has potential applications beyond chemosensory research, particularly in environmental chemistry. For complete details on the use and execution of this protocol, please refer to Ghosh et al.(1).
