Abstract
Monitoring Insect Pheromones in Real Time
This study explores the use of SESI-HRMS and portable membrane inlet mass spectrometry for the rapid detection and monitoring of insect sex pheromones. By measuring pheromone levels in the gas phase, these technologies can support more precise pest management strategies, helping verify pheromone coverage, identify gaps, and optimize reapplication in mating disruption programs. The work demonstrates sensitive detection from low ppt to low ppb levels, fast response times, and successful identification of key pheromone components in real Plutella xylostella headspace samples, highlighting a promising path toward real-time and field-deployable pheromone monitoring.
