Unlocking the Secrets of Insects: The Role of Mass Spectrometry to Understand the Life of Insects

Chemical signaling is crucial during the insect lifespan, significantly affecting their survival, reproduction, and ecological interactions. Unfortunately, most chemical signals insects use are impossible for humans to perceive directly. Hence, mass spectrometry has become a vital tool by offering vital insight into the underlying chemical and biochemical processes in various variety of insect activities, such as communication, mate recognition, mating behavior, and adaptation (defense/attack mechanisms), among others. Here, we review different mass spectrometry-based strategies used to gain a deeper understanding of the chemicals involved in shaping the complex behaviors among insects and mass spectrometry-based research in insects that have direct impact in global economic activities.
