The chapter "Sex Pheromones and Their Impact on Pest Management" by Peter Witzgall, Philipp Kirsch, and Alan Cork reviews the significant advancements in pheromone research over the past five decades. Pheromones, species-specific chemicals that modify behavior, have been crucial in managing noxious insects in various sectors such as agriculture, horticulture, and forestry. The annual production of pheromone-based lures for monitoring and mass trapping is estimated to be in the tens of millions, covering at least 10 million hectares. These pheromones are effective at low population densities, do not harm natural enemies, and can reduce insect populations more sustainably than conventional insecticides. The authors emphasize the urgent need for sustainable insect control methods due to climate change, which is altering growing seasons and rainfall patterns. They advocate for interdisciplinary research involving chemists, entomologists, and plant protection experts to develop cost-effective solutions for global insect management, particularly in the context of food security and environmental sustainability. The chapter also highlights the historical development of pheromone research, from the discovery of the first sex pheromone in 1959 to the current understanding of insect olfactory systems and the molecular basis of pheromone communication.The chapter "Sex Pheromones and Their Impact on Pest Management" by Peter Witzgall, Philipp Kirsch, and Alan Cork reviews the significant advancements in pheromone research over the past five decades.
