A multinational team of researchers has developed a less expensive method to produce pheromones, a potential crop pest repellent, by genetically modifying a camelina plant to produce pheromones used by two types of moths. These pheromones, when applied, successfully confused the pests in agricultural test sites, showing effectiveness similar to commercially-made pheromones but at a much lower cost. The findings, published in the journal Nature Sustainability, highlight a significant advancement in safer, cost-effective pest management strategies.
