Moths and other winged insects, and particularly their larva, can become a problem for farmers, often causing major damage to crops. Pesticides help alleviate the problem, but they have also been strongly criticized. Pheromones offer a sustainable alternative, albeit an expensive one. A new manufacturing technique is designed to reduce the costs of pheromones and make them competitive. In the EU project OLEFINE researchers at the Fraunhofer Institute for Building Physics IBP are dedicated to sustainability and Life Cycle Assessment.
