The search for more sustainable methods for food production has made a new advancement thanks to the work of researchers from the Polytechnic University of Valencia (UPV) and the Spanish National Research Council (CSIC). The team developed an innovative technique to produce insect pheromones more efficiently and economically.
This scientific progress could transform the way agricultural pests are managed. Instead of relying on chemical pesticides, the proposal leverages natural chemical signals used by insects to communicate and reproduce.
Moreover, the new methodology would significantly reduce the costs associated with pest control, facilitating its adoption in agricultural operations of various scales and contributing to a more environmentally friendly production.
How pheromones work in biological control
Pheromones are chemical compounds emitted by insects to transmit information to individuals of the same species. Among their most important functions is the attraction of mates during reproduction.
Through the artificial synthesis of these substances, specialists can alter pest behavior. On one hand, it is possible to attract insects to specific traps; on the other, it can hinder the meeting between males and females, thus reducing reproduction.
In this way, it is possible to reduce the population of harmful insects without releasing toxic substances into the environment. As a result, it protects biodiversity and avoids affecting beneficial organisms such as bees, butterflies, and other pollinators.
A more economical and efficient process
One of the main obstacles to the mass use of pheromones was their high production cost. However, the new method developed by the Spanish researchers optimizes the synthesis processes and uses more accessible materials.
Thanks to this technological improvement, the production of pheromones can be done with lower energy consumption and in less time. Studies indicate that the final cost could be reduced by up to 60% compared to conventional systems.
Additionally, the obtaining of high-purity compounds facilitates their application on a large scale. This opens new opportunities for producers to incorporate integrated pest management tools with less environmental impact.
Other ways to protect crops without resorting to pesticides
The use of pheromones is part of a wider set of sustainable agricultural strategies. Among them, biological control stands out through predatory or parasitoid insects that naturally regulate pest populations.
Additionally, crop rotation helps to disrupt the biological cycles of insects and diseases, while associated crops promote ecological diversity and reduce the vulnerability of production systems.
On the other hand, the use of physical barriers, chromatic traps, resistant varieties, and agroecological management practices allows for reducing dependency on chemical products. These alternatives strengthen soil health, preserve water quality, and promote more resilient agricultural ecosystems in the face of climate change.
Benefits for the environment and food production
The adoption of synthetic pheromones represents an opportunity to move towards a more balanced agriculture between productivity and environmental conservation. By reducing pesticide application, it decreases contamination of soils, watercourses, and food.
Moreover, this technology helps preserve key species for agricultural ecosystems, especially pollinators and other organisms that perform essential ecological functions.
Finally, the development driven by the UPV and the CSIC aligns with international trends promoting sustainable food systems. The combination of scientific innovation, cost reduction, and environmental protection could make pheromones a central tool for the agriculture of the future.
