Agriculture faces a critical paradox: while the global population requires a 60% increase in food production, traditional pest control methods are becoming unsustainable. Chemical pesticides, responsible for approximately 3 million cases of poisoning annually according to the WHO, are contaminating soils and water and impacting biodiversity. In this context, a revolutionary technology is emerging that could be a game-changer: sonogenetics.
Sonogenetics combines molecular genetics and bioacoustics to create a precise, targeted, and chemical-free pest control system. This technology uses specific sound frequencies to activate or deactivate genes in insect pests, offering a promising alternative to conventional pesticides.
What is Sonogenetics and How Does it Work?
The Scientific Principle
Sonogenetics is based on mechanotransduction—the ability of cells to convert mechanical stimuli (such as sound waves) into biochemical signals. Researchers have developed ultrasound-sensitive ion channels that can be inserted into specific cells of target organisms.
Mechanism of action:
- Genetic engineering: Genes encoding mechanosensitive proteins are inserted into the DNA of the insect pest.
- Acoustic exposure: Specific frequencies (generally ultrasound between 20-100 kHz) are emitted.
- Cell activation: The sound waves open specific ion channels.
- Physiological response: A specific behavior is triggered (repellency, sterility, or programmed death).
Unprecedented specificity
Unlike broad-spectrum pesticides, sonogenetics offers species-level specificity. This is achieved through:
- Specific delivery vectors: Modified viruses that infect only target species
- Specific frequencies: Each species has unique acoustic resonances
- Tissue promoters: Genes are expressed only in specific tissues
Practical Applications in 2025

Sonogenetics represents more than a new technology; it symbolizes a fundamental change in our relationship with agricultural ecosystems. By replacing chemical warfare against pests with management based on biophysical principles, we open the door to truly regenerative agriculture.
“The future of crop protection lies not in defeating nature, but in precisely modulating it. Sonogenetics gives us the tools to engage with the ecosystem instead of waging war against it.”
