A team of specialists from the Institute of Agricultural Research (INIA) Quilamapu, in Chillán (Ñuble Region) develops non-chemical tools for agricultural pest control.

This project, led by the researcher of the Laboratory of Chemical ecology from INIA, Dr. Ricardo Ceballos, uses the chemical ecology to modify insect behavior through natural signals.

“Chemical ecology” seeks to 'trick' insects into perceiving an environment that does not actually exist", Ceballos explained.

This approach allows pests to be managed in a targeted manner, affecting only the target species without negatively impacting the the environment nor in other organizations.

The work focuses on the use of semiochemicals, natural compounds such as pheromones, which interfere with the behavior of insects.

According to the researcher, these methods are more effective in pests that are difficult to manage, such as those that attack estate y stems, where pesticides do not reach effectively.

New alternatives to chemicals

Currently, specialists are evaluating different attractants in commercial orchards of blueberries to control the apple tree saw, a pest that causes severe structural damage to plants.

“We are conducting field tests to define the effectiveness of these attractants and We hope to have a product ready for implementation in the coming seasons.“, Ceballos added.

The research also includes the use of vegetable extracts y essential oils as attractants or repellents.

These compounds are designed to control insects at different stages of their life. Lifecycle, like larvae.

“This process requires a large investment of time and resources, but it responds to the growing demand for gluten-free foods. chemical waste", the researcher highlighted.

In addition, the project addresses the control of other relevant pests, such as vine donkey and brown fruit bug.

According to Ceballos, the identification of specific compounds It is an essential task to develop innovative solutions that enable more sustainable agricultural production.
