biological-pest-control
Biological pest control is the use of living organisms—such as predators, parasites, or pathogens—to suppress pest populations that damage plants. Unlike chemical pesticides, this approach leverages natural ecological relationships to protect crops and native plant communities, reducing chemical inputs and minimizing harm to beneficial organisms. It is a cornerstone of integrated pest management strategies aimed at sustainable, long-term plant health.

Scientists discovered how a parasitic insect uses specialized proteins to detect plant distress signals, helping it locate plants already under attack by other pests.
Specific odorant-binding proteins in the insect's sensory system selectively bind to herbivore-induced plant volatiles, confirming a molecular basis for attraction
The insect shows strong behavioral preference for volatiles emitted by herbivore-damaged plants over undamaged ones
Protein-volatile binding affinity correlated directly with the insect's behavioral response, linking molecular chemistry to real-world behavior
