Russian researchers from PSU used fiber optic acoustic sensors to determine the location of cockroaches and record the sounds they make. The experiment will significantly speed up the development of methods for early detection of insect pests in agriculture.
Specialists "listened" to the Madagascar hissing cockroach, which remained unharmed after the study.
The study opens up the potential of fiber optic technology for early detection of pests in agriculture by their acoustic traces and for tracking changes in the ecosystem.
The Madagascar cockroach is a convenient model for scientific experiments. It reaches a length of 10 cm and has no wings. The insect makes hissing sounds in a wide frequency range. This is an ideal object for acoustic research.
The slow movements of the cockroach were difficult to detect without additional processing. According to scientists, the system successfully recorded the hissing sounds and the physical contact of its legs with the fiber during rapid movement.
Previously, specialists were able to record the sounds of the vital activity of colonies of palm weevil larvae, but the application of the method for detecting individual insects outside the wood was a new direction.
The approach we have demonstrated can significantly increase the effectiveness of such studies, contributing to the wider field of bioacoustics and environmental monitoring.
