Detection of insect infestation in an agricultural commodity is provided by piezoelectric means for generating electricity in response to vibration only of a frequency above about 500 Hertz, in vibrational communication with the agricultural commodity. The present invention may be utilized to detect infestation by a variety of different insects such as rice weevil, lesser grain borer, angoumais moth, in numerous types of agricultural commodities including corn, wheat, rice nuts, cotton, etc.. Various embodiments are disclosed including use of the piezoelectric means, on a probe, with a sample cup, in a device for telemetry, and with various container means for containing an agricultural commodity including e.g. a truck, ship, railroad car and storage bin such as a silo or grain elevator.
