Detection of Hidden Infestation of Cigarette Beetle <i>Lasioderma serricorne</i> F. in Turmeric Rhizomes by X-Ray Radiography

Abstract

An experiment was conducted to detect the hidden infestation of Lasiderma serricorne F. in the turmeric rhizomes by X-ray radiography. Six varieties viz., Duggirala, Pratibha, Armoor, Salem, Kasturi and Tekurpeta were selected based on their size. Standardization of X-ray radiography values were done by subjecting the fingers to 120 combinations of voltage (KV), current (mA) and exposure period (s). The results revealed that the hidden infestation was detected as accurately as possible with 22 to 25 KV voltage, 3 mA to 5 mA current with 10 sec of exposure.
