%X The effect of Ultraviolet (UV) rays on the activity of parasporal crystal of Bacillus thuringiensis, var. Kurstaki HD-1 strain was studied by SEM, SDS-PAGE, bioassay and other methods. It was found that the morphology and surface structure of PC were damaged ,and its solubility in alkaline solution or silkworm gut juice was decreased after being irradiated by UV, the solubility was lost completely after a long time irradiation over 5 hours, so the processed PC could not be degraded into protoxin with insecticidal activity and was denatured.
