【Abstract】 Polyhedral inclusion bodies of nuclear polyhedrosis virus (NPV) of poplar looper Apocheima cinerarius, were stored as dried powder and formulations under various conditions and for various lengths of time. The dry polyhedral powder made by the viral precipitation with acetone from lactose suspensions and its preparing formulations were stored at room temperatures, or in refrigerator (4 ℃) or in freezing (-20 ℃).The results indicated that the viral activity of the dry polyhedral powder (AciNPV) and the formulations could be retained for two years in refrigerator (4 ℃) or in freezing ( - 20℃). Dry powder stored at room temperature could only retain its viral activity for one year. The formulation of AciNPV stored at room temperature showed a better result that it was fairly stable for nearly two years.更多还原
