将舞毒蛾核多角包含体原料制作成粉末药剂和水的悬浮液药剂,在不同的条件下贮存了不同的时间。各种 PIB’s(即核多角包容体——译者)制剂都经受了室温或升高的温度及冷藏或冻结等条件作用的试验。悬浮液药剂的毒效在冷藏条件下能保持5年之久,即使在室温条件下也能保持2年。在空气中晾干的粉末药剂,在4℃条件下存放一年之后才逐渐失去其毒性。空气中晾干的粉末药剂和悬浮液药剂在38℃条件下都要保存6个月之后才丧失其毒性。
The Gypsy moth nuclear polyhedron inclusion body material was made into a powder medicament and water suspension agent, stored under different conditions for different time. Various PIB’s formulations have undergone tests at room or elevated temperatures and conditions such as refrigeration or freezing. The toxicological effects of the suspension agent can be maintained for five years under refrigerated conditions, even for two years at room temperature. Powder agents that dry in air lose their toxicity gradually after one year of storage at 4 ° C. Airborne dry powder medicaments and suspensions are not toxic until they are stored for up to 6 months at 38 ° C.
