目的　了解苏云金杆菌以色列变种 (B.t.i H- 14)剂型与拟除虫菊酯类杀虫剂混配后的稳定性。方法　将B.t.i H - 14与杀虫剂混合于玻瓶内 ,存放于夏秋季室温 ,每隔 30天取出一次直至 12 0天 ,检测杀虫剂和 B.t.i H- 14含量的变化。结果　三组间比较 ,存放时间相同但粉剂组杀虫剂和 B.t.i H- 14含量减少最少。结论　 B.t.i H- 14与化学杀虫剂以粉剂混配存放 ,稳定性良好 ,可作为混配杀虫剂试验选用剂型。

Objective To understand the stability of Bacillus thuringiensis mixed variant (B.t.i H-14) with pyrethroid insecticides. Methods The mixture of B.t.i H - 14 and insecticide was placed in glass bottle and stored at room temperature in summer and autumn. It was taken out every 30 days until 120 days. The changes of insecticides and B.t.i H - 14 contents were examined. Results Among the three groups, the storage time was the same but the content of pesticides and B.t.i H-14 in the powder group was the least. Conclusion B.t.i H-14 and chemical insecticides were mixed with powder storage, good stability, can be used as a mixed pesticide test dosage form.
