二化螟是黑龙江地区水稻主要害虫之一。由于长期使用化学农药，水稻二化螟对化学农药产生了抗药性，不仅用药效果明显下降，而且对黑龙江大米的品质产生了影响。为了筛选出可以替代化学杀虫剂的生物农药，选用100亿孢子/mL短稳杆菌悬浮剂与8000 IU/mg苏云金杆菌可湿性粉剂进行对照，对二化螟进行了药效试验。试验结果表明：100亿孢子/mL短稳杆菌悬浮剂1500 mL/hm2对二化螟的防治效果最好，且对水稻、对人、畜、禽及其他非靶标生物都安全，极具推广应用价值。

Rice-stem borer is one of the main pests of rice in Heilongjiang Province, China. Because of using chemical pesticides for a long time, the rice-stem borer had produced resistance to chemical pesticides, which not only caused the control efficacy to decrease significantly, but also impacted the rice quality in Heilongjiang. In order to choose the biological pesticides to replace the chemical pesticides, a test was conducted by using suspending agent of 10 billion spores/mL of Empedobacter brevis for rice-stem borer control, with the wettable powder of 8 000 IU/mg Bt as the control insecticide. The results indicated that using 1 500 mL of the Empedobacter brevis in every hm2 rice fields had the best control efficacy, and was safe to rice, people, livestock, birds and other non-target organisms. So this fungicide had development and application values.
