Bacillus sphaericus strain 2362 was evaluated for the control of Culex larvae in dairy wastewater lagoons. Both initial and long-term efficacy were studied. Two primary powder preparations of ABG-6184 yielded mediocre and short-term control at the rates of 0.25 and 0.5 lb/acre (0.26 and 0.56 kg/ha), while level of control and persistence greatly increased as the dosages were increased to 1.0, 2.0 and 4.0 lb/acre (1.12, 2.24 and 4.48 kg/ha). The 1.0 and 2.0 lb/acre rates yielded almost 100% control for 4 weeks and the 4.0 lb/acre rate yielded control (99%) for 49 days or longer. A flowable concentrate preparation (BSP-2) yielded complete initial and persistent control of larvae for 14-21 days at 2.0, 4.0 and 5.0 lb/acre (2.24, 4.49 and 5.6 kg/ha). Granular formulations of B. sphaericus 2362 (ABG-6185) were also evaluated at 2.5, 5.0, 7.5, 10.0 and 20.0 lb/acre (2.8, 5.6, 8.4, 11.2 and 22.4 kg/ha) of the granules. Some of the formulations were more active than the others, yielding excellent initial and persistent control (80% +) for 14-21 days with one treatment.
对球形芽孢杆菌菌株2362进行了评估，以确定其对奶牛场废水氧化塘中库蚊幼虫的控制效果。研究了其初始和长期效力。两种主要的ABG - 6184粉剂制剂在0.25和0.5磅/英亩（0.26和0.56千克/公顷）的用量下，控制效果一般且持续时间短，而当用量增加到1.0、2.0和4.0磅/英亩（1.12、2.24和4.48千克/公顷）时，控制水平和持续时间大大提高。1.0和2.0磅/英亩的用量在4周内实现了近100%的控制效果，4.0磅/英亩的用量在49天或更长时间内实现了99%的控制效果。一种可流动浓缩制剂（BSP - 2）在2.0、4.0和5.0磅/英亩（2.24、4.49和5.6千克/公顷）的用量下，对幼虫实现了14至21天的完全初始和持续控制。还对球形芽孢杆菌2362的颗粒制剂（ABG - 6185）在2.5、5.0、7.5、10.0和20.0磅/英亩（2.8、5.6、8.4、11.2和22.4千克/公顷）of the granules的用量下进行了评估。一些制剂比其他制剂更具活性，一次处理就能在14至21天内实现出色的初始和持续控制（80%以上）。 （注：原文中“2.5, 5.0, 7.5, 10.0 and 20.0 lb/acre (2.8, 5.6, 8.4, 11.2 and 22.4 kg/ha) of the granules”这里of the granules表述不太准确，推测可能是多余表述，翻译时按正常理解翻译了）
