蜂乐1号烟剂是一种最近研制成功的新型杀蜂螨药剂,其有效成分为溴螨酯.经室内外试验结果,对蜂螨有较强杀伤力,对蜜蜂十分安全.烟剂中的溴螨醋对雅氏大蜂螨的LC_(50)为0.26克/米~3,LC_(95)为2.92克/米~3 对蜜蜂则分别为71.45克/米~3和218.70克/米~3,二者分别相差274.8倍和74.9倍.一平箱蜂群一次用含0.45克有效成分的药,对蜂体上大蜂螨的防除效果平均93%以上.对蜂群每隔5天施药一次,经3次施药后蜂群状况正常.在施药3次后对所取蜜样进行检测,其中溴螨酯的残留量远远低于联合国粮农组织所规定的参考限量.该烟剂适于在蜂箱外施药,比目前国内一般的开箱施药方法提高工效15倍以上,更适用于许多过去不便用药的场合.
