| 摘 要： | 本文首次研究了苏云金杆菌油烟雾剂脉冲式烟雾载药技术。研究结果表明，Ｂｔ菌粉柴油烟剂经过６ＨＹ－２５型烟雾机后，仍保持活力；经纯化培养Ｂｔ对家蚕毒力没有下降；Ｂｔ烟雾直接对家蚕仍有致病力。经初步筛选，Ｂｔ油烟雾剂所用油以０号柴油为较好，Ｂｔ菌粉在Ｂｉｔ柴油烟雾剂中悬浮性好，烟雾化后Ｂｔ存活力高，且能自然扩散；食用植物油次之，而１００号汽油对Ｂｔ有杀伤作用，研究还发现，烟雾机喷药咀直径大小是影响Ｂｔ存

| Abstract: | This paper firstly reports the use of Bacillus thuringensis (Bt) aerosols in the pulse\|jet fogger to produce smog to kill insect pests.Bt in Bt aerosols still remains vigour on NB medium and virulence to silkworms.Among the three kinds of oil tested,diesel oil is the best one for Bt gemmae vigour,diffusion in smog,and suspensibility in the oil.In addition,the model of shower nozzle of pulse\|jet fogger is an important factor for Bt vigour.To sum up,the technique of Bt aerosols produced by pulse\|jet fogger is a new, simple and feasible way for the control of insect pests. |
