摘　　要：在对颤蚓类"红虫"开展了大量生物学研究和成虫灭活研究的基础上,研究了不同温度下,液氯、氯胺、二氧化氯和高锰酸盐复合药剂等4种消毒剂,在一定时间内对颤蚓类"红虫"幼虫和虫卵的灭活效果。结果表明,在相同条件下消毒剂对颤蚓类"红虫"幼虫的灭活作用较显著,而对颤蚓类"红虫"蚓茧的灭活效果则很不理想。4种消毒剂在各个时间点的灭活率大体上都随其浓度的升高而增大,每个浓度下的灭活率也随接触时间的延长而上升。Based on the biological research and imago inactivation research of bloodworms （ Tubi- fex species）, the inactivation effect of four disinfectants on Tubifex larvae and eggs at various temperatures were studied. These disinfectants include liquid chlorine, chloramine, chlorine dioxide, and permanganate. It is found that under the same conditions, the disinfectants have significant inactivation effect on Tubifex larvae, and no inactivation effect on Tubifex cocoons. The inactivation rates at different times are increased with increasing concentrations and contact times of the disinfectants.
