Comparison of disinfection activities of nicotine with copper sulphate in water containing limnatis nilotica [Limnatis nilotica bulunan suda dezenfeksiyon amaçlı olarak nikotinin bakır sülfat İle karşılaştırılması]

In this study,we investigated the potential use of nicotine in controlling water polluted by leeches. the nicotine and copper sulphate lc50 values were also determined following 30 min exposure. the anti parasitic effect of nicotine was also compared with that of copper sulphate as positive control. the anti-leech effect of nicotine was evaluated against l. nilotica in which the number of dead and alive leeches in each utensil was counted for 30 min. the positive control group was copper sulphate and the negative control was distilled water. our data showed that the ld50 value for nicotine was 6/103 ppm with mean death time of 1.25±0.45 min while the ld50 value for copper sulphate was 637/102 ppm with a mean death time of 12.00±3.69 min. based on the obtained results nicotine is highly effective on leeches and might be used for disinfection purposes. © 2015,veteriner fakultesi dergisi. all rights reserved.
