摘要

在本研究中,吡虫啉对鲤鱼胚胎(受精卵)和幼仔的毒性试验包括死亡率(%)、孵化成功率(%)和异常/畸形孵化率以及它们在有毒介质中的生长性能。通过Probit分析方法对吡虫啉急性毒性试验的报告数据进行统计分析,并且对C.carpio胚胎的48小时(小时)LC50报告为78ppm。选择三种亚致死剂量的吡虫啉,即7.8 ppm(T1)、15.6 ppm(T2)和23.4 ppm(T2),与对照一起进行进一步实验。研究结果表明,与对照组相比,暴露卵的死亡率(%)以剂量依赖的方式显著增加(p<0.05),孵化率(%)降低。同样,异常孵化率也随着农药浓度的增加而显著增加(p<0.05)。据报道,在不同的身体区域出现了各种类型的异常,如全长弯曲的身体、发育迟缓、孵化出的单眼、畸形的头部、尾部弯曲和变形的卵黄囊等。观察到的生长速率为孵化出的幼崽的长度增长(厘米)、体重增长(克)和体重增长百分比,随着农药浓度的增加,其含量也显著下降(p<0.05)。本研究结果表明,吡虫啉对幼仔的早期发育有显著影响,会导致畸形,并降低幼仔的生长速度。

The Toxicity of Imidacloprid on Early Embryonic Stages and Growth Rate of Hatchlings of Common Carp, Cyprinus carpio
In the present investigation, the toxicity of imidacloprid was tested on the embryos (fertilized eggs) and hatchlings of Cyprinus carpio in terms of mortality (%), hatching success (%) and abnormal/malformed hatchling along with their growth performance in toxicant medium. Reported data from acute toxicity tests of imidacloprid was statistically analyzed by Probit Analysis Method and 48 h (hour) LC50 was reported as 78 ppm for embryos of C. carpio. Three sublethal doses of imidacloprid i.e., 7.8 ppm (T1), 15.6 ppm (T2) and 23.4 ppm (T2), were selected for further experimentation along with control. The findings revealed that mortality of exposed eggs (%) was significantly (p<0.05) increased in dose dependent manner as a result hatching rate (%) was decreased as compared to control. Similarly, per cent of abnormal hatchling was also increased significantly (p<0.05) with increase in pesticide concentration. Various types of abnormalities has been reported in different body regions such as whole length curved body, stunted growth, hatchling with single eye, malformed head, flexure in the tail and deformed yolk sac etc. Growth rate was observed as length gain in centimeter (cm), weight gain in grams (g) and growth per cent gain in body weight of hatchling, which was also found to be declined significantly (p<0.05) with increase in pesticide concentration. The findings of the present investigation suggest that imidacloprid has significant effect on the early developmental stages, induces malformations and also decline the growth rate of hatchlings.
