| Abstract | ||
| This search aimed to study the toxicity effects of Colti 5 pesticide on water flea Daphnia pulex age 24 h by determined lethal concentration that killed half number of treated Daphnia (LC50) after 48 h from exposure, after using serial concentrations between (0.01-0.07) mg/l, and try to appear the effects of pesticide on formation of reproductive characteristics of Daphnia after 21 days from exposure to concentrations between (0.01-0.03) mg/l. The results showed that the LC50 was (0.032) mg/l, and the pesticide was decreased from produce individuals with increasing concentration. Also the results showed there was a significant correlation coefficient between the concentrations and percentage of mortalities and between the concentrations and number of individuals that not produce sac of eggs. | ||
