| Abstract This study Experiment was conducted in the laboratory of microbiology/ College of Veterinary Medicine/ AL-Qasim Green University. This study aimed to evaluate the effect of Topsin fungicide on larvae phases of Culex pipiens mosquitoes after exposure to different concentration from it then calculated the approximately value of LC50 after exposure to different concentration (20-60)mg/l of Topsin. The results showed that the larval mortalities were (20 - 66.64%, 16.67- 49.68%, 9.91- 39.57% and 10.2- 48.86%) to the first, second, third and forth phase respectively. The results indicated a significant differentiations among results and presence of correlation coefficient between the usage concentrations and mortalities, also between concentrations and days that larvae need to convert to pupa. | ||
