Abstract :In this study, efficacy of different spore concentrations of Fusarium subglutinans 12A isolate on Tetranychus urticae Koch females was investigated. The experimental design was a complete randomized block and all trials were conducted in five replications. In the study, 1x10 4 , 1x10 6 and 1x10 8 spore/ml spore concentrations were applied to shell bean leaves that prepared according to leaf disc method spraying in droplets at 1 atm pressure. Observations on mortality of females and also mycosis developing on dead individuals were conducted 3 rd , 5 th , and 7 th after application. According to the study results, mortality rates were different than control in three spore concentrations, but they did not differ from each other insert ignore into journalissuearticles values(P> 0.05);. Mycosis were not significant in three spore concentrations insert ignore into journalissuearticles values(P> 0.05);. Moreover, it was determined that the time-dependent mortality rate after application of Fusarium subglutinans 12A isolate were highest at 7 th days in each spore concentration.
