Abstract
In this research, compatibility of Beauveria bassiana and Lecanicillium muscarium with different concentrations of imidacloprid was investigated. Imidacloprid was employed in three different concentrations, mean concentration (MC), half MC and twice the MC and conidial germination and vegetative growth of both fungi were monitored. The study was conducted in Completely Randomized Design with 6 replications. The results showed that imidacloprid is not compatible with L. muscarium and it caused complete inhibition in fungal vegetative growth in 2MC while the average daily growth rate of B. bassiana was not significantly different from the control using this consentration. Likewise, germination of conidia at 2MC treatment was not affected with imidacloprid while in L. muscarium, rate of germinated conidia were reduced significantly compared with the control. Regarding lack of negative influence of imidacloprid on B. bassiana, combination of these two factors can be recommended in integrated pest management programs
