AbstractIn this laboratory study,the effect of different concentrations of local isolate of entomopathogenic fungus Beauveria bassianaagainst potato tuber moth Phthorimaea operculllellawas evaluated. In addition, GC Mass technique was used to identify the chemical compounds in the crude filtrate, the most important of which are Phenol, Methane, Ethane of B. bassiana. The results showed that B. bassianawas significantly the highest efficacy against compared to fourth instar larvae of P.operculllella.Where the mortality rate was 41.67 and 32.96% when at a concentration of 7.5 g/L, respectively. The overall results indicated that the fungus has a high efficiency in affecting the eggs and larvae of the fourth instar of the insect, which can be used efficiently to reduce the infection rate in the insect and can be a promising method for insect control and plant protection.
