Abstract :Invasive brown marmorated stinkbug insert ignore into journalissuearticles values(BMSB);, [Halyomorpha halys insert ignore into journalissuearticles values(Hemiptera: Pentatomidae);] are caused significant yield and quality losses in hazelnut orchards. This study evaluated the efficacy of 7 native Beauveria bassiana and B. pseudobassiana isolates against BMSB adults at 1×108 conidia mL-1 concentration under laboratory conditions. The LT50 and LT90 values for all isolates used in the study ranged between 5.37-7.74 and 9.85-18.35 days, respectively. Moreover, the mortality rates caused by all isolates were between 72 and 96%. The lowest LT50 value insert ignore into journalissuearticles values(5.37 days); was recorded for TR-SM-11, whereas the lowest LT90 insert ignore into journalissuearticles values(9.85 days); value was noted for TR-D-1 isolate. Similarly, the LT90 and LT50 values were 10.82 and 7.74 days for TR-SM-11 and TR-D-1, respectively. The LT90 and LT50 values for TR-SK-1 isolate were 6.16 and 10.25 days, respectively. These isolates insert ignore into journalissuearticles values(TR-D-1, TR-SK-1, TR-SM-11); caused the highest mortality rates insert ignore into journalissuearticles values(96, 96 and 92%, respectively); at the end of the 11th day. TR-SM-11, TR-D-1 and TR-SK-1 isolates of B. bassiana seemed to be one of the most promising and potential biological control agents against BMSB. However, further studies are needed to evaluate the efficacy of these isolates against BMSB under field conditions.
