摘要: Abstract Rose sawfly Arge rosae (Hym; Argidae) is the most serious pest of flowers Rosaceae family. In order to evaluate potential entomopathogenic fungi for controlling this pest, fourth instar larvae were maintained under controlled conditions and exposed fungi, Beauveria bassiana . The bioassay was carried out by immersion method with concentrations 2 × 10 4 , 5 6 7 8 conidia/ml Tween-80 solution (0.03%) in distilled water. Each concentration replicated four times ten insects each replicate. results showed relatively high efficacy these isolates on insect pest. case IRAN 403C isolate, values LC 50 LT obtained as 5.54 × 10 3.92 days at conidia/ml, respectively. Results that isolate caused highest mortality comparison other a mean 70% using 10 conidia/ml.
