| Abstract | ||
| < p >Using Sunn pest as target insect the LC50 and LT50 of eight different Iranian and imported isolates of Beauveria bassiana have evaluated under laboratory condition. The lowest LC50 and LT50 values were observed in isolate DEBI002 being 3.78×10 3 spores/ml. and 8.55 days respectively showing among tested isolates the latter is the most virulent one. Five different plant oils were used to evaluate the viability of the spores of selected isolate during storage. Among the oils tested the palm oil showed to be the most and Sesame oil the least suitable carriers for B. bassiana aerial conidia. | ||
