Abstract: 

Using Galleria soil trap, two isolates of Beauveria bassiana have been isolated from soil of Fashand and Atashgah regions of Iran. Preliminary assays showed that, these two isolates together with one isolated from pupae of Red Palm Weevil (Rhynchophorus ferrugineus) in Saravan are pathogenic to Locusta migratoria and some other long and short horn grasshoppers.
Bioassays showed that, the lowest LD50 belong to isolate Fashand when using against male insects of L. migratoria numbering 1.32x 103 spore/insect and the highest one scored 3.59x 104 spore/insect in female insects treated with isolate Atashgah. The lowest LT50 recorded at dosage 105 spore/insect of isolate Fashand in male insects.
Using a. local odorless kerosene as the carrier of spores had no adverse effect on spores viability and completion of infection in host. Further this carrier checked the limiting dIect of low humidity on spore germination.
