Abstract	Three isolates of Metarhiziumanisopliae var. acridum, FI-985,from the spur-throated locust, Austracrisguttulosa from Australia, and QF-01 and QF-02both from Schistocerca piceifrons inMexico were compared. FI-985 had much largerconidia than the other two isolates and alsohad a different colony appearance. The twoMexican isolates showed small differences inconidial size and colony morphology. Over arange of 6 primers, RAPDs patterns were verysimilar in that the two Mexican isolates being identical, and FI-985 having some unique bandsonly with 2 primers. The 3 isolates were alsosimilar in growth profiles on agar plates, andat high temperatures (36°C), QF-01 didnot grow while the other two isolates grewslowly. All three isolates were similar invirulence for wingless grasshoppers, Phaulacridium vittatum, at 20–30°C but at 35°C, FI-985 was the mostvirulent and QF-01 the least over a range of 3doses. At 15°C, FI-985 was also the mostvirulent with QF-02 being least virulent. At30°C, the LD50 at 17 days rangedfrom 248 conidia for QF-02 to 501 conidia forFI-985, however the differences were notsignificant (p > 0.05). It is suggested thatconsideration should be given to using anexotic isolate such as FI-985 as a commerciallocust biopesticide in countries such asMexico, since the isolate is cheap to massproduce, more effective at higher temperaturescommon in tropical to subtropical Mexico, andrelatively resistant to UV.
