Abstract/Contents:"Blastospores of two isolates of Paecilomyces fumosoroseus were compared to determine their productivity in vitro and their relative pathogenicity after injection of fall armyworm, Spodopters frugiperda. Blastospores of less virulent P. fumosoroseus isolate 1576 are smaller than those of isolate 4461, and they germinate and proliferate more slowly in vitro. The pathogenicity of injected blastospores of isolate 1576 against S. frugiperda varies with larval size. In small larvae, percentage mortality was lower among those injected with isolate 1576 than among those injected with isolate 4461. Large larvae were equally susceptible to both isolates. Survivial times were higher for isolate 1576 and were higher at lower doses for both isolates. Those larvae injected late in development that ultimatley died, regardless of treatment, did not lose weight typical of developing pupae. Injection of large larvae with isolate 4461 resulted in a significantly longer time to pupation among apparently uninfected larvae."
