摘要：Biocontrol agents can be derived from endophytes or healthy plant tissues. The
entomopathogenic bacterial group derived from corn plant tissue has the potential as a
biopesticide. The study aimed to obtaine entomopathogenic bacterial isolates, which can
kill test insects and be safe for other living organisms. Roots of healthy corn plants
collected as a source of isolates. Bacterial isolates were tested for gram test, virulence on
Mirabilis jalapa flower plants, and entomopathogenic test for Spodoptera litura. The
results of the study found 29 isolates, which were entomopathogenic with mortality of
35.71 - 100%. Only two isolates showed adverse reactions based on the results of the
hypersensitive and hemolysis test namely isolates P1.7 and P2.1. This indicates that there
were two isolates from corn root tissue, which were entomopathogenic and safe for
living organisms.
