Abstract
The purpose of this study was to select and identify bacteria as a biocontrol in the
4QPEPQUFSB
sp. worm. The bacterial stains exhibited
JO
WJUSP
testing to kill armyworm were screened.
Total 750 lavae at secoundary stage were tested with Diet plug method. The bacterial isolates SC1 and
SC2 were presented significant
(
Q
<0.05) to
kill infecting larvae compared with sterilized distilled water
as a control. The two isolates were identified with high identity as
#BDJMMVTǰ UIVSJOHJFOTJT
based on
phenotypic criteria and 16s rDNA gene sequence analysis.
