Implication

Laboratory experiments show PGPR significantly reduce growth and feeding efficiency of Spodoptera litura, suggesting alternative pest control methods.

Key Points

PGPR treatments significantly reduced larval consumption and weight gain compared to untreated controls.
Shorter feeding periods and lower consumption indices were observed in larvae fed on PGPR-treated leaves.
PGPR induced systemic resistance, enhancing the plant's defense mechanisms against Spodoptera litura.
Findings support the integration of PGPR in sustainable pest management strategies, with economic benefits.
