Abstract
The emerging elicitor protein PeBL1, extracted from Brevibacillus laterosporus A60, was tested against the potato aphid (Macrosiphum euphorbiae) for its biocontrol potential. Its effects on M. euphorbiae survival, lifespan, immature development, adult reproductive performance, and pest–pathogen interaction were assessed using electrical penetration graphs (EPGs), The levels of jasmonic acid (JA), salicylic acid (SA), and ethylene (ET) were significantly increased in the B. laterosporus-treated C. annuum seedlings, indicating substantial accumulation. Brevibacillus laterosporus improved the height of the C. annuum L. plant and the surface structure of the leaves, by reducing M. euphorbiae reproduction and preventing colonization, according to the findings of this study. The activation of pathways was also part of the defensive response (JA, SA, and ET). The use of B. laterosporus for integrated pest management in the agroecosystem appears to be suitable based on these findings against M. euphorbiae.
