Plant growth-promoting rhizobacteria (PGPR) can help plants to deal with biotic and abiotic stresses via plant growth promotion and induced resistance. Such beneficial belowground microbes interact in bidirectional way via the plant with above ground insects such as herbivores and their natural enemies, and pollinators.  Currently, little is known on the effect of PGPR treatment on insect-plant interactions. Here we show the effects of different PGPR strains on the ovipostion behavior and larval development of Spodoptera exigua on treated cotton plants.

Key words: PGPR, Ovipostion behavior, larval performances, trichome density, lignin and wax content
