Abstract:
The aim of this study was to evaluate the effects of different concentrations of the endophytic isolate EN4 of the plant growth-promoting bacteria (PGPB) Kluyvera ascorbata in the development of Plutella xylostella, and the influence of the bacteria on the biological characteristics of the pest in different stages of vegetative growth of cabbage. Different concentrations of PGPB were sprayed on kale leaves before they were fed to caterpillars in the laboratory. After consumption, we evaluated the biological characteristics of the insects. Overall, the results demonstrated that the EN4 isolate had a negative effect on P. xylostella because the viability (larval and pupal) was dramatically reduced in treatments containing the bacteria, which led to a significant reduction in the insect population and less damage to the plants.
