摘要: The potato tuber moth being an important tunnel-feeding pest of potato is responsible for significant crop yield losses worldwide. The endophytic Beauveria bassiana is a potential alternative for pest control and enhanced plant growth. In this context, using behavioral observations under laboratory conditions, we showed that larvae and adults strongly preferred to settle on control plants compared to B. bassiana-colonized ones. We observed that B. bassiana presence led to a strong increase in plant aboveground height (20% increase) as well as fresh weight (21.50% increase). Furthermore, the plants colonized by B. bassiana showed upregulated nicotinate and nicotinamide metabolism pathways, whereas various metabolites produced from the arginine and proline metabolism pathway were downregulated. In term of plant phenotype and metabolomics analysis, endophytic B. bassiana not only reduced the risk of insect pests but also enhanced host plant quality. This method could be a potential tool for controlling Phthorimaea operculella.
