Identification of floral volatiles from Fagopyrum esculentum that attract Cotesia vestalis with potentially better biocontrol efficacy against Plutella xylostella.

In summary, the findings provide insights into the chemical ecology of plant-parasitoid complexes and support the potential use of F. esculentum as insectary plants in habitat manipulation against P. xylostella by supplying natural nectar food for the C. vestalis population. Our results suggest a attract and reward strategy based on an attractant for C. vestalis to control P. xylostella, or the development of volatile-based artificial food for C. vestalis.
