Management of thrips vectoring terrible plant viruses encounters big challenges due to their serious resistances against chemical pesticides. In this work, as an alternative with targetting soil-dwelling larval and pupal stages, Beauveria bassiana ERL836 GR and WP have been developed based on solid culture and formulation technology, and successfully registered and commercialized with guaranteeing four-year of circulation. Farmers’ reputation for ERL836 is very high since 2018 and now it becomes a No. 1 steady seller in this local market. ERL836 formulations could be directly applied to non-tillage soil before transplanting or drenched in the middle of growing. The whole genome of ERL836 was fully sequenced and different from other B. bassiana isolates in genome levels. When infecting thrips, ERL836 strongly up-regulates plasma membrane-mediated transporter activity and fatty acid degradation pathway including cytochrome P450. Finally, a concept of e-biopesticide is suggested for successful commercialization of microbial insecticides.
