The continuous emergence of chemical-mediated residual toxicity and insect resistance have enforced the regulation of synthetic pesticides. Synthetic pesticides with novel mode of actions could be developed to overcome these issues, but as an alternative biopesticides with more efficacious control activity could be developed by the advanced technology. In pest management, entomopathogenic fungi have high potential in reducing pest population to an economic threshold, and some of isolates have been commercialized. However still a novel application strategy needs to be considered for successful industrialization. An insight on fungal genes in whole genome and transcriptome levels is necessary to understand the role of genes in pathogenesis and genetic diversity of fungal genes. Herein, we have identified the genetic differences of entomopathogenic fungi using whole genome sequencing of Beauveria bassiana (Bb) and tried to understand the interaction between fungus and insect using RNA-seq. We have obtained the whole genome sequence of Bb JEF-007 using PacBio sequencing technology and compared the transcriptomes of Bb JEF-007 and bean bug, Riptortus pedestris before and after the fungal infection using Hiseq 2000 system.
