Japanese pine sawyer beetle (JPSB), Monochamus alternatus is a forest insect pest with damaging to pine trees through vectoring plant-parasitic nematodes. In our previous work, the entomopathogenic Metarhizium anisopliae JEF-197 was effective in controlling JPSB adults. However some of JPSB adults survived well even against the fungal treatment. Now here in this work, we analyzed the transcriptome of JEF-197 from the fungus-treated JPSB adults which still survived in 8 days after the treatment. The day was determined based on the lethal time 50 (LT
