Hello Morkaz

Various systems to produce recombinant proteins are available. Bacteria, especially Escherichia coli, are usually chosen first, due to the abundance of tools available for gene manipulations and the simple process for protein production. You can read this paper is attached

To produce recombinant baculovirus directly in insect larvae? It is very difficult to screen the recombinant viruses in larvae.

No not really. Why do you want to do this rather than in one of the more common approaches (cells, bacteria)? There may be a workaround.

Thank you for everyone to answer me
