Fig 4. Analysis of D. suzukii physiological interaction with L. heterotoma and L. boulardi parasitoids.
D. suzukii L1 and L2 larvae parasitized by the French strain of L. heterotoma (LhGoth) or the field strain of L. boulardi (Lb16) were dissected 48h (L1 and L2) or 72h (L1) post-parasitism to evaluate the state of the immune response, as described in Fig 3. Pie charts give the percentage of alive or dead fly larvae containing free parasitoid larvae, free floating eggs, wasp eggs or parasitoid larvae only surrounded by a thin coat of lightly-colored cells, wasp eggs or larvae partially melanized (coat of lightly-colored cells with a few black spots), completely encapsulated parasitoid larvae (fully melanized) and completely encapsulated eggs.
