The effect of breaking up the artificial diet of Euscepes postfasciatus into small pieces before egg seeding on the diet was examined as a possible method for improving larval survival rate in the mass rearing of the species. Breaking up the diet realized a 10-fold increase in number of emerging adults compared to the use of a non-broken up diet. Although the air permeability of the rearing tray was previously shown to affect survival of the species in a rearing method with a non-broken up diet, it did not significantly affect the survival rate when a broken up diet was used in the present study; therefore, a broken up diet is considered to be effective for ensuring good survival of the species, particularly in terms of a stable survival rate irrespective of the air permeability of the rearing tray.
