Morphological changes of the larvae fed on nanoparticles of the dsRNAs. a Compared with the third-instar larvae of the blank control (1) and those fed on dsgus (2), the dead larva which had fed on DOPAL synthase dsRNA were unable to detach from the exuvia (3). b Compared with the fourth-instar larva of the blank control (1) and those fed on dsgus (2), the larva which had fed on DOPAL synthase dsRNAs showed a much smaller size (3)
