Dinoderus is a genus of bamboo powderpost beetles in the family Bostrichidae.

[1][2][3][4] In adults of Dinoderus, the pronotum is hood-like and conceals the head from above (a feature shared with other Dinoderinae).

[5] Some species in this genus, namely D. japonicus, D. minutus, D. ocellaris and D. brevis are major pests of bamboo, attacking both harvested culms and finished products.

Adults enter culms via wounds or cut ends, make horizontal tunnels and deposit eggs.

These hatch into larvae, which bore longitudinally in culms, making criss-crossing tunnels.
