Dinoderus minutus

Appearance

Bamboo Borer

  • The Bamboo wood borer has a dark brown body which is plump, almost cylindrical, and is 2 to 3.7 mm in length.
  • The antennae of the Bamboo wood borer broaden at the tip, with the last 3 segments considerably larger and ending in well-defined antenna clubs.
  • The humped thorax of this wood borer conceals the head and has teeth-like indentations in its rounded front. Two large dimples at the back of the thorax.
  • Elytra (wing cases) are covered with small pits and bristly hairs.

Lifecycle

  • The female Bamboo wood borer lays 27–35 eggs into the food substrata. Its larvae hatch and bore into the plant.
  • Larva undergoes up to 4 development phases and pupates inside the plant.
  • The lifecycle of the Bamboo wood borer can be as short as 60 days in good conditions (35 °C, 75% relative humidity) leading to multiple generations per year.

Habits

  • The Larva feeds on bamboo cane, but the weevil is also known to breed on cassava root.
  • Larva makes tubular passages along plant fibers and emerges leaving a perfectly round hole.
  • This species of wood borer is originally from East Asia, and was brought in with cargo on ships (e.g. tapioca products), wooden packaging and even wooden musical instruments.
