Girdle beetle

Girdle beetle: Oberea (Obereopsis) brevis

Symptoms of damage

  • Girdling of  stems and petioles
  • The inside of the stem is eaten by the larvae and a tunnel is formed inside the stem.
  • The leaves of a plant of the infected portion are unable to get the nutrient and are dried up.
  • In later stages, the plant is cut at about 15 to 25 cm above the ground.

Identification of the pest

  • Larva: White, soft-bodied worm with a dark head.
  • Adult: The freshly emerged adult is yellow, red, brown on the head, thorax and bases of elytra.


  • Deep summer ploughing
  • Planting time on the onset of monsoon
  • Optimum seed rate (70-100 kg/ha) should be used
  • Intercropping with maize or sorghum should be avoided
  • Crop rotation should be followed
  • Avoid excess nitrogenous fertilizers.
  • Collect and destroy infested plant parts and egg masses.
  • Remove the infested plant parts at least once in 10 days and bury them in compost pit to monitor and reduce the populations of girdle beetle
  • Apply phorate 10 G @ 10 kg/ha or carbofuran 3 G @ 30 kg/ha at the time of sowing.
  • One or two sprays of 0.03% dimethoate 30 EC or 0.05% quinalphos 25 EC or 0.05% methyl demeton 25 EC or 0.04% can check further damage.
  • Spray quinalphos 25 EC triazophos 40 EC @ 2 ml/lit. at the crop age of 30-35 days and repeat after 15-20 days (1000 l spray/ha).
