Termites: Odontotermes obesus Rhamb


  • Characteristic semi- circular feeding marks on the margin of the leaves in the standing crop.
  • Poor germination of setts (after planting)
  • Causes yellowing and drying of outer leaves first followed by the inner leaves
  • Entire shoot dries up and can be pulled out.
  • Setts hollow inside and may be filled with soil.

Identification of pest:

  • Eggs: Dull, kidney shaped and hatches in 30-90 days
  • Nymphs: Moult 8-9 times and are full grown in 6-12 months
  • Adult: Creamy coloured tiny insects resembling ants with the dark coloured head.


Cultural method:

  • Flood irrigation at the time of planting because it stops termite attack due to excess moisture and the optimum moisture level will revive.
  • Fill the gaps in the field to compensate the population

Physical method:

  • Locate and destroy the termite colony.
  • Collect and destroy the termite affected setts from the field.

Chemical method:

  • Dip the setts in imidacloprid 70WS 0.1% or chlopyriphos 20 EC 0.04% for 5min.
  • Treat the soil with lindane 1.6 D @ 50 kg/ha.
