PESTS OF PULSES :: Major Pests :: Termites


9. Termites: Odontotermes obesus (Termitidae: Isoptera)

 

Host plants – wheat, barley, sugarcane, pea, sorghum, pearl millet, maize, groundnut.

Damage symptoms: Termite damage starts soon after sowing and continues till the growing stage.  The leaves of damaged plants droop down which later wither and dry. Such plants are easily uprooted. 


Bionomics:
7-10 days after aerial flight the female lays the first batch of eggs numbering 100-130.   These eggs hatch in 40-42 days.  The female termite then swells to become queen and lays upto 30,000 eggs per day.  The members of this group are social insects and are composed of workers, soldiers, king and queen.
