PESTS OF SUNFLOWER :: Major Pests :: Leaf Hopper

1.  Leaf hopper - Amrasca biguttula biguttula (Cicadellidae: Hemiptera)

Damage symptoms: Both nymphs and adults suck the sap from the under surface of leaves.  Leaves become crinkled and cup shaped, growth gets stunted, brownish red colour develops on the edges of leaves and the condition is known as “hopper burn”.  They also attack brinjal, bhendi, cotton and potato.


Bionomics: Adult is a small, slender green insect.  Eggs are laid singly in the leaf veins.  Egg period is 4-11 days.  Nymphs green, wedge shaped.  Nymphal period is 7 days.  Breeding is noted throughout

 the year.



  • Early sowing and close spacing of cotton reduces pest infestation particularly if the rainfall is heavy
  • Setup light trap to monitor the broods of leaf hopper and to attract and kill 
  • Spray monocrotophos 36 WSC @ 1000 ml/ha and NSKE 5% @ 25 kg/ha or 750 ml endosulfan 35 EC in 1000 L of water per hectare.
  • Release predators viz., Chrysopa carnea
