Rice Hispa control measures (Management), Pest characters, and Nature of Damage

Scientific name: Dicladispa armigera.   

Family: Cecidomyiidae.    

Order: Coleoptera.  

Pest characters of Rice Hispa   

1.      Medium-sized insect.   

2.      Elytra with a spine, blackish color.   

3.      Mouthparts → Chewing type.   

4.      Both grub and adult are harmful.   

Nature of Damage of Rice Hispa 

1.  The female insects lay eggs in single at the ventral side of the leaf tip.   

2.  After 5­8 days the eggs are hatched and the grub cames out.   

3.  The grub mines the leaf and feed on tissues in between two epidermal layers and make tunnel. The infected leaf become whitish, membranous and finally die. The adult, scrap the chlorophyllous tissues of the leaf and make white streak along the vein. In severe condition, the infested leaf becomes papery white and photosynthesis and yield reduction occur severely.    

Rice Hispa Control Measures/Management

A) Non­chemical control of Rice Hispa   

1.      Collection and destruction of adult by using hand net.   

2.      Using resistant variety. e.g. BR 14, 28, 29 etc.   

3.      Destruction of the alternate hosts.   

4.      Both adult and grub infestation can be reduced by leaf clipping, 6-­8 cm below from the tip.   

5.      Destruction of crop residues.  

6.      Rope soaked with kerosene water drag across the rice field.   

B) Chemical control of Rice Hispa            

i.            Using Basudin 10G/ Furadan 3G @ 16 kg/ha.         

ii.            Spraying with Cypermethrin 10 EC or Phosphamidon 100 EC @ 1.5 ml/L of water.       

iii.            Application of Dursban 20 EC @ 1 L/ha.        

iv.            Application of Marshal 20 EC @ 1.2 L/ha.          

v.            Application of Diazinon 60 EC @ 1 L/ha.        

vi.            Application of Sumithion 50 EC @ 404 ml/acre of land.
