  • And ultimately die. 

How to control:

  • Setting the cropping pattern by planting simultaneously or with crop rotation. Crop rotation is done to break the life cycle hopper by planting crops or land were left for 1-2 months.
  • Biological control using natural enemies of leafhoppers, such as profit – profit Lycosa Pseudoannulata predators, ladybugs Microvelia of Douglas and Cyrtorhinuss lividipenis, beetles Paederuss fuscipes, Ophinea nigrofasciata, and Synarmonia octomaculata.

  • This pest attacks mainly on the conditions of high humidity.

How to control:

  • Control precedence to the planting of resistant varieties. 

6. Dogs ground or mole-cricket (Gryllotalpa hirsuta or African Gryllotalpa)

  • Eating small animals (predators), but the level of crop damage is greater than the benefits as a predator
  • The young nymphs eat humus and plant roots, growing wings female imago half, the males can be scraped away at dusk.

How to control:

  • Larvae are semi-aquatic, using water as a source of oxygen.
  • The larvae make rolls / bag of rice leaves and then dropped into the water. Green larvae, pupae developments to be 14-20 days. Stadia pupa 4-7 days.

How to control:

  • Negating puddle at the nursery so that the larvae can not utilize water as a source of oxygen.
  • Tabanidae fly and ant Solenopsis gemitata are natural enemies.
