Preventive Control

Natural enemies

Native parasitic wasps and flies (CABI, 2000)


  1. Praying mantis
  2. Spider

Cultural and management practices

  1. Intercropping legumes with corn lessens the attack of bean fly.
  2. Mulching plants with rice straw and with cut weeds.
  3. Hilling-up or ridging of young plants 4-5 weeks after planting (CABI, 2000).
  4. Crop rotation with non leguminous crops.
  5. Avoid late planting if infestation is prevalent in the area. Plant at the same time as with the other farmers in the area.
  6. Plow-under all plant residues from the field after harvest.
