Features
  • Named for their distinctive creamy-white color and plump, C-shaped bodies. They are the larval stage of various scarab beetles, including June beetles and May beetles
  • Plump, 6-legged larvae with a brownish head and a darker, soil-filled rear end. Always found curled in a 'C' shape in the soil
  • Feed exclusively underground on the roots and root hairs of various plants. They sever the roots, preventing the plant from absorbing water and nutrients
  • Initial symptoms are yellowing and wilting, especially during the day. Severely affected plants can be easily pulled from the soil because their root system has been destroyed
  • Beetles lay eggs in the soil during early rains. Larvae hatch and feed on roots throughout the growing season. They overwinter deep in the soil
  • Mature larvae can reach 25-30 mm in length. Large enough to be easily seen when tilling soil
  • Most active and damaging during the rainy season when soil is moist. Prefer soils with high organic matter
  • Attack a wide variety of crops including peanuts, sugarcane, maize, sorghum, pulses, and many lawn grasses
  • Deep summer plowing exposes larvae to birds and the hot sun. Avoid heavy application of undecomposed manure which attracts egg-laying beetles
  • Apply beneficial nematodes or Metarhizium anisopliae (fungal biocontrol) to the soil. Hand-collection during plowing is very effective
