Flea beetles (Chaetocnema spp.)
Flea beetles make small holes in the leaf when feeding, however, this damage is considered minor. Most important, these beetles are potential vectors of the Rice Yellow Mottle Virus. Flea beetles are small, and have enlarged hind legs and jump when disturbed.
- Use proper spacing. Populations of flea beetles are affected by the spacing of transplanted seedlings. Studies in West Africa have shown that population of this hispid beetle was higher in close spacing of 10 x 10 cm) than in wider spacing of 20 x 20cm (WARDA).
- Keep bunds and surroundings free of grass weeds.
- Destroy stubbles and avoid ratooning.
- Ensure balanced nutrition. Avoid excessive nitrogen application.
