Bean weevil (bruchid)
Stored seeds show round exit holes, small brown beetles and tiny white eggs glued on the seed coat.
Also called
Bukbok
Crops it attacks
Where the damage shows
On fruits, pods or nuts
When to act
Check stored seed every 2 weeks: small round exit holes or white eggs stuck on the seed mean the weevils are breeding. Act at once, since numbers double fast in warm stores.
Before you spray
Do not spray seed you will eat or sell. Dry the seed well and keep it in sealed, airtight containers so the weevils die.
How to prevent it
- Harvest pods as soon as they dry. Weevils lay eggs on pods left long in the field.
- Sun dry the seed well before storing, until it cracks when bitten.
- Store in airtight containers such as sealed drums, thick plastic bags inside sacks, or bottles filled to the top. The weevils die without air.
- Mix stored seed you will eat with a thin coat of cooking oil, or with fine sand or wood ash, so eggs cannot hatch.
- Clean the store and old sacks before the new harvest goes in, and never mix new seed with old infested seed.
