Broad Bean Beetle (Bruchus rufimanus)
Seed beetle attacking developing broad beans and reducing seed quality.
Broad bean beetle (Bruchus rufimanus) lays eggs on developing pods; larvae bore into seeds, reducing quality and germination. In field crops this is often managed culturally, but for seed production and specialist growers it is more significant. Biological control includes entomopathogenic fungi and nematodes in soil, plus trapping and sanitation to reduce adult populations.
