Dry Beans — Pests and diseases

Metadata research draftEvidence limits

⚠️ Status: drafted from the literature survey. Values Unknown until source notes/full text.

Insects

• Bean weevil / bruchid (Acanthoscealides obtectus): major stored/pod pest; resistance breeding exists (candidate 10.17660/actahortic.2009.830.20; wild-accession antibiosis 10.1093/jee/82.1.310). Bruchid variety resistance (candidate 10.62773/jcocs.v6i4.351).
• Seedcorn maggot & seed-treatment control (candidate 10.1093/amt/tsad012).
• Aphids / leaf beetles / thrips — documented generally; beans appear in insect scientific datasets.

Diseases (rich)

• Bean Common Mosaic Virus: genetic interaction (10.18174/202002); bean seed-borne transmission (10.1007/978-981-15-4198-8_29).
• Fungal endophytes in germinated seed — 10.1016/j.funbio.2016.01.017; seed-borne fungal pathogens in farm-saved seed (candidate 10.59324/ejeba.2026.3(3).14).
• Anthracnose / root rots / rust — coverage present.

Birds

• Pod ravens / birds at maturity (plot-scale, esp. pole). Coverage weak; flag (as with other dry-grain crops).

Weeds

• Bean competes moderately; weed presence competition matters. Grain/bean-weed intercropping literature exists (10.5897/ajar10.170).

Mexico / small-scale relevance

• Bean weevil (Mexican) is the Mexican smallholder storage bug — a key frijol concern (10.1093/jee/82.1.310).

Structured-data impact

• Pests/diseases documented narratively; pest_risk in storage pending evidence.
