1. Cereals & Food Grains – Highly Susceptible

These are most frequently infested because of high starch content and easy grain penetration.

• Rice (Rice Weevil, Lesser Grain Borer, Angoumois Grain Moth.)
• Wheat (Khapra Beetle, Granary Weevil, Saw-Toothed Grain Beetle.)
• Maize (Corn). (Maize Weevil, Large Grain Borer, Angoumois Grain Moth)
• Sorghum (Jowar)(Rice Moth, Grain Weevil.)
• Pearl Millet (Bajra)(Rust-red Flour Beetle, Saw Toothed Beetle)

2. Pulses – Moderately to Highly Susceptible

Pulses attract bruchids (pulse beetles), which cause serious damage.

• Green Gram (Moong)(Pulse Beetle)
• Black Gram (Urad). (Bruchids).
• Bengal Gram (Chana). (Pulse Beetle, Khapra Beetle)
• Pigeon Pea (Toor Dal)(Callosobruchus chinensis).
• Cowpea (Karamani)- (Pulse Beetle)
• Lentils (Masoor) ( Storage Beetles)

3. Oilseeds – Some Are Very Prone

Oil-rich seeds attract insects + fungus when moisture rises.

• Groundnut (Groundnut Burchid, Red Flour Beetles)
• Sesame (Til). ( Red Flour Beetles, Moths)

4. Spices – Moderate to High Risk Depending on Form

Whole spices store better than powdered spices.

Whole Spices Susceptible

• Chillies (mould + beetles)
• Coriander seeds (spice beetle)
• Cumin (cumin seed beetle)
• Fennel (Saunf) (flour beetles)
• Cardamom (mould, beetles)
• Dry Turmeric (mould + beetles)
• Fenugreek (Methi) (storage beetles)

Powdered Spices – Very High Risk

• Turmeric /Chilli/Masala/Coriander Powders.( Cigarette Beetles, Drugstore Beetles,Flour Beetles)

5. Processed Grain Products – Extremely High Risk

Any broken grain or flour gets infested fastest.

• Wheat Flour (Atta)( Red Flour Beetle, Confused Flour Beetle)
• Rice Flour. ( Beetles & Moths)
• Semolina (Rava). (Flour Beetles)
• Poha / Aval. (Rice Moths, Beetles).
