Insects found in the samples
Maize: • Tribolium spp• Sitophilus spp
Voandzou (Vigna subterranea) • Tribolium spp • Bruchid
Sorghum:
• Tribolium spp; • Sitophilus spp • Oryzaephilus surinamensis, • Cryptolestes spp, • Sitotroga cerealella Oliver• others non identified
Paddy rice:
• Tribolium spp• others
Hibiscus grains: (Hibiscus sabdariffa)
Acanthoscelidae
Groundnut: • Tribolium spp• Corcyra cephalonica
1. Does PICS bagging stop the insect problem?
2. Is grain moisture and molds a problem?
3. Will PICS stored seeds germinate ?
4. Are processing, cooking time, etc. affected?
5. Would PICS intervention be economical?
With each new crop or product:
