Maize stored pests control by PICS-bags: technological and economic evaluation
A trial was conducted in Benin, West Africa to investigate the effectiveness of PICS bags in controlling postharvest pests during maize storage. Sorted and un-sorted maize (25 kg) was stored in either PICS bags (PsB) or polypropylene bags (PPB) as controls with half of the bags being artificially in...

| description | A trial was conducted in Benin, West Africa to investigate the effectiveness of PICS bags in controlling postharvest pests during maize storage. Sorted and un-sorted maize (25 kg) was stored in either PICS bags (PsB) or polypropylene bags (PPB) as controls with half of the bags being artificially infested with 25 Prostephanus truncatus (Pt), and the other half left under natural infestation. Bags were monitored at 0, 3, and 6 months of storage by destructive sampling. Average density of P. truncatus/Kg in PsB (0.30 ± 0.11) was significantly different from levels observed in PPB (0.96 ± 0.12) after 6 months of storage. One hundred percent mortality of P. truncatus was obtained after 3 months of storage in PsB. Similarly, there were statistical differences in the average density of Sitophilus zeamais/Kg between PsB (1.35 ± 0.41) and PPB (238.75 ± 2.38) and 100% of mortality of S. zeamais was detected in PsB, whereas PPB showed only 34.05 ± 2.69% of mortality after 6 months of storage. Weight losses were lower in PsB (0.31 ± 0.01) than the control (17.95± 0.51)). After 6 months, at most 0.75 ± 0.47 holes were observed on the inner bag of PsB, whereas 350.75 ± 25.38 holes were observed in the control. In general, PsB showed effective control against the two main postharvest species P. truncatus and S. zeamais after 6 months of storage, despite the slight increase in moisture content of stored maize in all bags. The effectiveness of storing maize with PICS bags was apparent within the six-month storage period. |
