“…Smallholder farmers in sub-Saharan Africa have widely used pesticide Source: Author as a strategy to contain insect multiplication. However, pesticides are effective for a limited time, posing the need for regular reapplication for extended grain storage, increasing the cost of pest control, environmental problems, and consumer exposure to health; Previous studies have also reported decreased actellic effectiveness against insects with time ( Denloye et al, 2008;Nhamucho et al, 2012;Mubayiwa et al, 2021). For instance, De Groote et al ( 2013) reported that polypropylene bags treated with actellic effectively controlled insect multiplication in maize and prevented grain damage only for four months.…”

The study evaluated the performance of polypropylene bag (PP), polyethylene drum (PD), polyethylene silo tank (PST), and super grain bag (SGB) on preserving maize quality. The trials were conducted onstation and on-farm. Insect density, grain damage, weight loss, and grain moisture content were determined monthly for six months for on-station trials. For on-farm, insect density and grain damage were assessed every two months for eight months, and the acceptability test of the grain was performed after the storage period. The initial insect density of the grain was 26 insects/kg (natural infestation), and the percentage of damaged grain was 1.6%. After six months, for grain stored in PP, the insect density increased by 31-fold, whereas damaged grain increased by 10-fold, resulting in a 31fold increase in grain weight loss. In contrast, the insect density did not increase significantly in SGB, PD, and PST over six months of storage. Grain stored in SGB presented the highest acceptability, while grain stored in PP was considered unfit for human consumption. The on-farm trials confirmed the effectiveness of the SGB, PD and PST on minimizing insects' multiplication and grain loss, making them suitable for reducing maize losses during long-term storage under smallholder farmers' conditions.

“…22 The methanol extract of the stem of Adenocalymma has shown cytotoxic activity against colon cancer cells. 23 Chirunthorn et al reported antioxidant and antimicrobial activity with petroleum ether and ethanol extracts. The present study was therefore designed to study the efficacy of A. alliaceum (aqueous and methanol) leaves extracts in their ability to control Callosobruchus maculatus in stored cowpea grains.…”

Low permeability triple-layer plastic bags prevent losses of maize caused by insects in rural on-farm stores

Participatory on-farm trials were conducted to assess effectiveness of Purdue Improved Crop Storage (PICS™) bags for storage of maize in small-scale farmers' stores in rural villages in eastern Kenya. A PICS bag is a three-layered hermetic bag-system that forms a barrier against the influx of oxygen and the escape of carbon dioxide. Jute, woven polypropylene or PICS bags were filled with shelled maize grain, purchased from the participating farmers, and the three sets of bags kept in the farmers' own stores for 35 weeks. Oxygen and carbon dioxide levels in the PICS bags were monitored, as well as the temperature and relative humidity in all the bags. Grain moisture, live insect population, grain damage and weight loss were examined at intervals of seven weeks. Oxygen and carbon dioxide composition demonstrated that PICS bags are capable of sustaining good air-barrier properties under farmer storage conditions. Moreover, moisture content of maize stored in PICS bags did not change throughout the storage period whereas the moisture content of maize stored in polypropylene and jute bags decreased significantly in the final 14 weeks. Maize stored in PICS bags remained free from insect infestation and the weight loss due to insect damage was below 1 %. On the contrary, polypropylene and jute bags permitted profuse build-up of insect populations. At 35 weeks, grain damage reached 77.6 % and 82.3 % corresponding to 41.2 % and 48.5 % weight loss in the polypropylene and jute bags respectively. These findings demonstrate that PICS bags are effective in controlling losses caused by storage pests under farmer storage conditions.
