“…Tanzubil (1991) found that C. maculatus could damage 100% of stored seed causing weight loss of up to 60%. After six months of storage, losses in terms of perforated seeds can reach 90% (ICRISAT, 1992;Seck et al 1996).…”

Ten varieties of cowpea grains were infested with Callosobruchus maculatus. This was to determine the level of quality deterioration of the cowpea varieties caused to the grains by the insects. The insect census taken at one, two and three months showed a progressive increase in insect population from one month to three months. The quality deterioration was determined by proximate analysis of the grains at one, two and three months. The percentage total protein determined by the estimation of total nitrogen content, showed an increase from one month to three months. The total protein in the control experiment showed a progressive decrease with increase in storage period. The percentage ash in the control was higher than the infested, and it decreased with storage period. The percentage fat decreased with infestation. The control had a higher percentage fat than the infested, but the fat decreased with storage period. The percentage fibre was higher in the infested grains than the control, and it increased with infestation period. The percentage carbohydrate decreased with infestation. The control samples had higher carbohydrate than the infested ones. The percentage carbohydrate however, decreased with increase in storage period. There was a significant difference (p 4 0.05) in the insect population amongst the different cowpea varieties.

“…In effect, cowpea production has gone a long way to cut down the problem of hunger in most parts of Africa. However, post-harvest losses usually caused by cowpea bruchids remain a key problem for many farmers [1,3,4]. The attack caused by cowpea weevil (Callosobruchus maculatus) has destroyed between 20 and 50% cowpeas on the continent each year, and in certain areas this loss could be up to 100% [5].…”

Background: Cowpea (Vigna unguiculata) serves as a major food and income generation crop for millions of people in sub-Saharan Africa and Central America. However, post-harvest losses associated with this crop still remain a critical issue of concern in most developing countries. This study was therefore carried out to investigate the effect of hermetic and non-hermetic storage on cowpea in plastic containers in the tropics. The cowpeas were stored in hermetic and non-hermetic containers over a period of 12 weeks. The parameters evaluated were the moisture content, insect infestation, usable proportion, and 1000 grain mass in both hermetic and non-hermetic systems. Results:The moisture content in the hermetic containers increased slightly from 11.7 to 11.9% compared to a sharp increase from 11.7 to 17.2% in the non-hermetic plastic containers. From the fourth week to the twelfth week, the number of live insects drastically reduced to zero in the hermetic system. In the case of the non-hermetic containers, the population of live insects/100 g of grains increased from 5 on week 0-71 on the twelfth week. Also, the mass of 1000 grains reduced from 156.50 g on week 0-145.21 g in the non-hermetically stored grains, while the hermetically stored grains recorded a decrease to 148.95 g. Finally, the usable proportion of grains in the hermetic system declined from 98.55 to 94.80% after 12 weeks of storage as compared to the drop to 85.69% seen in the non-hermetic system. Conclusions:Based on our findings, it was further concluded that hermetic storage could offer a better way of storing cowpea as compared to the non-hermetic system.

“…The action of the BPBs and WPBs could be compared to what happens when grains are stored in the Purdue Improved Cowpea Storage (PICS) bags [32]. Sealed PICS bags work, as do other hermetic storage containers, by excluding oxygen and raising the temperature of stored grains [54,55].…”

Neem (Azadirachta indica A. Juss.) seed oil (NSO) is acclaimed to have some form of insecticidal action against more than 400 insect species in at least 10 to 13 orders. The main delimitating factor in the wide acceptance of this well tested plant as a storage pest bioinsecticide is its foul sulfurous smell and bitter taste which impinges on the acceptability and marketability of treated produce. To ameliorate this shortfall, therefore, an assessment of the potential of impregnating different storage materials; [plastic containers (PLC), Bagco bags (BCB), Black polyethylene bags (BPB), white polyethylene bags (WPB) and calico bags (CAB)], with NSO in the management of Callosobruchus maculatus (F.) in stored Bambara seeds (Vigna subterranea L.), was conducted in the laboratory. The experiment was laid out in a 4 x 5 factorial arrangement fitted into a completely randomized design (CRD). Factor A represented four concentrations of NSO (0.00, 0.50, 1.00, 1.50 ml/ 100g seed), while factor B were the five different storage materials. The treatments were replicated four times Generally, seeds stored with impregnated storage materials recorded more bruchids mortality, reduced oviposition rate, decreased number of emerged insects (F 1 and F 2 ) and had less damaged seeds (and hence decreased weevil perforation index, WPI) than the control. Concentration performance was dose related though the highest (1.50 %) did not differ statistically (P=0.05) from the medium (1.00 %) concentration. Seeds stored in BPBs had the highest mortalities, but recorded the lowest in number of eggs oviposited, egg/seed ratio, F 1 , F 2 and cumulative emergence, respectively. These results differed significantly (P=0.05) with the seeds stored in other materials. BPB stored seeds were also the least damaged with lowest exit holes/seed, seeds with holes and WPI, respectively. The performance of BPB was closely followed by seeds stored in WPBs in all the parameters tested. Conversely, seeds stored in BCBs recorded the lowest mortalities but the highest in all other parameters assessed. Other storage materials (PLC and CAB) had better storage quality than BCB materials. Impregnation of storage materials with NSO could be a better option to direct seed application with its attendant drawback. The use of NSO impregnated black polyethylene bags, within the scope of the storage materials screened, to control damage by C. maculatus in stored Bambara seeds, should be encouraged.
