“…This is seriously lacking in the triple-layer hermetic bags due to its air tightness hence the inability of the insects to survive, reproduce and cause damage and weight loss [13,25]. Similar results were obtained from studies on cowpea in Niger, Burkina Faso, Benin, Northern Ghana and other West African countries [13,26,27].…”

Studies were carried out under laboratory conditions of 32 ± 2°C and 58-88% r.h. to determine the effectiveness of the triple-layer hermetic bag against the Larger Grain Borer, Prostephanus truncatus (Horn) and the maize weevil, Sitophilus zeamais (Mot) on stored maize. Three storage bags (Triple-layer hermetic bag, Jute and Polypropylene) and three maize varieties (Obatanpa, Abrodenkye and Kamangkpong) widely cultivated in Ghana were used in the study. A factorial experiment was conducted involving 5 kg of each maize variety with moisture content between 12.5-14%. These were stored in the various bags and a destructive sampling of 54 bags (27 bags for each insect species) was done each month for a 6 month storage period. Percentage damage, weight loss and mean development periods of insect numbers were determined. Mean grain damage and weight loss were significantly different (p<0.001) in the different storage bags. The triple-layer hermetic bag recorded the least mean weight loss of 2.94% while jute and polypropylene bags recorded higher mean values of 19.55% and 23.65% respectively. Prostephanus truncatus caused the highest mean weight loss of 17.19% while S. zeamais caused 10.57%. The high yielding improved variety (Obatanpa) was the most susceptible with a mean weight loss of 16.75% whiles Kamangkpong recorded the least susceptibility to both insect species with a mean weight loss of 11.09%. Abrodenkye recorded 13.55% weight loss. Moisture content and insect numbers were significantly different (p<0.001) in the various bags. It is therefore recommended that the triplelayer hermetic bag should be used for quality preservation of maize.

“…These techniques have been developed and well-recognized among the scientific community for a long time (Dales, 1996;Ilesanmi & Gungula, 2010;Kitch, Ntoukam, Shade, Wolfson, & Murdock, 1992;Murdock, Seck, Ntoukam, Kitch, & Shade, 2003;Sanon, Dabiré-Binso, & Ba, 2011;Seck, Longnay, Haubruge, Marlier, & Gaspar, 1996;Wolfson, Shade, Mentzer, & Murdock, 1991). For example, the triple bagging technology of cowpea storage was developed by Purdue scientists through USAID funded Bean/ Cowpea Collaborative Research Support Program (CRSP) in the 1990s and efforts have been invested in recent years to disseminate this technology through special donorfunded projects (e.g.…”

“…Additional benefits of triple bagging include no use of pesticide; the grains are ready to be consumed when the bags are opened; good for storage of small and large quantities of cowpea; and the bags can be stored in homes. The use of triple bagging method has shown to reduce grain loss from seed damage by 65-90% (Baoua, Margam, Amadou, & Murdock, 2012;Sanon et al, 2011), and the solar disinfestation method results in almost 100% mortality of the bruchids (Kitch et al, 1992;Murdock et al, 2003). Despite these advantages, adoption of these storage techniques has been limited because farmers are not aware of the technology, do not understand how to implement the technology or do not have access to plastic material or bags required to use these methods (Ibro et al, 2014;Moussa, Lowenberg-DeBoer, Fulton, & Boys, 2011;Moussa, Tahirou, Coulibaly, Baributsa, & Lowenberg-DeBoer, 2014).…”

This article explores an innovative approach to deliver information about new agricultural technology that combines a versatile and potentially lower cost method of developing animated videos with another low-cost method of sharing it on mobile devices (i.e. mobile phone). It describes a randomized controlled field experiment conducted in Burkina Faso to evaluate the effectiveness of animated videos shown on mobile phone compared with the traditional extension method (live demonstration) in inducing learning and adoption of two postharvest technologies among low-literate farmers. Results suggest that video-based training was as effective as the traditional method in inducing learning and understanding. For technologies that farmers were already aware of animated video shown on the mobile phone was also as effective as live demonstration in inducing adoption. However, in transferring new technologies, the traditional method was more effective in inducing adoption at p < .10, but not at p < .05. Potential role of mobile phone-based videos as part of the agricultural extension system is discussed.

“…The technology was named "Purdue Improved Cowpea Storage" (PICS) bags and served as protection against Callosobruchus maculatus (F.) a destructive cowpea seed (bruchids) beetles (Murdock et al, 2003). PICS are based on the principle of the bio-generated modified atmosphere, where oxygen environment low inhibits the growth and development of insect pests (Sanon et al, 2011). It takes advantage of an airtight seal where oxygen concentration dramatically decreases (Figure 19), While carbon dioxide levels proportionally increase within a few days after sealing through respiration of insect, fungal, and grains/seed (Quezada et al, 2006).…”

Agriculture is the backbone of Tanzanian economy. It accounts for about one-third of the gross domestic product (GDP), provides 85 percent of all exports and saves as a livelihood to over 80 percent of the total population. Maize is the primary staple crop; it's grown in nearly all agro-ecological zones in the country. Tanzania is a major maize producer in Sub-Saharan Africa. In the last four decades, Tanzania has ranked among the top 25 maize producing countries in the world. In the 2013/14 growing seasons Tanzania produced over half billion metric tons of maize of these maize smallholder farmers produced around 85%. Despite the steady production of maize over the past three decades, post-harvest losses of maize remained significant, up to 30-40 % in some rural areas. Post-harvest handling, poor infrastructure, weather variability, biotic factors such as insects and pests, bacteria, pathogens, viruses, and fungi, often aggravate such losses. Mycotoxin producing fungi pose a major risk. Mycotoxins are toxic secondary metabolites of fungi that frequently contaminate the maize in the field and/or during storage. Mycotoxin contamination of maize poses a health risk to humans and animals if not properly managed. The most important mycotoxins in Tanzania are the aflatoxins, fumonisins and Ochratoxin. The objective of this paper was to review current literature on the production trends, consumption, post-harvest losses, and mycotoxins contamination of maize and to provide strategies to control and prevent postharvest losses and mycotoxins contamination in Tanzania.
