“…Callosobruchus rhodesianus is a destructive stored-product pest, as massive populations can build up in a short time which then exerts a lot of pressure on the stored grain causing high damage and losses in both quality and quantity (Silva et al, 2018), as occurred in the current study in both districts. The levels of insect counts and damage were higher in Mbire than Guruve, which could be attributed to higher ambient temperatures experienced in the former, which promotes more rapid proliferation of the insects.…”

“…A range of different hermetic storage bag brands are being marketed across SSA countries, including Purdue Improved Crop Storage (PICS) bags, GrainPro Super Grain bags (SGBs) IVR™, ZeroFly ® hermetic storage bags and AgroZ ® bags. Hermetic storage containers rely on the principle of oxygen depletion with a corresponding rise in carbon dioxide which occurs as a result of insects, mites, microorganisms on the grain respiring in airtight bags (Murdock et al, 2012;Murdock and Baoua, 2014;Silva et al, 2018). Low oxygen (hypoxia) leads to cessation of C. maculatus larval feeding activity, inactivity, stopping of population growth, desiccation and eventual death of eggs, larvae, and pupae (Murdock et al, 2012;Baoua et al, 2012;Baoua et al, 2013;Murdock and Baoua, 2014;Silva et al, 2018).…”

Cowpea (Vigna unguiculata L. Walp) grain is an important source of protein for smallholder farmers in developing countries. However, cowpea grains are highly susceptible to bruchid attack, resulting in high quantitative and qualitative postharvest losses (PHLs). We evaluated the performance of five different hermetic bag brands for cowpea grain storage in two contrasting agro-ecological zones of Zimbabwe (Guruve and Mbire districts) for an 8-month storage period during the 2017/18 and 2018/19 storage seasons. The hermetic bag treatments evaluated included: GrainPro Super Grain bags (SGB) IVR™; PICS bags; AgroZ ® Ordinary bags; AgroZ ® Plus bags;ZeroFly ® hermetic bags. These were compared to untreated grain in a polypropylene bag (negative control) and Actellic Gold Dust ® (positive chemical control). All treatments were housed in Authors Accepted Manuscript -06/06/2020 2 farmers' stores and were subjected to natural insect infestation. Hermetic bag treatments were significantly superior (p< 0.001) to non-hermetic storage in limiting grain damage, weight loss and insect population development during storage. However, rodent control is recommended, as rodent attack rendered some hermetic bags less effective. Actellic Gold Dust ® was as effective as the hermetic bags. Callosobruchus rhodesianus (Pic.) populations increased within eight weeks of storage commencement, causing high damage and losses in both quality and quantity, with highest losses recorded in the untreated control. Cowpea grain stored in Mbire district sustained significantly higher insect population and damage than Guruve district which is ascribed to differences in environmental conditions. The parasitic wasp, Dinarmus basalis (Rondani) was suppressed by Actellic Gold Dust ® and all hermetic treatments. All the hermetic bag brands tested are recommended for smallholder farmer use in reducing PHLs while enhancing environmental and worker safety, and food and nutrition security.

“…To alleviate the problems of storage in silo and raffia bags and to know the proper time to keep the product stored under the established conditions, it is necessary to use a real‐time monitoring system that can indicate the condition of the stored grain mass, helping the producer anticipate and avoid losses from storage (Aliev et al, 2018; Coradi, Maldaner, et al, 2020; Manickavasagan et al, 2006; Pearson, 2009). Grain degradation during storage can be indicated by changes in the quality parameters, including increased levels of acidity and peroxides, grain browning, and reduced oil, fat, crude protein contents, and starch (Coradi, Müller, et al, 2020; Lakshmanan et al, 2020; Park et al, 2012; Silva et al, 2018; Villers et al, 2006). Therefore, we understand that the monitoring of the corn grain mass is essential, even in an environment considered hermetic (silo bag), to determine the time that the grains can remain stored with quality in that specific storage condition, to make a decision about what to do with the product.…”

The use of silo and raffia bags for the temporary grain storage has been increasing in recent years. However, the methods for monitoring a stored product are limited to visual inspections and sampling. Thus, this research aimed to real-time equilibrium moisture content monitoring to predict grain quality of corn stored in different conditions in silo and raffia bags using wireless sensor network prototype, Internet of Things (IoT) platform, and neural network algorithms. Experiments were conducted using corn grain with two initial water contents of 13% and 18% (w.b.), three storage environments with temperatures of 30, 23, and 17 C, and two types of packaging, that is, silo and raffia bags, for a 3-month storage evaluation. During the monitoring

“…In the untreated grain, the water content reached 21% due to the greater presence and biological activity of the insects. A high water content favors the development of fungi in the grain, impairing its storage quality (ALENCAR et al, 2009) and further increasing the water content, which is related to the biological activity of insects, fungi and mites, in addition to being infl uenced by incorrect storage (FREITAS;SOUSA, 2016;MUTUNGI et al, 2015;SILVA et al, 2018). The germination percentage also varied signifi cantly between treatments (F = 50.68; g.l.…”

The cowpea is subject to both quantitative and qualitative loss during storage due to attack by the insect pest Callosobruchus maculatus (Fabricius) (Coleoptera: Chrysomelidae). There is a growing interest in controlling the pest using insecticides that result from the reactions of secondary metabolites produced by plants, due to their high effi ciency, wide availability and selectivity for the target organisms. The present study aimed to evaluate the fumigant activity of allyl isothiocyanate (AITC) on the development of C. maculatus and its effect on the physical properties of the cowpea. To evaluate the instantaneous population growth rate (r i ), the insects were exposed to concentrations of 3.81, 5.71, 7.67, 9.41 and 17.85 mL AITC m -3 cowpea (corresponding to LC 1 , LC 10 , LC 30 , LC 50 and LC 95 ) for 40 days, after which the physical properties of the cowpea were analyzed. The degree of infestation increased considerably with the reduction in AITC concentration, as did the water content and electrical conductivity. The germination percentage and apparent density decreased with the reduction in AITC concentration. The LC 10 sublethal concentration reduced reproduction in C. maculatus and the degree of infestation of the cowpea after 40 days of storage. AITC inhibits the development of C. maculatus and helps maintain the physical properties of the cowpea, thereby representing an alternative to the use of traditional insecticides and showing potential for the control of insect pests in stored grain.
