Management ofSitotroga cerealellain stored cereal grains: a review

Abstract

The economic loss due to pest attack in stored commodities is a serious problem worldwide. About 200 insect species attack stored commodities. These insect pests are responsible for quantitative and qualitative losses in cereal grains. Among the stored grain pests, Angoumois grain moth, Sitotroga cerealella is considered as common, top of the list and most destructive pest of cereal grains. Its infestation starts in the standing crop and continues in storage. Although there are many control strategies, our need is some effective, cheap and readily available strategy for safe storage. This review presents different ways by which S. cerealella can be controlled. In this paper, a list of approaches is given which are used to improve the protection of stored grains against S. cerealella attack. These approaches include use of edible oils, containers, synthetic chemicals, agricultural waste materials, plant derivatives, bacterial protoxins, biopesticides, biocontrol enhancers and semiochemicals. If these tactics are followed as combined strategies in a compatible manner, they can provide us an integrated pest management programme for the efficient control of S. cerealella in cereal grains.

Quality of grain and oil of maize subjected to UV‐C radiation (254 nm) for the control of weevil ( Sitophilus zeamais Motschulsky)

“…Several factors affect the quality of maize grains during storage, such as grain moisture, temperature, relative humidity (RH) of air in the storage environment, the presence of fungus, and attack by pests (Paraginski, Vanier, Berrios, Oliveira, & Elias, ; Rehman, Habib, & Zafar, ). Pests are responsible for approximately 40% of the losses during grain storage (Bushra & Aslam, ). Weevils ( S. zeamais Motschulsky) are the main insect pest of maize grains, attacking both in the field and during storage (Fikremariam, Tadele, Stephen, Yoseph, & Stefan, ).…”

“…The use of radiation has been shown to be effective in controlling pests, causing little, or no damage to the grains (Bushra & Aslam, ). According to Hallman (), gamma radiation doses above 150 Gy were effective in controlling the pest Sitotroga cerealella by reducing the population's fecundity, decreasing the number of eggs hatched, and reducing larval growth; these effects were also inherited by the F1 progeny.…”

“…Pests are responsible for approximately 40% of the losses during grain storage (Bushra & Aslam, 2014). Weevils (S. zeamais Motschulsky) are the main insect pest of maize grains, attacking both in the field and during storage (Fikremariam, Tadele, Stephen, Yoseph, & Stefan, 2009).…”

“…The consumption of grains contaminated by chemical residues can lead to loss of reproductive potential, and in some cases cause the death of the animals. These disorders can also be observed in humans (Bushra & Aslam, 2014). Thus, integrated pest management has emerged to encourage and develop alternative methods to control pests.…”

“…Thus, integrated pest management has emerged to encourage and develop alternative methods to control pests. Studies on such methods include the use of diatomaceous earth, essential oil, ozone gas, pressurized carbon dioxide atmosphere, nonpressurized carbon dioxide atmosphere, biological control, and gamma radiation (Bushra & Aslam, 2014;Flinn, Kramer, Throne, & Morgan, 2006;Hansen, Hansen, & Vagn, 2013;Noomhorm, Sirisoontaralak, Uraichuen, & Ahmad, 2013).…”
