Stored Grain Pests and Current Advances for Their Management

Abstract

During the offseason, when fresh food is not available, humans have to consume stored grain food. Unfortunately, these stored grains are later infested with many pests. Foods stored in bags and bins are very much susceptible to infestation with several pests which can cause extensive post-harvest losses, spoilage, and less demand in markets, causing a huge economic crisis. Hence, successful management of stored grain pests becomes necessary to prevent these from insect pests. Current approaches for their management are one of the promising goals, as it includes preventive practices, monitoring, sanitation, and identification of main pathogens. Different management strategies of all the common stored grain pests viz. grain weevils, grain borers, grain moths, flour moths, mealworms, grain and flour beetles, booklice, mites, and parasites are enlisted here.

Biofabrication of Microbeads Infused with Acorus calamus Oil and Eucalyptus Extract for Sustainable Stored Grain Pest Management

“…Among these troublesome stored insect pests, the red flour beetle (Tribolium castaneum), rice weevil (Sitophilus oryzae), and bean weevil (Acanthoscelides obtectus) stand out as the most notorious offenders. These insect menaces are well-documented for their capacity to inflict both quantitative and qualitative harm on food grains . Infestations by these pests not only lead to significant grain losses but also create conditions conducive to elevated temperature and moisture levels.…”

Effects of different cowpea cultivars on some biological parameters of the cowpea seed beetle, Callosobruchus maculatus (Coleoptera: Chrysomelidae)

“…Stored grains are infested by different insect pests mainly coleopteran and lepidopteran pests [2]. These pests induce damage to the grains not only in the field but also in the stored area resulting in both qualitative and quantitative losses [3]. It has been estimated that between twenty-five and thirty percent of the world's grain crops are lost each year during storage because of the various types of pests that can affect the quality of the grains and the unsuitable facilities used by the farmers [1].…”

Multiple Pesticide Resistance in Rust-Red Fluor Beetle (Tribolium castaneum, Herbst 1797) from Northern Nigeria is Probably Driven by Metabolic Mechanisms

“…2 is a serious, cosmopolitan pest of stored grains and grain products in tropical and subtropical regions of the world [5], shown to destroy not only maize, wheat, and other granaries, but also rice bran, oilseed, oil cake, nuts, dried fruit, spices, chocolate, and even bones of animals [6].…”
