“…This resistance is influenced by biophysical, biochemical and genetic factors, including kernel hardness, pericarp thickness/thougness, phenolic compounds, enzymes and structural components of the kernel (Akpodiete et al, 2015;García-Lara et al, 2004L opez-Castillo et al, 2018;Saulnier and Thibault, 1999;Sen et al, 1994). The level of resistance is often assessed by the Dobie Index of susceptibility, which defines a cultivar as highly resistant, moderately resistant or susceptible (Demissie et al, 2015;Dobie, 1974;García-Lara et al, 2007). From an evolutionary perspective, resistance traits are influenced by plant and insect coevolution and/or artificial plant selection (Sharma and Ortiz, 2002;Simms and Fritz, 1990).…”

“…Anatomical barriers of the kernel, such as the pericarp thickness/ toughness, kernel hardness and endosperm vitreous have been directly correlated with the level of resistance (Akpodiete et al, 2015;Classen et al, 1990;García-Lara et al, 2004;Serratos et al, 1987). Studies performed in QPM varieties concluded that kernel hardness per se is not a sole factor influencing susceptibility to S. zeamais infestation (Demissie et al, 2015;Oloyede-Kamiyo and Adetumbi, 2017). Pericarp thickness/toughness is a biophysical trait closely associated with cell wall reinforcement.…”

One of the main challenges for the 21st century is ensuring global food security. Today, maize is the largest staple crop produced worldwide. Postharvest primary insect pests, especially the maize weevil (Sitophilus zeamais) and the large grain borer (Prostephanus truncatus) cause food-grain losses during storage up to 40% of total production, mainly in developing countries. Alternatives for pest management have been explored, including the implementation of hermetic storage structures and the application of chemical insecticides. Nevertheless, in low-income regions, both strategies are rarely accessible to smallholders. Modern breeding programs have endeavored to develop insect-resistant varieties, which diminish postharvest pest losses. In this review, we report the current status and advances in maize kernel-pest interactions, the bases and mechanisms of kernel resistance and their biotechnological perspectives. We demonstrate that the comprehension of resistance mechanisms has been fundamental for the development of new productive and resistant varieties, representing a sustainable alternative for developing countries. Finally, we analyse the biotechnological perspectives of natural kernel resistance in global food security.

“…Different management options including the use of chemicals, botanicals, cultural, host resistance and integrated pest management (IPM) have been recommended (Demissie et al, 2012b). Previous screening works identified a number of maize germplasm with moderate to high level of resistance to this insect pest (Demissie et al, 2012b(Demissie et al, , 2015. On the other hand, some of the popular commercial hybrid cultivars like "BH140" and "BH540" are susceptible to the maize weevil and farmers usually suffer from huge losses in their maize grain storage.…”

Biotic stresses are recently evolving very rapidly and posing significant yield losses of maize production in Ethiopia. A number of high yielding maize hybrids, initially developed as tolerant/resistant, have been taken out of production due to their susceptibility to major maize diseases. Furthermore, recent disease and insect pest epidemics have clearly shown the importance of breeding maize for biotic stresses and study the genetics of resistance to the major maize disease pathogens, insect pests and parasitic weeds. This paper gives the general perspective of the major biotic maize production stresses in Ethiopia and the interventions made locally and globally to control these stresses using host resistance. More emphasis was given to grey leaf spot (GLS), turcicum leaf blight (TLB), common leaf rust (CLR), maize streak disease (MSD), maize lethal necrosis (MLN), maize weevil, stalk borers, fall armyworm and Striga. Approaches to conducting genetic analysis and achieving durable host resistance to these stresses, where applicable, are discussed. This information will be used for breeders, private and public maize seed and grain growers who are targeting to operate in Ethiopia and Eastern Africa.

“…Es en estas condiciones de almacenaje donde diversos insectos se alimentan del grano y causan pérdidas económicas (Safitri et al 2018). El gorgojo del maíz, Sitophilus zeamais (Motschulsky) y el barrenador grande de los granos Prostephanus truncatus (Horn), son las plagas más importantes del maíz almacenado (Birkinshaw & Smith, 2000;Ribeiro et al 2007;Demissie et al 2015) ya que causan pérdidas de hasta del 30 % (Martínez et al 2013). Para aminorar los daños en granos almacenados se utilizan métodos de control físicos (temperaturas extremas, atmosferas controladas) y métodos químicos (fosfina), éstos últimos pueden causar efectos adversos en el humano como ampollas, dolor de cabeza, mareos, bronquitis y problemas motores, entre otros (Reyna et al 2012).…”

El objetivo de esta investigación fue evaluar en condiciones de laboratorio el efecto de extractos de plantas asociadas al cultivo del maíz, para el control de Sitophilus zeamais (Coleoptera: Curculionidae) y Prostephanus truncatus (Coleoptera: Bostrichidae) en granos de maíz almacenado. Para los extractos etanólicos y por infusión se emplearon plantas completas en la mayoría de los casos. Para seleccionar los mejores extractos vegetales para el control de estas plagas, primero se realizaron pruebas de olfatometría, posteriormente se efectuó el experimento de laboratorio, impregnando granos de maíz almacenado en un diseño completamente aleatorio con 10 tratamientos y aplicaciones a las 24, 48 y 72 h. Los principales resultados mostraron que para S. zeamais la mayor mortalidad la produjo la infusión de Bromus cathartiucus 57.5%) seguido por el extracto etanólico de tabaquillo Nicotiana glauca (47.5%). En el caso de P. truncatus también el extracto en infusión de B. catharticus produjo un 70% de mortalidad y un 62.5% con el extracto etanolico de Reseda luteola. De acuerdo con estos resultados, los extractos de estas plantas podrían usarse para el control de S. zeamais y P. truncatus en un programa de manejo ecológico de plagas de maíz almacenado.
