Exploring Plant α‐Amylase Inhibitors: Mechanisms and Potential Application for Insect Pest Control

Biotechnology Journal, Volume 20, Issue 8, August 2025.
Graphical Abstract and Lay Summary In this study, we address the importance of α‐amylases in insect pests, the possible biochemical role of α‐amylase inhibitors in plant resistance to insect pests, the molecular relationships between plant α‐amylase inhibitors and insect α‐amylases, and the biotechnological potential of proteinaceous α‐amylase ...

Is Flint Corn Naturally Resistant to Maize Weevil Infestation? [PDF]

, 2014
Sitophilus zeamais (maize weevil) is one of the most destructive pests of maize stored in tropical and subtropical regions. This study determined the resistance of flint corn and dent corn to infestation by S.

Resistance of Tripsacorn to Sitophilus zeamais and Oryzaephilus surinamensis

Journal of Stored Products Research, 2002
One strategy that has been used to find germplasm for developing improved plant varieties is to test ancestral germplasm for the desired traits. Although the progenitors of commercial maize are not known, a hybrid (called Tripsacorn) developed from a perennial teosinte, Zea diploperennis, and eastern gamagrass, Tripsacum dactyloides, resembles the ...

Concentration of CO2 in Hermetic and Non‐Hermetic Storage and Effect on Incidence of Insect, Fungi, and Oil Quality of Corn Grain With Different Moisture Contents

Journal of Food Process Engineering, Volume 48, Issue 7, July 2025.
Storage conditions, time, and initial moisture content affect the temperature, relative humidity, and CO2 concentration of corn grains, as well as their quality parameters. This study helps to determine the optimal conditions for preserving the quality of grain and oil.

Responses to colour and host odour cues in three cereal pest species, in the context of ecology and control [PDF]

, 2015
Many insects show a greater attraction to multimodal cues, e.g. odour and colour combined, than to either cue alone. Despite the potential to apply the knowledge to improve control strategies, studies of multiple stimuli have not been undertaken for ...

Resistance of Tripsacorn-introgressed maize lines to Sitophilus zeamais [PDF]

Journal of Stored Products Research, 2015
Abstract The maize weevil, Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae), is one of the major pests of maize worldwide. We tested one Tripsacorn-introgressed inbred maize line and 42 hybrid combinations between eleven public inbred lines and 16 different Tripsacorn-introgressed inbreds for resistance to the maize weevil to investigate ...
