Caraka Tani: Journal of Sustainable Agriculture, 2022 Weevil (Sitophilus zeamais Motsch.) is a vital arthropod pest of maize (Zea mays L.) grains and flours in traditional storage systems. The pest bore holes into stored grains reducing their nutrient contents germination potentials and contaminating ...

Resistance of maize to the maize weevil: I. Antibiosis
African Crop Science Journal, 2001 Resistance to damage by maize weevil (Sitophilus zeamais Motsch.) is critically important to subsistence farmers who typically store maize grain on-farm. To evaluate grain's antibiosis effects to weevil, 18 inbred lines, six each from Southern Africa, Mexico and CIMMYT-Zimbabwe were mated in sets, according to a North Carolina Design II.

Dust to weevils, weevils to dust: maize weevil personality and susceptibility to diatomaceous earth
Journal of Pest Science, 2015 The role of behavior in insecticide susceptibility is broadly recognized, in addition to the physiological effects of insecticides. Curiously, the recognition of the importance of behavior does not extend to the control by physical agents, like inert dusts such as diatomaceous earth (DE).

Resistance of maize to the maize weevil: II. Non-preference
African Crop Science Journal, 2001 Although there have been significant advances in improving maize for grain yield, progress in developing varieties resistant to the maize weevil (Sitophilus zeamais Motsch.) has been limited. In this study, fifty-two hybrids were evaluated against the maize weevil for non-preference in free choice experiment to study gene action determining inheritance

Spatial distribution and losses by grain destroying insects in transgenic corn expressing the toxin Cry1Ab. [PDF]
PLoS ONE, 2018 Insect pests are one of the factors that most impact plant yield. The magnitude of the losses and the spatiotemporal pest distribution in crops is a result of their interactions with the environment.
