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.

Effects of carbon dioxide on the searching behaviour of the root-feeding clover weevil Sitona lepidus (Coleoptera: Curculionidae) [PDF]
, 2006 The respiratory emission of CO2 from roots is frequently proposed as an attractant that allows soil-dwelling insects to locate host plant roots, but this role has recently become less certain.

Protecting stored maize grain against the Sitophilus zeamais with rice husk ash
Julius-Kühn-Archiv, 2018 Maize weevil (Sitophilus zeamais) is an important insect that affect the maize grain on the field and in storage. There are several ways of controlling this insect but the most commonly used is the use of chemicals.

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.
