Jomon pottery and maize weevils, Sitophilus zeamais, in Japan
Journal of Archaeological Science: Reports, 2020Abstract Recent research in Japan using the ‘impression method’ has revealed Jomon vessels containing a large number of plant seed impressions in the clay, including from soybean and adzuki bean seeds. Additional research has been published about a vessel with a large number of maize weevils (Sitophilus zeamais).

Is flint corn naturally resistant to Sitophilus zeamais infestation?
Journal of Stored Products Research, 2015Abstract 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. zeamais (Motschulsky), the maize weevil.

Humidity and Tactile Responses of Sitophilus zeamais (Coleoptera: Curculionidae)
Environmental Entomology, 1991In laboratory choice tests, maize weevils, Sitophilus zeamais Motschulsky, initially preferred lower humidities when given a choice of two humidities. The absolute difference in humidities and position on the RH scale had little influence on the response. After 24 h, weevils generally were hygropositive, which suggests that starvation or desiccation or

Abstract The responses of two field strains of Sitophilus oryzae (L.) and a field strain of Sitophilus zeamais Motsch. to lindane, malathion, ronnel and diazinon have been compared. Each strain was characterized by its response on exposure to insecticide-impregnated filter paper; lindane median lethal concentrations at 24 hr for S.

Abstract DNAs from the endosymbiotes of two species of grain weevils, Sitophilus oryzae and S. zeamais, were separated from host-weevil DNA and purified by cesium chloride gradient centrifugation. Endosymbiote DNA was identified by hybridization with a probe of the gene encoding the 16S rRNA of Escherichia coli.

Contribution to the morphology and ecology of Sitophilus zeamais Motsch. in Yugoslavia
Journal of Stored Products Research, 1973Abstract After we established the existence of Sitophilus zeamais in Yugoslavia in 1968, we examined the various morphological characters given in the literature in which this species differs from S. oryzae. In an experiment S. zeamais has infested maize in the field, but was unable to survive the winter in the field in Zagreb in any stage of ...

Properties of glycosidases from the maize weevil, Sitophilus zeamais
Insect Biochemistry, 1991Abstract A survey of glycosidase activity in adults of the maize weevil, Sitophilus zeamais Motschulsky, indicated a complex of enzymes qualitatively sufficient to hydrolyze the free di- and oligosaccharides in their cereal diets as well as the maltose and oligomaltodextrins produced by the action of α-amylase on ingested starch. Glycosidase activity

Oviposition plasticity in Sitophilus zeamais (Motsch.) (Coleoptera: Curculionidae).
Mededelingen (Rijksuniversiteit te Gent. Fakulteit van de Landbouwkundige en Toegepaste Biologische Wetenschappen), 2003The oviposition plasticity (term used here to refer to the phenomenon whereby some insects reduce egg laying in poor conditions and increase it when conditions improve) of Sitophilus zeamais, one of the most serious insect pests to maize during grain storage, was investigated in different food resources.
