Development of Sitophilus zeamais Motsch. in WURLD wheat

Journal of Stored Products Research, 1973
Abstract WURLD wheat, a parboiled, lye-peeled product, was tested, along with untreated white wheat and pearled white wheat, and a hard red winter wheat bulgur, for susceptibility to the maize weevil, Sitophilus zeamais Motsch. The order of suitability of the wheats for multiplication of the weevils was pearled, untreated, bulgur and WURLD.

Radiographic studies of Sitophilus zeamais Mots. in wheat kernels

Journal of Stored Products Research, 1971
Abstract Ninety-nine wheat kernels infested by Sitophilus zeamais Mots., were radiographed daily, to study development from egg to adult and behavior of the insects within the kernels. Enlarged photographic prints were prepared from these radiographs to facilitate interpretation.

The susceptibility of triticale to post-harvest infestation by Sitophilus zeamais Motschulsky, Sitophilus oryzae (L.) and Sitophilus granarius (L.)

Journal of Stored Products Research, 1978
Abstract Indices of susceptibility of five cultivars of triticale, four of wheat, three of barley and three of maize to post-harvest infestation by Sitophilus zeamais Motschulsky were determined. The numbers of F 1 insects (from the same number of parents) developing on the triticale lines were a little under twice as many as developed on the ...

Is flint corn naturally resistant to Sitophilus zeamais infestation?

Journal of Stored Products Research, 2015
Abstract 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.

Jomon pottery and maize weevils, Sitophilus zeamais, in Japan

Journal of Archaeological Science: Reports, 2020
Abstract 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).

Lindane resistance in Sitophilus oryzae (L.) and Sitophilus zeamais Motsch. (Coleoptera, Curculionidae) in Queensland

Journal of Stored Products Research, 1965
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.

Humidity and Tactile Responses of Sitophilus zeamais (Coleoptera: Curculionidae)

Environmental Entomology, 1991
In 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

Purification of DNA from the intracellular symbiotes of Sitophilus oryzae and Sitophilus zeamais (Coleoptera: Curculionidae)

Insect Biochemistry, 1989
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, 1973
Abstract 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 ...
