Vitamin requirements of larvae of Sitophilus oryzae

Journal of Insect Physiology, 1975
Abstract Improvements were made in the meridic larval diet for Sitophilus oryzae by replacing the minerals and vitamins supplied by dietary brewer's yeast and wheat germ with mineral and vitamin mixtures. The effects of different concentrations of individual vitamins were studied with the improved diet containing 20% casein.

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.

No oviposition plasticity in Sitophilus oryzae (L.) (Coleoptera: Curculionidae)

Journal of Stored Products Research, 1992
Abstract It would be advantageous for Sitophilus oryzae , both in culture conditions and in nature, to withhold egg laying in poor conditions if they could thereby lay more eggs when conditions improved ( oviposition plasticity ), as is known to occur in Callosobruchus maculatus .

Properties of glycylglycine dipeptidase from Sitophilus oryzae (L.)

Journal of Insect Physiology, 1965
Abstract The properties of the glycylglycine dipeptidase obtained from the Sitophilus oryzae were studied. It was observed that the enzyme has a pH optimum of about 7·6 and that the enzyme requires metal ions for its activity. The hydrolytic activity was found to be inhibited by the amino acids leucine and isoleucine, the chelating agents ethylene ...

Density-dependent fecundity in Sitophilus oryzae (L.) (Coleoptera: Curculionidae)

Journal of Stored Products Research, 1981
Abstract An experiment to assess the effect of population density upon the fecundity of Sitophilus oryzae (L.) is described. The range of densities employed is rather wider and somewhat lower than used in the earlier study of MacLagan and Dunn (1935).
