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.

Biology of Sitophilus oryzae (L.) on Stored Rice
Biological ForumThe rice weevil (Sitophilus oryzae L.) is a very destructive pest common in stored grains because of its polyphagous behaviour. For the effective management of the insect, its biology should be understood. So, the present study aimed to evaluate the biology of rice weevil was studied on stored rice variety “Lajawab” under laboratory conditions during ...

Effects of symbiotic status on cellular immunity dynamics in Sitophilus oryzae
Developmental & Comparative Immunology, 2017Many insects maintain intracellular symbiosis with mutualistic bacteria that improve their adaptive capabilities in nutritionally poor habitats. Adaptation of insect immune systems to such associations has been shown in several symbiotic consortia, including that of the rice weevil Sitophilus oryzae with the gammaproteobacterium Sodalis pierantonius ...

EFFECT OF INTERCOMPETITION ON THE POPULATION GROWTH OF SITOPHILUS ORYZAE
1986Intercompetition had a sig ificant role in the population behaviour of S. oryzae. The po ulation growth of S. oryzae was highest when it was allowed to multiply in association with R. dominica.Its population growth was lowest when it was kept along with S. granarius and R dominiea. However, the multiplication behaviour of S.

Evaluation of Medicinal Plant Powders for Control of Sitophilus oryzae in Rice (Oryza sativa)
UTTAR PRADESH JOURNAL OF ZOOLOGYCereals, specially rice is vital dietary staples, supplying crucial nutrients like carbohydrates for energy, dietary fiber for good digestion, proteins, vitamins for metabolism, and minerals like iron and magnesium. They serve as key sources of energy for billions globally, underpinning food security and economic stability.

Biology of Sitophilus oryzae (Coleoptera) on stored Wheat Genotypes
Research Journal of Pharmacognosy and PhytochemistryThe biology of five different genotypes of rice weevil in stored wheat was studied in the laboratory of PG Department of Botany, Jai Prakash University Chapra (Bihar). The study found that the different developmental stages of the rice weevil were longer in winter than in summer. HUW 214 recorded the lowest incubation period of 7.53 days, while HI 8498

Properties of glycylglycine dipeptidase from Sitophilus oryzae (L.)
Journal of Insect Physiology, 1965Abstract 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 ...
