Differential net food utilization by larvae of Sitophilus oryzae and Sitophilus granarius
Journal of Insect Physiology, 1974Abstract The net utilization of a meridic diet by Sitophilus oryzae from the newly hatched larva to the pupa was more efficient compared with that of S. granarius . The artificial diet was highly digestible to both species, but S. oryzae converted 24·1 per cent of the ingested food into body substance compared with 12·4 per cent converted by S.

Vitamin requirements of larvae of Sitophilus oryzae
Journal of Insect Physiology, 1975Abstract 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.

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.

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.

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 ...

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 ...

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.
