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 ...

Abstract This study reports the efficacy of using CO2 against Sitophilus zeamais and Sitophilus oryzae as an alternative treatment to fumigation for rice stored in a rice mill in Portugal. The trials were conducted in a silo containing 40 tonnes of polished rice and in four hermetic big bags of 1 tonne capacity; two with paddy and two with polished ...

Nitrogenous excretory products of adults of Sitophilus oryzae and Sitophilus granarius
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1976Abstract 1. 1. The nitrogenous excretory products of adults of Sitophilus oryzae and S. granarius feeding on wheat were examined. 2. 2. Uric acid, hypoxanthine, xanthine, allantoin, urea, and amino N were found in the feces of both species. 3. 3.

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.

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.

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 ...
