In milled rice stores, bag traps baited with brown rice have captured both species (Hodges et al., 1986). Ovcharenko M M, Solodilov A I, Kravchuk M A, 2004. The relative resistance of 36 improved and local sorghum varieties were also assessed in Nigeria (at Samaru) (Bamaiyi et al., 1998). Doses of Ú1.0 kGy resulted in 100% mortality within 3-6 days for S. granarius, and within 4 days for S. oryzae (Ignatowicz, 1997).

Acta Phytopathologica Academiae Scientiarum Hungaricp, 11(3-4):305-315, Rajendran S, Gunasekaran N, Muralidharan N, 2001. There may be some potential for the development of pest management strategies that favour the action of natural parasites.Botanical extracts Antenna (London). Tropical Stored Products Information, 25:44, Munyuli bin Mushambanyi T, 2003. Stejskal V, Kučerová Z, Lukáš J, 2004. Pest Management and Economic Zoology, 4(1/2):97-100; 5 ref, Thind BB, Muggleton J, 1981. 25 (1), 53-56. Sitophilus spp., particularly in the pupal stage, have a lower natural susceptibility to the fumigant phosphine and to carbon dioxide used in controlled atmosphere storage than do other species tested and thus inadequate treatments are particularly likely to result in some survival. Both S. zeamais and S. oryzae are commonly parasitized by pteromalids (and occasionally other Hymenoptera). An introductory study of storage insect pests in Iran. Evaluation of material from plants of medicinal importance in Malawi as protectants of stored grain against insects. Effect of neem; Melia azedarch (Linn) and Azadirachta indica (A. Juss) on the incidence of Sitophilus oryzae (Linn) (Coleoptera; Curculionidae) on stored paddy. Females with lateral lobes of internal, Y-shaped sclerite broader and rounded apically, more narrowly separated.S. Biharean Biologist. Distribution of Bacillus thuringiensis Berliner in samples from warehouse and insect cadavers. Blue aleurone-layered barleys produced slightly fewer progeny of S. oryzae than the white aleurone-layered barleys. Effects of carbon dioxide and phosphine mixtures on resistant populations of stored-grain insects. Field monitoring Sitophilus zeamais and Sitophilus oryzae (Coleoptera: Curculionidae) using refuge and flight traps baited with synthetic pheromone and cracked wheat. Hamel D, 2007. In India, stored rice (unhusked) samples, drawn from six districts of Himachal Pradesh, were infested with S. oryzae (69%); the average weight loss in storage was 2.11%, and ranged from 1.09% to 3.10% (Thakur and Sharma, 1996). A contribution to the study of store pests in Vietnam. Weight loss caused by development of Sitophilus oryzae (L.) and Sitotroga cerealella (Oliv.) on grain of different varieties of maize. Analysis of development rates of Sitophilus oryzae (L.) in five cereals of the genus Triticum. 75:iii + 63 pp. Efficacy of neem products against storage pests in maize.

Takahashi in 1928 and 1931 complicated matters by raising the small form to specific status as Calandra sasakii.

Research Bulletin of the Plant Protection Service, Japan, No. The larva develops within the grain, hollowing it out while feeding. 15 (2), 157-161. Although both species are capable of flight, S. zeamais has a greater ability and tendency to fly (Giles, 1969). Juss) against two serious pest species of stored products, Sitophilus oryzae (L.) and Tribolium castaneum (Herbst), through nano-emulsion formulations. Indian Journal of Entomology, 58(1):79-90; 12 ref, Clement G, Dallard J, Poisson C, Sauphanor B, 1988. 973072, Nelson SO, Bartley PGJr, Lawrence KC, 1998. Journal of Stored Products Research, 27(4):213-220, Wongo LE, Pedersen JR, 1990. The effectiveness of controlled atmosphere was verified using generators of inert gases, such as carbonic anhydride and nitrogen, for the disinfestation of wheat stored in vertical silos and horizontal stores (Contessi, 1999). Cahiers Agricultures, 5(1):39-42, Ganesalingam VK, 1977. Grain may be protected by the admixture of insecticide. No pest survived at environmental temperature 27°C and temperature of the cereal mass approx. The effect of feeding by larvae and adults of S. oryzae on the weight of rice and wheat grain was determined in laboratory tests. Korean Journal of Applied Entomology, 36(3):215-223; 28 ref, Benhalima H, Chaudhry M Q, Mills K A, Price N R, 2004. Journal of Economic Entomology.

Chem. The moisture content of infested grains was positively correlated with the level of infestation in all cases. ; their taxonomy, productivity, and resistance to Sitophilus zeamais. Indian Journal of Entomology, 53(3):494-502, Sharma PR, Thappa RK, Tikku K, Chand D, Saxena BP, 1997. Distribution of the related weevil species Sitophilus oryzae and S. zeamais (Coleoptera: Curculionidae) in farmer stored grains of China. Post radiation mortality of adults of the grain weevil, Sitophilus granarius (L.), and the rice weevil, Sitophilus oryzae (L.). Annals of the Entomological Society of America, 52:687-695, Forghani SH, Marouf A, 2015. Pericarp hardness was associated with resistance at low rates of infestation, but at higher infestation rates, carbohydrate content seemed to be more important.
