Estimates of the damage caused in maize grain by the attack of Sitophilus oryzae (L., 1763) (Coleoptera: Curculionidae). The female uses strong mandibles to chew a hole into a grain kernel after which she deposits a single egg within the hole, sealing it with secretions from her ovipositor.

Control of weevils involves locating and removing all potentially infested food sources. Storage insects of basic food grains in Honduras. Raised levels of carbon dioxide are known to be toxic to many insect species, but S. oryzae has previously been shown to be one of the more tolerant species to this treatment. Disturbance of the grain causes adult Sitophilus spp. Cultural Control and Sanitary Methods A very high incidence of sterility was induced in the adults emerged from pupal exposures at 40°C (Sharma et al., 1997).Beckett et al.

Relative resistance of some sorghum varieties to the rice weevil, Sitophilus oryzae (Linnaeus) (Coleoptera: Curculionidae). For a distribution map, see S. zeamais data sheet. It is not yet known whether these relationships with the form of rice hold true throughout the tropics, but imports of milled rice into the UK from many countries are much more frequently infested by S. zeamais than by S. oryzae.

The activity of some compounds extracts by Allium on stored-product insects Oryzaephilus surinamensis (L.), Sitophilus oryzae (L.) and Tribolium castaneum (Herbst). Weight loss during storage (4-5 months) reached 30%, and most damage was caused by S. oryzae. Assessment of losses due to insect pests under wheat storage practices in semi arid region. In Egypt, weight losses attributable to S. oryzae and S. granarius in grain stored, under natural conditions, at 25°C and 70% RH, ranged from 56-74% in rice (Koura and El-Halfawy, 1972).Sorghum Trematerra and Girgenti (1989) investigated the influence of pheromone and food attractants on trapping S. oryzae. Although S. oryzae is primarily a pest of stored products, it can also attack cereal plants in the field. Population increase of S. oryzae was completely suppressed at 15°C, while a small number of F1 beetles of S. zeamais emerged. 111 (3), 1461-1468.

However, food preferences of the two species are variable; it is clear that S. zeamais is predominantly found associated with maize grain, whereas S. oryzae is associated with wheat. Brady, E.

Soft X-ray inspection of wheat kernels infested by Sitophilus oryzae.

Transactions of the ASAE, 46(3):739-745, Kestenholz C, 2001. In stored maize, heavy infestations of these pests may cause weight losses of up to 30-40%, although losses are commonly 4-5%. Subsequent infestations in storage result from the transfer of infested grain into stores or from the pest flying into storage facilities, probably attracted by the odour of the stored grain.
