(Sitophilus oryzae)


It resembles to S.granarius, but it has duller colours, deeper spots on the thorax and four patches of lighter colour on the back. It is 2,5-3,5mm long. Eggs are laid into the seed, like S.granarius, which the larvae feed in. It is more sensitive to low temperatures.

Female lays 300-400 eggs, life cycle lasts one month under high temperatures, and lives 3-6 months. S.oryzae, as opposed to S.granarius, can fly and infest cereals in the fields. Larvae can also feed on cereal products, as flour and adults can feed on bakery and confectionary products.
