Rice is the most important durable food product for more than half of world’s population, as it very nutritious in terms carbohydrate containment and can meet a large part human caloric needs on daily basis. The sensitivity rice fortified with spearmint or basil was evaluated three stored insect species: Sitophilus oryzae (L.) (Coleoptera: Curculionidae), Rhyzopertha dominica (F.) Bostrychidae)...

The resistance to fumigant insecticides in stored-products insects is often recorded. Several factors influence the evolution of insecticide resistance. Among these, the frequency of applications and the migration of resistant populations are of primary importance for the stored-product insects. The aim of this study was to characterize the spectrum and investigate the status of phosphine resis...

We tested the hypothesis that the entomopathogenic fungus Beauveria bassiana would be more efficacious on oat cultivars that prolonged the immature developmental period of sawtoothed grain beetle, Oryzaephilus surinamensis (L.), a storage pest. However, percentage of reduction in progeny production was similar on whole 'Don' and 'Paul' oats treated with fungus, even though immature developmenta...

The potential for using spinosad to protect Australian grain from storage insects is discussed. Spinosad is produced from the metabolic by-products of a soil-dwelling bacterium, and is active against a range of insect species. Studies on relevant susceptible and resistant strains of a range of beetle and psocid pests indicate that spinosad efficacy varies greatly between species. Among the five...
