Tribolium confusum and Sitophilus oryzae are stored product pests found worldwide. Environmental damages, human health issues the emergence of resistance driving scientists to seek alternatives synthetic insecticides for its control. Under this scenario, plant secondary metabolites being increasingly studied as bioinsecticides because they renewable, natural, biodegradable, non-persistent in en...

Insect pests in stored wheat cause significant losses and play an important role in the dispersal of viable fungal spores of various species including aflatoxin producing Aspergillus parasiticus. The problem of insecticide resistance in stored insects and environmental hazards associated with fumigants and conventional grain protectants underscore the need to explore reduced risk insecticides t...

The stored-product insects are one of the major causes losses in stored cereals. Most control measures still rely on a synthetic pesticide usage, but due to its negative side effects goods, human health, and environment, there is an urgent need for alternative control. A natural formulation based diatomaceous earth (DE) SilicoSec®, enhanced with botanicals (essential oil lavender, corn oil, bay...

A web-based model was used to simulate the impact of aeration on population growth of the lesser grain borer, Rhyzopertha dominica (F.), and the rice weevil, Sitophilus oryzae (L.), in stored rough rice, Oryza sativa L., at Beaumont, TX. Simulations were run for each of 10 yr with 1 August as the start date; 31 December as the end date; beginning populations of 2.5 adults per metric ton (1000 k...

Identifying stored-product insects is essential for granary management. Automated, computerbased classification methods are rapidly developing in many areas. A hyperspectral imaging technique could potentially be developed to identify stored-product insect species and geographical strains. This study tested and adapted the technique using four geographical strains of each of two insect species,...

Oils extracted from Cymbopogon citratus, Lantana camara, Artemisia camphorata, and Imperata cylindrica plants were used as potential insecticides against the rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae). The phytochemical composition of isolated oils was identified by gas chromatograph-mass spectrometry (GC-MS). Oil contact toxicities evaluated adults S. oryzae. activities ac...

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)...
