The accuracy of near-infrared spectroscopy (NIRS) for predicting the chronological age of adults of the rice weevil, Sitophilus oryzae (L.); the lesser grain borer, Rhyzopertha dominica (F.); and the red flour beetle, Tribolium castaneum (Herbst), three pests of stored grain, was examined. NIRS-predicted age correlated well with actual age of these three species. Age predictions in S. oryzae by...

This study aimed at evaluating commonly used maize varieties, collected from Melkasa and Bako Agricultural Research Centers and Haramaya University, Ethiopia, against the maize weevil Sitophilus zeamais Motsch., one of the most important cosmopolitan stored product pests in maize. A total of 13 improved maize varieties were screened for their relative susceptibility to S. zeamais. The Dobie ind...

The fundamental idea of IPM is to put nature’s own regulatory mechanisms to maximum use in order to prevent damage, which is in the best interest of manufacturers, society at large and the environment. However, Haines (2000) assessed stored products IPM still insufficiently developed at the end of the 20th century. Support to IPM development in stored agricultural products is the use of natural...

Wheat is at peak quality soon after harvest. Subsequently, diverse biota use wheat as a resource in storage, including insects and mycotoxin-producing fungi. Transportation networks for stored grain are crucial to food security and provide a model system for an analysis of the population structure, evolution, and dispersal of biota in networks. We evaluated the structure of rail networks for gr...

In the present review article various control methods for stored grain insects are discussed in detail and an emphasis was made to use non-chemical methods. Stored grain infestation is a very serious problem as various life stages of insects cause economic damage and deteriorates the quality of food grains and food products. There are number of stored grain insect pests that infest food grains ...

We evaluated the competition among stored-product psocid species by conducting two series of laboratory experiments. In the first series, three species of Liposcelididae were used: Liposcelis bostrychophila, Liposcelis decolor, and Liposcelis paeta. Five adult females of these species were placed in vials containing wheat, either alone or in all possible combinations of two species. The number ...

Green synthesis of nanomaterials is the most recent trend in nanotechnology since it takes into consideration sustainable development and waste recycling, produces high value materials. Furthermore, green excludes use or production toxic hazardous chemicals to environment. This work aimed zinc oxide nanoparticles (ZnO NPs) using pomegranate peels extract as a reducing capping reagent instead ch...
