Interest in using hermetic technologies as a pest management solution for stored grain has risen in recent years. One hermetic approach, Purdue Improved Crop Storage (PICS) bags, has proven successful in controlling the postharvest pests of cowpea. This success encouraged farmers to use of PICS bags for storing other crops including maize. To assess whether maize can be safely stored in PICS ba...

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...

This study aimed to control lesser grain borer Rhizopertha dominica via using of Zingier officinale (ginger) and Helianthus annuus (sunflower) oils as protectant Tritium spp. The inhibition rates were 38.00, 28.98, 22.67 4.60% respectively when the wheat treated by 0.5, 1, 1.5and 2% sunflower oil while 35.50, 28.00, 7.25 3.25% same concentrations Z. oil. damage assessments decreased increasing ...

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 ...

BACKGROUND Drying is currently the most frequently used conservation method for cereal grain, which in temperate climates consumes a major part of process energy. Airtight storage of moist feed grain using the biocontrol yeast Pichia anomala as biopreservation agent can substantially reduce the process energy for grain storage. In this study we tested the potential of moist stored grain for bio...
