Silo bag technology is used for storing grains in a hermetic plastic structure. The major limitation of this structure resistance to improper handling and external aggression, thus promoting pest incidence due alterations its internal atmosphere. In study, we developed biopesticidal silo consisting co-extruded three-layer film made polyethylene essential oil Mentha piperita (7% w/w) the inner l...

Levels of insect infestation, insect spatial distribution, and the relationship between the number of insect-damaged kernels (IDK) and the number of insects present in grain samples in three-hopper railcars transporting wheat from country elevators to a mill were studied. Six of eight sampled railcars were infested with more than two species of insects. The most abundant species collected were ...

An alternative to fumigants and insecticides for controlling stored-product insects in empty grain storage bins prior to filling is heat treatment, in which the temperature is quickly raised to a minimum of 50 1C and held there for 2–4 h. Effectiveness of heat treatment on empty grain storage bins was evaluated for five commercial propane and electric heat-treatment systems by measuring air tem...
