Given the complexity of practical usage controlled atmospheres for protection agro-commodities, several researchers have pointed out that there is not enough robust scientific documentation regarding inert gases their widespread application. Therefore, this work evaluated various regimes hypoxic and anoxic nitrogen control two key stored-product pests, in laboratory under field conditions silos...

The granary weevil Sitophilus granarius L. is a pest causing substantial damage to stored wheat worldwide, against which the elaboration of sustainable control methods has recently been gaining importance. Our objective was assess efficacy rapid atmospheric convection heat transfer method S. under laboratory conditions. We examined changes in adult mortality and progeny survival triggered by ef...

Flour mill fumigations are currently carried out with methyl bromide (MB). By 2005, this gas will be phased out in developed countries because it has been listed under the Montreal Protocol as a substance that depletes the ozone layer. Hydrogen cyanide (HCN) was used as the fumigant of choice for mills in the first part of the last century, and was then replaced by MB. Consequently, it should n...

Wheat, the main source of protein in human diet, is a staple food many countries. The yields and technological quality wheat grain depend on both yielding potential properties that allow its safe storage. To large extent, losses during storage are caused by pests. Grains 46 cultivars were used study (samples weighing 20 g each variety 10 replications), which development weevil Sitophilus granar...

This study was conducted to characterize farmers' post-harvest conservation practices and identify the different storage structures, main pests of cereals in stock, as well mode application insecticides protect seeds against infestations. To these practices, we have prepared a questionnaire answering characteristics population three provinces. The grain structures our region vary depending on l...
