Pest management in stored grain.

ABSTRACT :

 

Losses due to pest infestation in stored grain vary widely. They are greatest in warm countries, but probably average 10% worldwide. Techniques used for controlling pests in stored grain in Australia are described. Good storage practices (grain hygiene, and reduction in grain temperature and grain moisture) are fundamental to pest control. In Australia, around 70% of grain is fumigated, chiefly with phosphine either in sealed storages which permit prolonged exposures to lethal concentrations (one week minimum) or in a continuous application system which also permits prolonged exposures. Methyl bromide and carbon dioxide are used to a lesser extent. Around 30% of the grain is treated with grain protectant insecticides, currently chlorpyrifos-methyl plus methoprene.
