Avaliação da armazenagem de grãos utilizando blocos de cerâmica com resistência elétrica como equipamento modificador de atmosfera para o controle de insetos.

Abstract

The objective of this work was to evaluate the grain corn storage in the modified atmosphere with part of the air passing through the holes with electrical resistance in a refratarian ceramic block in order to control Sitophilus spp insects species on three corn varieties (BR 201, BR 106 and BR 451). It was observed that the action of the modified atmosphere in this case did not killed the insect but it controlled the insect by inhibiting their development. The variety BR 451 was more infested by insects.
