Resumo: It is estimated that 10 % of post-harvest losses of grain are related to insect infestation in storage. Several control methods are studied, including the use of phosphine gas. This work aimed to study the mortality of Sitophilus zeamais (50 insects), Tribolium castaneum (20 insects) and Cryptolestes ferrugineus (20 insects) using phosphine gas at concentrations of 1 and 2 g m–3. Cylindrical chambers were used for the storage of corn and jars to hold the insects. The duration of the purge was five, seven and nine days for each treatment. Besides the mortality was also analyzed the concentration of phosphine gas inside the chambers and the emergence of insects in grain purged. The control treatment was free of fumigation. In all periods of purge, was obtained 100 % mortality for the three species studied, both concentrations of phosphine. The phosphine gas concentration has decreased over time and there was no emer- gence of offspring at 30 days. It is concluded that phosphine concentrations of 1 and 2 g m–3 is effective in controlling S. zeamais, T. castaneum and C. ferrugineus without producing offspring.

Diversos métodos de controle são estudados, entre eles o uso de gás fosfina. Este trabalho objetivou o estudo da mortalidade de Sitophilus zeamais (50 insetos), Tribolium castaneum (20 insetos) e Cryptolestes ferrugineus (20 insetos) com uso de gás fosfina nas concentrações de 1 e 2 g m–3. Foram utilizadas câmaras cilíndricas para o armazenamento dos grãos de milho e frascos de vidro para armazenar os insetos. A duração do período de expurgo foi de cinco, sete e nove dias para cada tratamento. Além da mortalidade analisou-se também a concentração do gás fosfina no interior das câmaras e a emergência de insetos nos grãos expurgados. O tratamento testemunha ficou livre de fumigação. Em todos os períodos de expurgo foi obtido 100 % de mortalidade para as três espécies estudadas, em ambas as concentrações de fosfina. A concentração de gás fosfina diminuiu ao longo do tempo e não houve emergência de prole no período de 30 dias. Conclui-se que a fosfina nas concentrações de 1 e 2 g m–3 é eficaz no controle de S. zeamais, T. castaneum e C. ferrugineus sem produção de descendentes.
