Objetivou-se avaliar o efeito da utilização de fosfina, associada a uma atmosfera rica em dióxido de carbono (CO2), no controle efetivo do inseto Rhyzopertha dominica (F.) em todas as suas fases de desenvolvimento. Para isso, foram realizadas fumigações com atmosfera sintética contendo 21% de CO2 e 79% de N2 associada a níveis reduzidos de fosfina (0,25, 0,50 e 0,75 g m-3). Para posterior comparação dos resultados, foram realizados dois tratamentos com ar ambiente associado às dosagens de zero e 1,00 g m-3 de fosfina. Todos os tratamentos foram realizados em três períodos de exposição (24, 72 e 120 horas), à temperatura de 29°C e umidade relativa de 60%. A análise dos resultados permitiu concluir que o aumento no período de exposição resultou no aumento da eficácia dos tratamentos em atmosferas sintética e ambiente. O controle efetivo de todas as fases do inseto foi obtido, em geral, com 0,50 e 0,75 g m-3 de fosfina + CO2, em período de exposição de 120 horas. Ovos e adultos foram as fases mais suscetíveis, e pupa, a mais resistente.
