Resumo: Among the strategies for South American rice water weevil, Oryzophagus oryzae (Costa Lima) (Coleoptera: Curculionidae), integrated pest management is the increment of nitrogen fertilization in infested areas. Nevertheless the extra amount of N to apply is unknown. To address this question, an essay of nitrogen fertilization doses, with and without pest control, was carried out. Plots of 5 x 2m were delimited with PVC sheets in a irrigated rice field, in a factorial design with two pest control levels, five nitrogen fertilization doses (0, 40, 80, 120 e 160kg of N/ha) and four replications. The larval population, rice productivity and yield components were checked according to standard protocols. The productivity was influenced by the levels of pest control and the doses of nitrogen fertilization, but with no interaction between them. The extra amount of 40kg of N/ha replaces the effect of chemical control for the water weevil on the productivity, in an area where the mean dose of 80kg of N/ha were adopted for nitrogen fertilization.

Contudo, não há informação da quantdade adicional de nitrogênio a ser aplicada. Para responder a essa dúvida, executou-se um experimento de doses de adubação nitrogenada com e sem o controle da praga. Parcelas de 5 x 2m foram demarcadas com lâmina de PVC numa quadra de arroz irrigado em desenho fatorial com dois níveis de controle da bicheira-da-raiz, cinco níveis de adubação nitrogenada (0, 40, 80, 120 e 160kg de N ha-1) e quatro repetções. A população larval, a produtvidade do arroz e os componentes do rendimento foram aferidos conforme procedimentos padronizados. A produtividade foi influenciada pelos níveis de controle da praga e de adubação nitrogenada, porém sem interação entre ambos. A suplementação de 40kg de N ha-1 substtui o efeito do controle químico da bicheira-da--raiz sobre a produtividade em uma área em que se adote a dose média de 80kg de N ha-1 de adubação nitrogenada.
