Summary in the original language of the document
O óleo de nim obtido da planta Azadirachta indica, e formulações contendo os fungos Metharizium anisoplae e Beauveria bassiana, foram empregados para o controle da cigarrinha das raízes Mahanarva fimbriolata em cultivo orgânico de cana-de-açúcar. A ação desses produtos foi comparada com a mortalidade natural do inseto, através de parcelas sem o emprego de inseticidas. O experimento foi realizado no período de março a maio de 2008, em um talhão de cana-de-açúcar da variedade RB 85 5536 conduzida no sistema orgânico, na região de Sertãozinho, SP. O delineamento estatístico utilizado foi parcelas subdivididas, com 7 tratamentos, 3 repetições e 4 épocas. Não foram observadas diferenças estatísticas significativas entre os tratamentos. A mortalidade natural variou de 55,5% a 80,81%. Isto sugere que a ação dos agentes ambientais seja suficiente para reduzir a incidência de cigarrinha, M. fimbriolata, sem o emprego de inseticidas.
Summary translation
The neem oil obtained from the neem tree, Azadirachta indica, and the formulations that contain the Metharizium anisoplae and Beauveria bassiana fungi were used to control the froghopper, Mahanarva fimbriolata, in sugarcane crops. The action of these products was compared with the insect natural mortality, through portions with untreated check. The experiment was performed in the period from March to May 2008, on a plot of sugarcane RB 85 5536 variety conducted in organic system, in Sertãozinho, São Paulo state, Brazil. It was used a statistic outlining in subdivided plots, with 7 treatments, 3 replications and 4 periods. Expressive statistic differences were not observed among the studied treatments. The natural mortality ranged from 55,50% to 80,81%. This suggests that the action of the environmental agents is sufficient to reduce the incidence of leafhopper, M. fimbriolata, without using of inseticides.
