Resumo: | ABSTRACT: Empoasca kraemeri (Hemiptera: Cicadellidae) is a pest of the sweet potato crop. Its control demands applications of synthetic insecticides, which causes the emergence of pest resistance to these products and contamination of the environment. Thus, the use of essential oils is an alternative for insect control. However, the present study aimed to evaluate the bioactivity of Neem oil on E. kraemeri. The bioactivity of Neem oil on E. kraemeri was evaluated under laboratory conditions. To verify the effect of leaves of Ipomea potatoes were sprayed at concentrations 6.0; 3.0; 1.5; 0.75 and 0.25 ul L-1 supplied to adults. The controls were sprayed with distilled water. The design was completely randomized with six treatments and five replications with twenty insects per leaf. The experiment was maintained, in the laboratory, at 25 ± 2 ° C; RH of 50 ± 10% and photophase of 12. The extract caused adult mortality, reducing the survival of E. kraemeri. There was a mortality of 70% to 100%, demonstrating the contact action of the compound and its potential for control of the leafhopper. In view of the results obtained, it was possible to conclude that Neem oil caused significant mortality on adults of Cigarrinha E. kraemeri.

Seu controle demanda de aplicações de inseticidas sintéticos, o que causa o surgimento de resistência da praga a esses produtos e contaminação do ambiente. Desta forma, o uso de óleos essenciais apresenta-se como uma alternativa para o controle do inseto. Contudo o presente trabalho teve como objetivo avaliar a bioatividade do óleo de Neem sobre E. kraemeri. Foi avaliada a bioatividade do óleo de Neem sobre E. kraemeri em condições de laboratório. Para constatação do efeito folhas de Ipomea batatas foram pulverizados nas concentrações 6,0; 3,0; 1,5; 0,75 e 0,25 ul L-1 fornecidas a adultos. As testemunhas foram pulverizadas com água destilada. O deloneamento foi inteiramente casualizado com seis tratamentos e cinco repetições com vinte insetos por folhas. O experimento foi mantido, em laboratório, a 25 ± 2°C; UR de 50 ± 10% e fotofase de 12. O extrato causou mortalidade dos adultos reduzindo a sobrevivência de E. kraemeri. Houve mortalidade de 70% a 100%, demonstrando a ação de contato do composto e seu potencial para controle da cigarrinha. Diante dos resultados obtidos, foi possível concluir que, o óleo de Neem ocasionou significativa mortalidade sobre os adultos de Cigarrinha E. kraemeri.
