Resumo
A broca-do-cafeeiro Hypothenemus hampei é uma das principais pragas devido aos danos causados aos frutos e a redução da produtividade. Atualmente o controle desta praga é realizado com produtos químicos, os quais causam grandes prejuízos à saúde humana e ambiental. Assim, alternativas devem ser pesquisadas visando diminuir o uso de agrotóxicos. O objetivo deste trabalho foi avaliar a ação inseticida dos pós inertes bentonita, caulim e TD no controle de H. hampei. O experimento foi dividido em dois testes, no primeiro os pós foram aplicados na forma sólida, no segundo os pós foram suspensos em água, ambos os tratamentos foram aplicados em folhas de café, colocadas em tubos de ensaio contendo dez brocas cada. Após oito dias avaliou-se a mortalidade. Os maiores níveis de controle foram obtidos com o pó inerte bentonita (100%) na forma sólida e com a TD (94%) em suspensão. Já para o caulim não foi observada diferença nas formas de aplicação. Os resultados demonstram o grande potencial destes pós no controle da broca.
The coffee berry borer Hypothenemus hampei is one of main coffee pests because of damage to fruits, causing productivity reduction. Currently the control of this pest is done with chemicals insecticides, which cause great harm to human health and the environment. Thus, alternatives must be researched to decrease pesticide use. The aim of this study was to evaluate the insecticidal action of inert dusts, bentonite, kaolin and diatomaceous earth (DE) in H. hampei control. The experiment was divided into two tests, in the first powders were applied in solid form and in the second, powders were suspended in water, both treatments were applied on coffee leaves, placed in test tubes containing ten borer each. After eight days mortality was evaluated. The highest control levels , were obtained with the bentonite (100%) in solid form and with DE (94%) in suspension. As for the kaolin there was no difference in the application forms. The results demonstrate the great potential of these powders to control the borer.
