          Abstract

          Adults of Vatiga manihotae (Drake) were collected on cassava plantation (Manihotae esculenta Crantz), fécula branca variety, in Marechal Cândido Rondon, West region of Paraná state, Brazil, showing symptoms of fungi infection. Isolation and fungi identification procedures were performed. After that, Koch's postulates were used to prove the link between the fungus and insect and i noculated insects showed symptoms similar to the previously observed. Fungus was identified as Beauveria bassiana and caused the death of 14% of the insects 10 days after inoculation. This is the first record of natural occurrence of this species of fungus infecting V. manihote and further studies should be conducted to evaluated new isolates to control of this species.

          Adultos do percevejo de renda Vatiga manihotae (Drake) foram coletados em uma plantação comercial de mandioca (Manihotae esculenta Crantz), variedade fécula branca, em Marechal Cândido Rondon, Paraná, região Oeste do estado, Brasil, com sinais da presença de fungo sobre o corpo, sendo realizados procedimentos para isolamento e identificação do fungo. Uma vez obtido, foram utilizados os postulados de Koch para estabelecer uma relação causal entre o patógeno obtido e o inseto. Nos cadáveres observou-se a repetição da sintomatologia anterior que confirmaou a relação causal da doença. O fungo foi identificado como Beauveria bassiana e causou a morte de apenas 14% dos insetos após 10 dias de inoculação. Este é o primeiro relato natural da ocorrência desta espécie de fungo infectando V. manihote e novos estudos de seleção de isolados devem ser realizados.
