Open-access Diabrotica speciosa (Ger.) (Coleoptera: Chrysomelidae): New Pest in Table Grape Orchards

Diabrotica speciosa (Ger.) (Coleoptera: Chrysomelidae): Nova Praga em Uvas de Mesa

AuthorshipSCIMAGO INSTITUTIONS RANKINGS

    We report for the first time the occurrence of Diabrotica speciosa (Ger.) damaging blooming clusters in grapevine orchards in Northwest Paraná State. On middle September, 2000, insects were found feeding on style, stigma and eventually on ovary. Up to 15 adults per cluster were observed. Insects feeding on stigma caused flowers aborting. In high population areas, clusters showed low number of fruits and were out of market standards.
