Ocorrência de Dyscinetus rugifrons Burmeister (Scarabaeidae: Dynastinae, Cyclocephalini) em plantios de Palmeira-Real-da-Austrália (Archontophoenix spp. H. Wendl. & Drude), no Vale-do-Itajaí, SC

Abstract

For the first time in the Vale do Itajaí, Santa Catarina State, was registered the occurrence of Dyscinetus rugifrons (Burmeister) attacking plantations of Archontophoenix spp. The insect was observed in the Barra do Sul city, causing damages in young plants. The attack caused plant death and in the surveyed area 45% of the plants were attacked. The importance in keeping Archontophoenix spp. plantations is that it is an alternative to palmito-juçara (Euterpe edulis) harvesting, a native specie that has its regeneration compromised for the illegal extrativism.
