Nymphalinae, Nymphalini, Papilio dirce, PapilionoideaAbstract
The Atlantic Forest biome includes the middle region of the Zona da Mata (MRZM) in southeastern Minas Gerais, Brazil. Cecropia hololeuca Miq. (Rosales: Urticaceae) is an arboreal plant endemic to Brazil. Species of Colobura Billberg (Lepidoptera: Nymphalidae) are common in forested habitats in the Neotropical Region. The aims of this study were to report damage by C. dirce dirce L. larvae on C. hololeuca in the MRZM, and to review host plants of Colobura spp. Two hundred fifty-two larvae were found damaging twenty 50 cm tall C. hololeuca plants on the campus of the “Universidade Federal de Viçosa” in Viçosa, Minas Gerais, Brazil, and brought to the “Laboratório de Controle Biológico de Insetos (LCBI).” Adults and exuviae of these larvae were deposited at the LCBI and identified in the “Departamento de Zoologia” of the “Universidade Federal do Paraná” in Curitiba, Paraná, Brazil, as C. dirce dirce. This is the first report of this lepidopteran on C. hololeuca in the MRZM. Seventeen species from 6 plant families have been reported as hosts for C. dirce dirce.
Sumário
O bioma Mata Atlântica inclui a região média da Zona da Mata, na parte sudeste de Minas Gerais, Brasil. Cecropia hololeuca Miq. (Rosales: Urticaceae) é uma planta arbórea endêmica ao Brasil. Espécies de Colobura Billberg (Lepidoptera: Nymphalidae) são comuns em habitats florestais na região Neotropical. Os objetivos deste estudo foram relatar danos causados por lagartas de C. dirce dirce L. sobre C. hololeuca na região média da Zona da Mata e revisar as plantas hospedeiras de Colobura spp. Duzentas e cinquenta e duas lagartas foram encontradas danificando vinte plantas de 50 cm de altura de C. hololeuca no campus da Universidade Federal de Viçosa, em Viçosa, Minas Gerais, Brasil, e trazidas para o LCBI. Adultos e exúvias dessas lagartas foram depositadas no Laboratório de Controle Biológico de Insetos (LCBI) e identificados no Departamento de Zoologia da Universidade Federal do Paraná, em Curitiba, Paraná, Brasil, como C. dirce dirce. Este é o primeiro relato deste Lepidoptera sobre C. hololeuca na região média da Zona da Mata. Dezessete espécies de seis famílias de plantas têm sido relatadas como hospedeiras de C. dirce dirce.
