Ecological aspects of lepidopteran caterpillar parasitoids from Caryocar brasiliense Camb. (Caryocaraceae) in a cerrado sensu stricto of Central Brazil

Abstract: This study quantified parasitoid occurrence on five lepidopteran caterpillars species that use Caryocar brasiliense as host plant, trying to verify if there was a direct relationship between host abundance and the proportion of parasitism; if leaf shelters served as cues or protection from parasitoids; if host size influenced the proportion of parasitism, and if attacks by Diptera were more frequent than by Hymenoptera. Searches for external folivorous caterpillars were carried out in an area of cerrado sensu … Show more

“…shelter builders and external feeders) can strongly influence the risk of parasitism (Gentry & Dyer 2002, Hawkins 1994) though conflicting results have been reported. Studies from tropical rain forests suggest that shelter builders suffer higher parasitism, in particular by parasitoid flies, compared with external feeders (Gentry & Dyer 2002) yet the opposite trend was found in a seasonal Brazilian cerrado (Rodovalho et al 2007). We therefore also tested the hypothesis that forest seasonality and feeding niche influences caterpillar abundance and susceptibility to parasitism.…”

“…A riqueza e abundância de espécies de parasitoides de Braconidae no presente estudo foram superiores aos da família Ichneumonidae. Parasitoides destas famílias são comumente relatados no Bioma Cerrado do Distrito Federal, como também em outras regiões, em uma ampla cultivar de culturas Rodovalho et al, 2007).…”

“…Para lepidópteros tropicais, especialmente espécies do cerrado, o nível de parasitismo larval acompanha a abundância de seus hospedeiros (Morais et al 1999, Rodovalho et al 2007 presente estudo e avaliados numa escala mais ampla, é polífaga . O sucesso para manutenção de uma dieta tão ampla como a polifagia não é conclusivo para os licenídeos.…”

“…A disponibilidade de alimento é também um fator chave para a ocorrência de herbívoros florais (Piña et al 2010 (Braby 1995, Muniz et al 2012. A sazonalidade é uma característica marcante em lagartas registradas em ambientes tropicais como o Cerrado, padrão predominante em espécies folívoras (Rodovalho et al 2007, Scherrer et al 2010, Diniz e tal. 2012) e praticamente desconhecido para lagartas florívoras como os licenídeos A fórmula usada foi D = ∑ n(n-1)/N(N-1), onde n se refere à abundância total de cada espécie e N é a soma das abundâncias de todas as espécies de licenídeos (Brower & Zarr 1984…”
