Record of defoliator lepidopteran in crabwood tree in Acre state and associated parasitoids

Abstract

The crabwood tree, Carapa guianensis Aublet, is a tree of significant socioeconomic importance especially for extractive communities in the North of Brazil, which exploit wood and, mainly, oil extracted from seeds. In January 2016, intense defoliation was observed in crabwood trees located in the municipality of Rio Branco, Acre state, Brazil, caused by lepidopteran caterpillars. Twenty pupa specimens were collected and placed in a screened cage to obtain adults. Five female moths emerged, which were identified as Acharia sp. (Lepidoptera: Limacodidae). In addition, two species of parasitoids were also captured, identified as Baryceros sibine (Cameron) (Hymenoptera: Ichneumonidae) and Conura sibinecola (Blanchard) (Hymenoptera: Chalcididae). Thus, the first record of Acharia sp. in crabwood tree in the state of Acre, as well as the first records of the two species of parasitoids associated with Acharia in the state of Acre, as well as in Brazil.
