Abstract

Summary

The uncommon Cyrtocoris egeris Packauskas & Schaefer (Heteroptera: Pentatomidae) was collected in 2015 and 2016 in Francisco Beltrão Co. (26.07°S, 53.05°W), Paraná State, and in Mato Castelhano Co. (28.27°S, 52.18°W), Rio Grande do Sul State, Brazil. They fed and reproduced on plants of the Brazilian orchid tree, Bauhinia forficata Link (Fabaceae) and aggregated on branches. In the laboratory, nymphs did not develop on stems of seedlings of B. forficata or on a mixture of foods commonly used to rear stink bugs.

 

Sumário

O percevejo incomum Cyrtocoris egeris Packauskas & Schaefer (Heteroptera: Pentatomidae) foi coletado em 2015 e 2016, em Francisco Beltrão Co. (26.07°S, 53.05°W), estado do Paraná, e em Mato Castelhano Co. (28.27°S, 52.18°W), estado do Rio Grande do Sul, Brasil. Os percevejos se alimentam e se reproduzem na planta conhecida como árvore-orquídea brasileira, Bauhinia forficata Link (Fabaceae), mostrando um comportamento de agregação em seus ramos. No laboratório, as ninfas não se desenvolveram em hastes de mudas de B. forficata nem sobre uma mistura de alimentos comumente usada para criação de percevejos.
