English abstract During March 2000, nymphs and adults of the cyrtocorid bugs Cyrtocoris egeris Packauskas & Schaefer and C. trigonus (Germar) were observed on two different plants at two different localities. In Brazil (Londrina, Paraná State) adult C. trigonus were found feeding on stems of the weed plant arrow leaf sida, Sida rhombifolia L. (Malvaceae). Despite egg deposition in the laboratory, nymphs did not develop on this plant. In Argentina (Reconquista, Santa Fé Province), nymphs and adults of C. egeris were observed feeding on immature soybean [Glycine max (L.) Merrill] pods. Under laboratory conditions, nymphs of neither species could be reared beyond the third instar
Portuguese abstract Durante o mês de março de 2000, foram coletados adultos dos percevejos cirtocorídeos Cyrtocoris egeris Packauskas & Schaefer e C. trigonus (Germar) em duas espécies de plantas e em dois locais distintos. No Brasil (Londrina, PR) adultos de C. trigonus foram observados alimentando-se em hastes de guanxuma, Sida rhombifolia L. (Malvaceae). Apesar de as fêmeas terem ovipositado em laboratório, as ninfas não sobreviveram nesse alimento. Na Argentina (Reconquista, Província de Santa Fé), adultos e ninfas de C. egeris foram observados alimentando-se em vagens imaturas de soja, Glycine max (L.) Merrill. Nas condições de laboratório utilizadas, as ninfas não conseguiram se desenvolver além do terceiro instar
