RESUMO
Recently, Dictyla monotropidia Stål was observed feeding on plants of black sage (Cordia verbenacea Al. DC). The colonies of this insect were observed on abaxial surface of leaves, with nymphs and adults sucking the phloem sieve, causing spot, yellow aspect and leaf fall. D. monotropidia was already related as pest in other Cordia species in countries of Central and South America. Although, this is the first report of this insect attacking plants of C. verbenacea in Brazil.

Recentemente, observaram-se plantas de erva-baleeira (Cordia verbenácea Al. DC) sendo atacadas pelo percevejo Dictyla monotropidia Stål. As colônias foram encontradas na superfície abaxial das folhas, onde ninfas e adultos sugavam a seiva do floema, causando encarquilhamento, seguido de amarelecimento e queda de folhas. D. monotropidia já foi relatada como praga de outras espécies de Cordia em países das Américas Central e do Sul, entretanto, este é o primeiro relato do inseto atacando plantas de C. verbenacea no Brasil.
