Resumo. Horiola picta (Coquebert, 1801) (Hemiptera: Membracidae) is a secondary pest of Theobroma cacao L. (Malvaceae), a species of cocoa, in several regions of Brazil. It is found in young branches and cocoa fruits, where it lays its eggs in plant tissue, causing damage to plantations. Here, we report the first occurrence of H. picta for the state of Minas Gerais and its first record on Filicium decipiens (Wight & Arn.) Thwaites. Egg masses, nymphs, and adults of H. picta were observed from 2021 to 2024, with increasing colonization over the years. This finding highlights the potential risk of ornamental plants becoming hosts for agricultural pests.
