dc.descriptionThe drying and death of soursop seedlings (Annona muricata L.) were reported on Viveiro da Floresta in Rio Branco, state of Acre, Brazil, in March 2017. The seedlings were obtained from municipalities of Dona Euzébia, Minas Gerais state, and the seeds from Capixaba, Acre state, Brazil. Seedlings with dieback symptoms were taken to the Laboratories of Entomology and Phytopathology of Embrapa Acre and analyzed with a stereomicroscope. The thrips found were preserved in ethanol (70%), mounted on slides, and identified in the specialized literature. Moreover, the isolation of fungi from leaves and stems was performed, which were inserted on Petri dishes with a PDA medium. The insect was identified as Pseudophilothrips sp., and the fungi pertained to the genera Colletotrichum and Lasiodiplodia. The high infestation of thrips in soursop seedlings, related to the nutrition of insects, is probably associated with the entrance of opportunistic fungi. Thus, the fungi colonized already fragile plants by the initial attack of insects, causing the drying and death of seedlings. Foi observado secamento e morte de mudas de gravioleira (Annona muricata L.) depositadas no Viveiro da Floresta em Rio Branco, estado do Acre, Brasil, em março de 2017. As mudas eram provenientes dos municípios de Dona Euzébia, MG e de sementes provenientes de Capixaba, AC, Brasil. Mudas com sintomas de secamento de ponteiros foram trazidas aos Laboratórios de Entomologia e Fitopatologia da Embrapa Acre, onde foram triadas sob microscópio estereoscópio. Os tripes encontrados foram preservados em etanol (70%), montados em lâminas de microscopia e identificados com auxílio de literatura especializada. Ademais, foi realizado isolamento de fungos de folhas e hastes, os quais foram inseridos em Placas de Petri, contendo meio PDA. O inseto foi identificado como pseudophilothripssp. e os fungos como pertencentes aos gêneros Colletotrichume Lasiodiplodia. A alta infestação e tripes observada nas mudas de gravioleira, associada às injúrias causadas por sua alimentação, provavelmente estão associadas à entrada de fungos oportunistas. Assim, os fungos colonizaram as plantas, já debilitada s pelo ataque inicial desses insetos, causando o secamento e a morte de mudas.
