SUMMARY:

Parasitic plants complete their life cycle associated with the host, and may be hemiparasites or holoparasites. Many parasitic plants belong to the Loranthaceae family, order Santalales, and are popularly known as mistletoes, which use a specialized organ, known as a haustorium, to remove water and mineral salts from their hosts. The mistletoes can be affected by diseases such as anthracnose, caused by species of the genus Colletotrichum. The study of Colletotrichum species that infect parasitic plants can be used as alternatives for the biological control of these plants. However, few studies have been conducted focusing on this theme. Given the above, the objective of the present study was to identify the species of the genus Colletotrichum in parasitic plants in the municipalities of Maceió and Rio Largo, Alagoas. Ten isolates of Colletotrichum were obtained from parasitic plants of the genera Psittacanthus and Struthanthus. For cultural characterization, the colony color and the mycelial growth of the isolates were evaluated at 25ºC in four different culture media, namely BDA, SNA, cornmeal and oat. For morphological characterization, the length and width of conidia were measured. Pathogenicity tests were performed on leaves detached from the respective hosts, and all isolates proved to be pathogenic.
