摘要

The discovery of the fungus Colletotrichum gloeosporioides living like a parasite on the O. praelonga in citric orchards, raise the possibility of its utilization on the control of this pest. The biological control, however, should be done with the certainty that the utilized microorganism will not provoke diseases in other cultures that are been cultivated near the orchards. Then, this work aimed to evaluate and compare the phytopathogenic potential of the C. gloeosporioides isolates, pathogenics of O. praelonga (CTAA1-5), with other C. gloeosporioides isolates (CCC and CCE), C. acutatum (CCA) and C. lagenarium, responsible by diseases of fruit in citrus post-harvest and postbloom, and by antracnose in pumpkin, respectively. The fungi were inoculated on banana, coffee, apple, peach, papaya and on the pumpkin leaves, with or without injury. The peach fruits were susceptive to all isolates tested at the two experimental conditions. The apple and the pumpkin leaves, when injured, also showed susceptibility. The banana, coffee, and papaya were not susceptive in both inoculation conditions.
