Conteúdo: | Among the three temperatures tested high temperature is more favorable for aphid transmission of banana bunchy top virus (BBTV) to banana plantlets than low temperature. When banana aphids (Pentalonia nigronervosa Cog.) on diseased plantlets were kept at 16oC for 1 month before being transferred to feed on healthy plantlets, the disease agent could not be transmitted. However, when the feeding of aphids on diseased plants was carried out at 16oC for only 2 or 24h, all the inoculated plantlets developed bunchy top symtoms. Transmission rate of BBTV was directly correlated with the number of viruliferous aphids feeding on the plantlets and is inversely correlated with age of host plantlets. About 53% of single viruliferous aphids were able to transmit BBTV when 1-month-old plantlets were used.
