New threat to orangesThis article was originally published in Foodnews
BRAZIL's São Paulo state has reported its first cases of citrus blackfly in several municipalities, according to the state's agriculture secretariat. The secretariat is imposing restrictions on the handling of citrus fruits in the affected regions, but it is unlikely (at this stage) that countries will impose restrictions on imports of fruit from the state, as most is sold in the form of orange juice. Blackfly can reduce an orange tree's yield by up to 80% by draining the sap from leaves. Its presence has been detected in other states such as Amapa, Amazonas, Maranhao, Para, Goias and Tocantins, all in Brazil's northern and centre-west regions closer to the Equator.
