The Fundecitrus research teams (Sao Paulo), in collaboration with the teams at UC Davis (California) and ESALQ (Sao Paulo) have identified a pheromone attracting the Asian psylla, the vector of the Asian variant of greening. This major step forward will facilitate the development of high-performance insect traps, helping limit the spread of the disease, which is good news! While the disease is better controlled in Brazil, with the proportion of infected trees dropping for the first time in 2017 from 17 % to 16 %, the number of detections has continued to increase in the far north of Argentina, Mexico and many other production regions. And while the Mediterranean is fortunate enough to have been spared, the vector of the African variant of the disease is spreading rapidly in Portugal. It has recently been detected south of Lisbon, less than 200 km from the major production zones of the Algarve and Huelva in Spain.
