It is estimated that the 2020/21 orange harvst of the citrus belt in the state of Sao paulo and Minas Gerais will be 286.72 million crates, 173,973,33 million productive trees in the belt's orchards alone, responsible for 61% of the world juice production , with annual turnover of US dollar 14 billion.
However , a global problem limits citrus orchards, Greenling, which was identified in Brazil in 2004 and according to the most current data raised by the same institution , currently 19.02% of trees in the southeast are contaminated by the disease, the only one of which solution is its removal and elimination to avoid contagion among other individuals in the orchards.
Research has turned its attention to many areas of knowledge in order to solve this problem ,one ecological technique is already real and effective, systematic release of the wasp , trichogramma pretiosum , egg parasite of the lepidopteran citrus Fruit Borer Gymnandrosoma aurantiana , via drone.
This realease is made in such a way that the wasps emerge from where they fell and look for an isolated egg placed in isolated fruits , where they would penetrate and only appear in the harvest when seome peeling , come acrooss the caterpillar between the buds , many will be lost .
