The fruit fly, whose scientific name is Ceratitis capitata , is a flying insect that, as its name suggests, feeds on the fruits of trees . But not only that, but it also leaves its larvae inside the persimmon, causing it to rot right away.

To do? Very simple: place several yellow sticky traps near the tree . Thus, once they are stuck to them, they will not be able to do anything. Another option is to cut a plastic bottle in half, pour in sugar or honey and water, and hook it to the tree with a rope.
