How to control fruit fly in watermelon

The female fly lays eggs in soft fruits
The maggot comes out of these eggs and makes a tunnel in the fruit and eats the fruit’s pulp, which causes the fruit to rot.
The fruits become curved and become weak and separate from the vine.
On the damaged fruit, the egg keeps the fluid coming out from the given place, which later becomes a khurnt.
