A method to prevent attack of "Mandari", a kind of insect that destroys tender coconuts.

Hanging two plastic bottles (200 mg. capacity) with the help of a strong plastic yarn or twine yarn filled with kerosene would prevent the insecticide.

Take two plastic bottles with capacity of 200 ml.

Tie one end of a plastic string to the neck of one bottle. The bottles should be open. Someone should climb up the coconut tree to place the yarn at the neck of the tree, little away from the flower bunch and tender coconuts. Take the yarn through one of the leaf stems allowing the bottle to hang freely at one side. Another bottle can be tied to the other end of the string standing at ground level. Fill 75% of both the bottles with kerosene. By pulling the string make the bottles hang straight below the neck of the coconut tree and tie the string firmly onto the tree. The smell of kerosene generated by the swinging action of these bottles is enough to keep the Mandari insect away. Kerosene is to be replaced every week by opening the string and getting the bottles down.
