Prepare a concentrated solution of 500 g of sugar in one litre of water and allow it to ferment. Place the fermented solution in open dishes at different locations between the rows of cotton. Add one or two drops of edible oil to the dish. Sarajbhai Sindha of the Saraj village in the Jambusar taluka in Bharuch district in Gujarat attracts insect pests of cotton through a sugar solution and edible oil to eliminate them. Sindha prepares a concentrated solution of 500 g of sugar in one litre of water and allows it to ferment. The fermented solution is placed in open dishes at different locations between the rows of cotton. One or two drops of edible oil are added to the dish. Practitioners say that adult insects (which can fly) are attracted towards this solution. The idea behind this practice is to kill the adult population and ultimately reduce the reproduction.
