• Trap cropping involves planting small areas of crop or other species plants near the protected crop.
• The trap cropping must be done, after closely understanding the seasonal cycle.
• The insects are left to develop in the trap and are killed with pesticides, this process is beneficial, since the pesticides are not spread on the whole of the crop, and thus environment friendly and economically sound too.
• In this practice the trap may be of different species of plant or the same crop but planted in different time.
• For example: an early maturing variety of crop to be protected must be planted on say 8-10 percent of the field. And the main crop is of a late maturing variety. Now the early maturity of the early maturing variety species will attract the pests, they seek food and will lay eggs of the first generation. treatments of insecticides are made in the trap around 7 to 10 days after the emergence of first generation adults, in order to prevent infestations in main planting.
