Agriculture is the main occupation of Indian people. Farmers encounter the problems of various types of insect pests that harm crops and result in loss of productivity each
Therefore, it is necessary for farmers to use pesticides to prevent crop damage.
However, when pesticides are used in large quantity, they cause adverse impacts on people, animals and the environment. Instead of using pesticides, the government has to support other ways to prevent insect pests, including the use of biological agents and some insects etc

Farmers Must know that by Attracting and Killing one adult moth or Insect they control around 300-400 insect progenies through them.
Once the insect population in the light traps crosses a certain limit the farmer can decide on the type of pest management they have to take up.
By keeping a light trap, one for every half an acre right from the beginning of planting the farmer can control almost all the insect pests that are trying to attack the crop.
The light trap has undergone lots of changes from its simple beginning as a kerosene lamp kept in front of a cloth sheet or water container to electrically operated ones to battery operated now.
The ordinary light trap consists of an electric bulb emitting yellow light as attractant and a funnel to direct lured insects into a container containing water
