BACKGROUND
• Quite often the cultural, physical, mechanical and other
agro-technology practices are not sufficient to keep the
insect pests below the level of economic losses.
•
Therefore, the chemical pesticides are resorted to both as preventive and curative measures to minimize the insect
pest damage.
• But chemical spray is to be minimized and should be need

the tendency of pest to develop field resistance.
