Physical and mechanical control were one of the methods to be used for reduciing the incidence of insect pests. Drying of grains before storage, handpicking of lice and collection and destruction of pest-infested plant parts were the routine methods that were employed since long.

Similarly, some legal measures were also adopted to overcome certain pests which were otherwise difficult to contain. FOr example, as early as , removal of cotton sticks by 1as august every year was made compulsory by law to minimise the incidence of pink bollworm on cotton in the erstwhile madras state. All these methods were improved and refined to enhance their efficiancy against various insect pests. In the history of the world, no century can match the population growth of the one that has just come to a close.

We entered the 20th centur with less than 2 billion people and left it with more than 6 billion.

The global population reached 6. It has been estimated that the population may grow even more in the 21 st century, but in a different manner.

The developed countries, which almost doubled their population size in the 20th century, will grow slowly or not at all. The new century's growth will occur almost exclusively in the developing countries.
