There are many diseases, weeds and pests that damage crops at every stage of agricultural production. Especially after the Second World War, with the production of many new pesticides and application machines, an intensive use of pesticides has emerged in the world. Accordingly, the damages of the plant protection products used on the environment and human health have started to be seen. The increase of people's awareness about safe food and environmental health makes it necessary to develop and use environmentally friendly methods in agricultural production. The plant protection will always exist. The plant protection should be based on the view of respecting the right to life of the living kingdom.

Research and education studies should be given importance for the widespread use of biological and biotechnical methods. Biological control can be simply described as "the use of beneficial organisms found in nature in the control against harmful organisms that cause economic losses in plant production".

It is known that 30-35% of the crop is lost on average when diseases and pests are not control in crop production. This loss rate can reach 100% in pest organisms that cause epidemics. Agricultural production is a difficult occupation. Despite all the difficulties, we need to see the fact that we are facing two major problems today, in addition to the existing plant protection problems. The most important one,

- Pesticide residue, the other is

- Increased costs of plant protection.

A crop production sector that could not solve these problems has no chance to be attractive, profitable and sustainable. The solution to these two problems is Integrated Pest Control, which is accepted all over the world. While Integrated Pest Management cannot be done without biological control, it is technically a necessity to make integrated pest management in an area where biological control is done.
