Plant pests can be along with plants, organs and live plant products, seeds and plant organs that reproduce asexually (such as onions, tubers, seedlings, cuttings, cuttings, rhizomes and leaves), insects, vector animals, humans, wind and storms and rain, water and soil, agricultural and horticultural machinery and tools, means of transportation of plant products, wooden packages are transferred from native areas to non-native areas or from contaminated areas to non-contaminated areas.
If the climatic conditions in the new area are suitable for the growth and multiplication of plant pests, the plants of that area will be quickly infected or destroyed. Also, technical and executive problems in the field of tracking, identifying, eradicating or controlling such pests double their importance in terms of food security threats.

In the past and contemporary centuries, plant pests have caused countless damages to human life all over the world.
