The butterfly called Pazarsta has great damage in the artasoros. This lepidopter razes the eggs and the caterpillars extracted from it destroy corn.

One of the ways to deal with this problem is by using an insect called tricogram vase parasite. This small hymenopter of one millimeter places its eggs in the laying ones. Once the eggs are laid, those of the jar are also damaged.

This parasite only destroys the enemy, because it does not harm the rest of favorable insects. In addition, the laboratory is easily produced and is expected to use 25,000 hectares of maize in Europe this year.
