The observations were made in a wheat crop located in NE Moldova, Romania. In characterizing the climate in the NE of Moldova, we rely on long-term meteorological observations from the Plant Protection Center. In order to achieve the research objectives, were used three experimental variants:1st variant, wheat after wheat; 2nd variant, wheat after sun flower; 3rd variant, wheat after corn. In wheat crops, 43 harmful species were reported, grouped into 3 categories: species that caused damage with an attack rate of 3-20%, even if chemical treatments were performed, species that produced a sporadic attack, under 1% and species reported only in cereal crops without causing damage. A new concept has emerged, namely integrated control, which can be defined as a form of applied ecology, dividing pest populations, predator and parasite populations on the other in agrobiocenosis.
