The rape seed culture, occupy the first place among plants of the family Cruciferae protein meal, both by the production and by its high oil content. In European community countries, rape is cultivated on significant areas through the use of rapeseed oil in industry and agriculture. Research on entomofauna were made in rapeseed farm S.C. AGRO IND COM S.R.L. Botoşani fron 2011. The material was collected using soil traps Barber type. In totally, in the ecosystem of the year 2011 were collected 1184 samples. The species collected belonging to 7 orders: Diptera, Arachnidae, Hymenoptera, Coleoptera, Orthoptera, Homoptera and Heteroptera. The damaging fauna from the rape cultures belongs to the Coleoptera orders with the species Meligethes aeneus F., Phyllotreta atra L. and Phyllotreta nemorum F.; Diptera order, Anthomyidae families.
