There are were made observations in 2008 year in the rape crops in the National Institute for Research and Development for the cultivation of potatoes and sugar beet (INCDCSZ) Braşov, in two experimental variants: V1 - rape culture in which no treatments have been either chemical or seed during the growing season; V2 - rapeseed crops to which the chemical treatments to prevent and combat pests. Within each variant were used to collect material 6 traps each soil type Barber. Of the material collected were retained species coleoptere which were then determined. The determinations made in version 1, untreated rape, it was found that the 271 copies of coleoptere belong to a number of 28 species, while in version 2 , where rape has been made in treatments during the growing season against pests were collected 411 samples of coleoptere belonging to 30 species. The species most commonly encountered in the two variants were: F. Phyllotreta atra, Meligethes aeneus F., Pterostichus cupreus L., Phyllotreta nemorum L ., and Amara eurynota Panza .. These species were also the highest number of copies. Uncommon species were Pterostichus vulgaris L., Baris chlorizans germ., Malachius bipustulatus L., Amara aenea De Geer, Harpalus laevicollis Heyden, Amara APRICARIA Payk., Amara familiaris Duft., Apion violaceum Kirby, Cantharis fusca L., etc.
