Due to the research results in breeding, the rape currently occupiesan important place in the global economy as a source of vegetable oils used in food industry and especially in the creation of some alternative energy solutions (Palagacheva Nedyalka, 2006).\n The one – sided, unreasonable and excessive use of some chemical products has resulted the appearance, on the one hand, of the resistance phenomenon to certain pests at some chemicals, and on the other side of the pollution of the environment. These two phenomena have revealed that the crops protection against pests by applying a system based on a single method of control, rarely gives satisfactory results for a long time. These cases have resulted the development of integrated control systemsit is now widespread and accepted the idea of integrated control, meaning through this a harmonious combination of all factors that may have a role in preventing or limiting the pests destructive action. Its ultimate goal is not to eradicate the pest, but to reduce and maintain the populations of those species below the level that causes damages, below the economic threshold damage (ETD).\nKnowing these aspects at A.R.D.S. Secuieni, during 2010 – 2012, were conducted research, which aimed to establish the spread and faunal structure of useful organisms from winter rapeseed crops in the Central Moldavian Plateau climatic conditions and the analysis of some ecological parameters of useful insect species collected from the winter rapeseed crop in A.R.D.S. Secuieni activity area. \nDue to the research it was found that the most accurate method of collecting insects is the collecting method with the help of the yellow bowl type traps, which collect a wider range of insects.
