The Lotus corniculatus has a great capability of autoinsemination, even in the conditions of a depasturage of a long time. Concurrently, the rusticity assures great qualities to the Lotus corniculatus, comparative with the other leguminouses such as, the lack of meteorisations production during the consumption under green table shape (Zamfirescu, 1965). The entomofauna knowledge of this crop plants represents one of the most important stage in realizing a integrated protection to obtain a production of superior quality and great quantity. Odontothrips loti Hal. is one of the most important pest of this crop, mekeing damage of 80% of the total yield production. The paper propose is to emphasize some experimental data concerning the effected investigations results wich deffine the influence of different parts of the body, upon the development of the adults of Odontothrips loti Hal. In realizing this porpoise the experimental fields was placed at S.D. Timisoara, after the standard method of location of the experiences, every lot had the length of 2 m and a latitude of 1 m. After the biometrical measurements it established that the head lenght is aproximately equal with his latitude, being a few broader (+0,07). The protorax lenght broader then long and the head and prothorax lenght excels the latitude of those two regions. The head and prothorax lenght represent cca 1/3 from the abdomen lenght. The abdomen represents 6/3 from the body lenght, and the prothorax and head lenght reported to the body lenght represents 2/8.
