Abstract
Summary The biometrical comparison of Trichogramma maidis, T. nubilale and of two T. sp. from Alsace, has been effected, with the males then the females, with the help of 25 measured characters on antenna, phragma, forewing, hinder leg and genitalia. With the males, a multivariate analysis which considers the 19 discriminating characters, allows the complete separation of species; except T. maidis from one alsatian species, crossing each other very partially. The genitalia and antennae (sexual characters) are the data which allow to recognize best the species. On the other hand, with the females, a multivariate analysis which considers the 8 discriminating characters, doesn't allow a good separation of species.
