dc.description.abstractThe egg parasites of the genus Trichogramma (Hym., Trichogrammatidae), are important Biological auxiliaries used in over 20 million acres, in more the 20 countries around the word, for the control of agricultural pest namely lepidopterans (Trichogramma News, 1988), having Portugal a contribution of over 400 acres in 1990. The obtainment of the necessary amounts of Trichogramma with the desired quality, passes fundamentally by the knowledge of its biology and etology as well as by the usage of efficient production techniques. In this time, the influence of the photoperiod’s over the egg laying rhythm and emergence of three Trichogramma species. Trichogramma biesi VOEGELÉ, T. maidis PINTUREAU & VOEGELÉ and T. embryophagum HARTIG, accepted as representatives for three vegetables extracts, respectively of low medium and high altitudes, where studied.por
