Abstract(s)
The recent capture at the island of São Miguel-Azores of a local type of Trichogramma cordubensis Vargas & Cabello (Hym., Trichogrammatidae) gave rise to the question of its epigenetic characterization, according to parameters indentical to those of the continental type. This characterization was carried out with the objective of recognizing its ability to be used as a biological control agents against agricultural pests in this region. It was verified, for this local type, that, in similarity with the continental type, the maximum of its parasitic capacity occurs in the first day after emergence. This seems to indicate that this insect should be introduced in the inundative release fields before its emergence. The local type of T. cordubensis diverged significantly from the continental type in its longevity.
