[Dispersion capacity of Trichogramma pretiosum in propped up tomato]
Pesquisa Agropecuária Brasileira 40 (6), 613-616
Abstract: The dispersion capacity of Trichogramma pretiosum Riley was studied on Anagasta kuehniella (Zeller) eggs, in tomato field in different phenological stages and systems of conduction of the plants. The dispersion of T. pretiosum, 24 hours after the liberation, attained 7.37 to 7.94 m. The dispersion area was 120.20 to 138.72 m². Parasitism varies from 53.1% to 87.3% and it is significant according to the phenological stage of the crop. The parasitoids liberation for the control of Tuta absoluta (Meyrick) should be done in 75 points per hectare.
