Description
Summary:Prout (Lepidoptera: Geometridae) is an important lepidopteran defoliator of eucalyptus. eggs were collected naturally in a commercial plantation of W. Hill (Myrtaceae) in Três Lagoas, Mato Grosso do Sul, Brazil. After nine days, the natural emergence of  Riley (Hymenoptera: Trichogrammatidae) occurred from eggs. Parasitism was evaluated under laboratory and field conditions, this being the first record for eucalyptus in Brazil. Based on the biological characteristics evaluated in the laboratory, eggs are suitable for reproduction. The obtained percentage parasitism, particularly when 72,000 adult females of per hectare were employed, provide valuable insights regarding the potential of as an effective biological control agent against in eucalyptus plantations.
