本研究的目的是确定在草莓（Fragaria x ananassa）中防治中央斑杜鹃（Duponchelia fovealis）的理想放放量。试验在温室中进行，在草莓品种‘Oso Grande’上感染100个分布在每株植株叶表面的中央斑叶蚜卵。每卵分别释放1、2、4、8、16、32、64和128只雌拟寄生虫。赤眼蜂卵的寄生率最高，不同种类赤眼蜂的寄生率没有差异，在每颗卵4和8只寄生蜂的密度时观察到，这被认为是野外释放的理想选择。
The objective of this work was to determine the ideal number for field release of Trichogramma galloi and T. pretiosum for controlling Duponchelia fovealis (Lepidoptera: Crambidae) in strawberry (Fragaria x ananassa). The experiment was carried out in a greenhouse, where the strawberry cultivar 'Oso Grande' was infected with 100 eggs of D. fovealis distributed on the leaf surface area of each plant. A total of 1, 2, 4, 8, 16, 32, 64, and 128 female parasitoids were released per egg of D. fovealis. The greatest level of egg parasitism, with no differences for the species of Trichogramma, was observed at the densities of four and eight parasitoids per egg of D. fovealis, considered ideal for field release.
