Oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera: Tortricidae) is a cosmopolitan pests of fruit trees in temperate regions. Control of G. molesta is challenging because larvae feed in concealed locations and have evolved resistance to many pesticides. We compared three commercially available species of Trichogramma for efficacy against G. molesta in the laboratory assays and tested releases of the promising species in a pear orchard.

实验室和田间研究支持使用赤眼蜂（Drichogramma dendrolimi）（膜翅目：Trichogrammatidae）增强对东方果蛾（Grapholita molesta，鳞翅目：Tortricidae）的生物防治。

东方果蛾Grapholita molesta（Busck）（鳞翅目：Tortricidae）是温带地区果树的世界性害虫。控制G.食心虫是具有挑战性的隐蔽位置，因为幼虫饲料，已经发展到许多农药抗性。我们在实验室测定中比较了三种可商购的赤眼蜂属物种对G. molesta的功效，并在梨果园中测试了有前途的物种的释放。
