Five flavor berry; Schisandra chinensis Baill is used in traditional Chinese medicine, it is believed to astringe lung and nourish the kidneys, restrain the essence and stop diarrhea-astringent kidneys, calm the spirit by tonification of heart and kidney, Generate body fluids and alleviate thirst. The development of biological control against the major pest on five flavor berry is of great interest. Yellow tea thrip; Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) is anthophilous pests of many crops worldwide including five flavor berry.

In this work, a treatment of Amblyseius swirskii Athias-Henriot was applied to two types of five flavor berry fields infested by S. dorsalis. Even though our tests found significant differences between the two culturing method, the treatment of biological control agents decreased or a little increased the fruit damage, which was comparable to the chemical insecticide treatment. In the sod culture experiment, thrip population was significantly low and increased at a lower rate than in the nonwoven type mulching. So the use of A. swirskii as IPM program and sod culture reduce pesticide usage.
