At present, the application of Trichogramma to control agricultural and forestry pests has become one of the important means of biological control, and widely used in the production of agriculture and forestry.Because of the increasing application area, the demand for Trichogramma is also increasing rapidly with Japan, the current production On the use of natural eggs (tussah eggs, castor silkworm eggs, eggs, etc.) as the host of the indigenous method of bee breeding has not adapted to the needs of production development.
