The invention discloses a synergistic processing method for breeding trichogramma chilonis by using an oak silkworm egg, and trichogramma chilonis is bred by using the oak silkworm egg under a manual controlled condition. The method comprises the following steps of soaking the surface of a fresh oak silkworm disemboweled egg by a preprocessed solution; taking out and airing the oak silkworm disemboweled egg to be used as a progeny egg for receiving the trichogramma chilonis; after the eclosion of the trichogramma chilonis from a parental egg, placing the parental egg and the progeny egg with the preprocessed surface together in a dark environment; after a parasitism link, removing the parental egg and the trichogramma chilonis; retaining the progeny egg, wherein the growth and eclosion of the trichogramma chilonis are completed under conditions that the wavelength of a blue light is 475-495 nm and the illumination intensity is 500-1000 lux. In large-scale reproduction, various development indexes of the trichogramma chilonis are better; the stability is stronger. Comparing the method with the traditional method, the parasitism rate can be increased by 4-26 percentage points; the trichogramma chilonis number of a single egg is moderate; the uniformity degree of samples in a sampling room is better; the eclosion rate can be increased by 0.2-4 percentage points; the parasitism rate is increased and maintained at a higher level; the trichogramma chilonis left rate is reduced by 1-3 percentage points; the uniformity degree of samples in the sampling room is better.
