Provided is a
trichogramma japonicum high-efficiency
reproduction method. The method comprises: collecting eggs of rice moths, and sticking the eggs on paper boards to make egg cards; putting
trichogramma japonicum species and eggs of rice moths in a
darkroom in proportion of 1:10 to 1:4, adjusting bee species emergence parasitic environment temperature to 23 to 25 DEG C, adjusting
humidity to 70% to 80%; after 90% of the egg cards have parasitic bee species, adding fresh
rice moth egg cards according to 1:6-10 of proportion of the bee species and the egg cards again, properly increasing temperature of the
darkroom to 25 to 28 DEG C, and maintaining the
humidity; after more than 90% of the egg cards have parasitic bee species, adding fresh
rice moth egg cards according to 1:3-7 of proportion of the bee species and the egg cards for the third time, the egg cards this time being sprayed with
cane sugar nutrient solution, the bee species continuing to reproduce. The method can realize using the
trichogramma japonicum to prevent rice leaf folders and striped rice borers, and
pesticide dose is greatly reduced. The method promotes
agriculture to develop towards green, organic, and
ecological agriculture.
