Artificial diet for Lepidopterous young larvae, preparation method for artificial diet and application of artificial diet

The invention provides an artificial diet for Lepidopterous young larvae. The artificial diet for the Lepidopterous young larvae is prepared from the following raw materials in percentage by weight: 2.0 to 3.0 percent of soybean cake meal, 7.0 to 10.0 percent of corn flour, 2.0 to 3.0 percent of Saccharomyces cerevisiae Hansen, 7.0 to 10.0 percent of tomato sauce, 0.8 to 1.2 percent of sucrose, 1.2 to 1.4 percent of agar, 0.2 to 0.5 percent of sorbic acid, 0.05 to 0.1 percent of vitamin B complex, 0.2 to 0.4 percent of ascorbic acid, 0.1 to 0.2 percent of ethyl p-hydroxybenzoate, 0.2 to 0.4 percent of propionic acid and 71.0 to 77.0 percent of water. The invention also provides a method for preparing the artificial diet and application of the artificial diet. The artificial diet is low in manufacturing cost, easy to operate and high in practicability; and by the artificial diet and the raising method for raising the Lepidopterous young larvae, the survival rate of the larvae is high, the workload is low, and
