The invention discloses a biomedical engineering material and a preparation method thereof, in particular to a three-dimensional tissue repair material and a preparation method thereof, which belong to the technical field of biomedical materials. It uses natural tussah silk as raw material. After the tussah silk fibroin is dissolved, the electrostatic spinning method is used to obtain a three-dimensional non-woven network structure composed of tussah silk fibroin fibers. The fiber diameter is 50nm-20μm, and the pores between the fibers are 1-500μm. , the thickness of non-woven net is 50nm~20mm; the molecular weight of tussah silk fibroin is 10×104~20×105D. This biomedical engineering material has the characteristics of non-toxic and harmless, good biocompatibility, and excellent cell adhesion and growth performance. It is rich in raw materials and low in cost. It is expected to replace high-cost biomedical materials such as collagen for artificial skin, Repair materials such as tendon, cartilage, and dura mater, especially tissue cell induction materials.

The invention discloses a method for artificial propagation of the black-crowned wasp, which comprises the following steps: (a) selecting an alternative host, (b) collecting and screening the pupae of the moth moth in the field, (c) cultivating bee species, (d) Information material extraction, (e) tussah silkworm chrysalis treatment, (f) inoculation with bees, (g) cultivation and development. The present invention obtains the pupal surface extract by soaking the unparasitic pupa in alcohol, and then sprays it on the tussah chrysalis by the method of artificial spraying, induces the parasitism of the black rod gnat, and improves the parasitic rate; adopts indoor large-scale propagation of the black rod gnat, for Forest biological control of Lepidopteran pests such as American white moth and poplar moth provides practical technical means.

The present invention discloses composing components of an antheraea pernyi ovary cell culture medium, a preparation method of the antheraea pernyi ovary cell culture medium, and an application of the antheraea pernyi ovary cell culture medium in antheraea pernyi ovary cell culture. According to the present invention, a prepared amino acid and sugar mixing storage solution (MLM-AAS), an inorganicsalt storage solution (MLM-Salt), a vitamin storage solution (MLM-Vit), bovine serum albumin, fetuin and the like are prepared according to a certain ratio, and the pH value is adjusted to 6.2-6.4 toobtain a MLM-45 culture medium, wherein the prepared MLM-45 culture medium is added with fetal bovine serum and a penicillin and streptomycin mixing solution according to a certain volume ratio before the prepared MLM-45 culture medium is used, the volume ratio of the fetal bovine serum is 20%, and the volume ratio of the penicillin and streptomycin mixing solution is 1%. With a plurality of experiments, the following in vitro cell growth conditions are determined that: the culture temperature is 26-28 DEG C, the pH value is 6.2-6.4, and the osmotic pressure is 315-350 mOsm / kg. With the present invention, technical services are provided for researches in antheraea pernyi biology, antheraea pernyi pathogenic microorganism and related fields.

A preparation method of antheraea pernyi food is characterized by comprising steps as follows: material selection: fresh antheraea pernyi or fresh and timely frozen antheraea pernyi is selected; removal of scaly hair: a part of scaly hair on the body surface of antheraea pernyi is sieved out with a sieve with the mesh diameter of 0.5-1 cm, and the antheraea pernyi is left for standby; drying: the selected antheraea pernyi is put in a microwave drying machine, and the antheraea pernyi is completely dried through microwave drying, and the obtained antheraea pernyi food with an original flavor can be obtained; or the selected fresh antheraea pernyi can be subjected to microwave drying and cooked, the cooked antheraea pernyi is immersed in a spiced, spicy, sweet and spicy or cumin seasoning juice formed by mixing seasonings with a proper amount of water, soaked, pickled and subjected to microwave drying, and the flavored antheraea pernyi food is obtained; the antheraea pernyi food is cooled to the room temperature and subjected to vacuum packaging, and an antioxidant desiccant is put into each package or nitrogen-filling packaging is performed. The antheraea pernyi does not shrivel after being dried, the appearance is plump, and the antheraea pernyi food is easy to eat and tastes crisp. The antheraea pernyi food is cooled to the room temperature and then subjected to vacuum packaging or nitrogen-filling packaging, can be eaten after the bag is opened, is convenient to store and transport and is nutritional food for people at home, in travel or in leisure time.

The invention discloses an artificial breeding method of Anastatus orientalis and an application in forest pest control. Ova of Antheraea pernyi are selected as alternative hosts for Anastatus orientalis, and suitable breeding conditions are screened, so that the parasitic capability of Anastatus orientalis is significantly improved. Lycorma delicatula is controlled by means of Anastatus orientalis, and the parasitic effect of Anastatus orientalis on Lycorma delicatula ova is good.
