Silkworm egg combination suitable for producing medicinal bombyx batryticatus

Abstract

The invention provides a silkworm egg combination suitable for producing medicinal bombyx batryticatus. The silkworm egg combination comprises the following varieties of silkworm eggs: Baichun and Fangxiu, Chuanshan and Shushui, Jinyuan and Lingzhou, and Liangguang No.2. The invention also provides a medicinal bombyx batryticatus breeding method which comprises the following steps: alternately breeding Baichun and Fangxiu or / and Chuanshan and shushui in spring and late autumn, and selecting Jinyuan and Lingzhou or Liangguang No. 2 in summer and early autumn, wherein the breeding temperature is26+ / -2 DEG C, and the humidity is 75+ / -5% RH; and enabling the silkworm eggs to be satiated fully. The silkworm egg combination has the advantages of high operability, cost saving, relatively high yield of produced bombyx batryticatus, relatively good appearance and good quality, and the method is suitable for artificially large-scale breeding of bombyx batryticatus.

Description

technical field [0001] The invention relates to a combination of silkworm eggs produced by multi-season medicinal silkworms. Background technique [0002] Bombyx mori is derived from the dead body of Bombyx mori Linnaeus 4-5 instar larvae infected with Beauveria assiana (Bals.) Vuillant. , convulsions, epilepsy, convulsions in children, tetanus and other diseases. With the in-depth research on the pharmacological components and functions of the silkworm and the continuous development of related new products, the application of the silkworm in the medicinal field will become more and more extensive. In the actual production process of Bombyx mori, different silkworm species show different infection rates to Beauveria bassiana and other miscellaneous bacteria, resulting in different growth cycles of Bombyx mori, unstable yield, and ultimately affecting the quality of Bombyx mori. [0003] Since ancient times, silkworm eggs are mainly derived from silkworm species. Silkworms ...

AI Technical Summary

Problems solved by technology

Different silkworm species have different sensitivities to Beauveria bassiana, resulting in different growth and development after inoculation, which ultimately affects the yield and quality of silkworms

[0004] Yang Qiong et al., Research on the Artificial Culture of Medicinal Bombyx larvae [J], Guangdong Sericulture 44(4): 34-38 discloses the artificial culture method of Bombyx botany, strain screening, optimal inoculation dose, suitable silkworm Among them, the silkworm eggs used are: polymorphic varieties: Fang 4, Jiaqiu; Chinese secondary varieties: Feng 9, Chun 5, Yueyin 3, Taihuang 1; Japanese secondary varieties: Yan 7, Xiang A, Kinshu shape, 231 Xia; quaternary hybrids: 9 · Fu × 7 · Xiang, 7 · Xiang × 9 · Fu; ​​when the inoculation concentration is controlled at 10 5 a / mL~10 6 When each / mL, more than 90% of the morbidity and death are basically reached within 2 days, the silkworm body is small, and the yield and quality of the dead silkworm cannot be guaranteed.
