Abstract

The invention provides a method for preserving silkworm eggs, and specifically relates to the technical field of insect breeding. The present invention comprises the following steps: a. silkworm egg protection: silkworm eggs are placed on different silkworm plaques according to the age of eggs and eggs of non-age age, and protected for 55-65 hours; b. silkworm egg disinfection: use a temperature of 12 ‑20°C disinfectant solution spraying or dipping; c. Silkworm eggs are activated to obtain activated eggs: soak in activating solution at a temperature of 6‑12°C for 12‑28 minutes; d. Activated eggs are protected and stored in a cold storage: use temperature After spraying with a protective solution at 1‑5°C and drying it, store it in a refrigerator at ‑6 to ‑12°C. The silkworm eggs of the invention have long storage time, uniform hatching and high hatching rate in one day. The method of the invention is simple to operate, flexible and controllable, and easy to industrialize.

Description

【Technical field】 [0001] The invention relates to the technical field of insect breeding, in particular to a method for preserving silkworm eggs. 【Background technique】 [0002] Silkworms are the larvae of silkworm moths, the main source of silk raw materials, and occupy an important position in human economic life and cultural history. Raising silkworms to get silk is a great invention of the working people in ancient my country. Nowadays, the silkworm industry is also developing continuously, the area of ​​mulberry gardens is expanding, and the number of silkworms is increasing. [0003] In order to adapt to the changes in the natural environment, after a long evolution, silkworms have differentiated into two constitutions: they can produce older eggs or diapause eggs in a harsh environment, and produce non-aged eggs or non-diapause eggs in a mild environment. feature. Non-year-old eggs cannot be stored for a long time after they are produced, and need to be hatched in a...
