Embodiment 1

[0020] This embodiment includes the following steps:

[0021] (1) Spawning room preparation: Avoid direct sunlight, no sound, no electromagnetic waves, no toxic and harmful gases and other environmental pollution in the spawning room; the temperature is controlled at 20°C, and the relative humidity is controlled at 88%; and spray disinfection with 3wt% bleach solution Twice; an ovipositor is provided indoors; the ovipositor is provided with an egg-laying grid; the egg-laying grid of the ovipositor is wrapped with blue screen cloth;

[0022] (2) Oviposition: Place 500 mated female moths in 250 ovipositing cells of the ovipositor; one day later, the female moths start to lay eggs; moth dies naturally;

[0023] (3) Resting: keep the temperature at 20°C and the relative humidity at 88%, put 101,000 silkworm eggs in place for 12 days, so that the embryos in the egg shells will completely become tangible ant silkworm embryos;

[0024] (4) Divide into storage: put 101,000 silkworm ...

Embodiment 2

[0028] This embodiment includes the following steps:

[0029] (1) Spawning room preparation: the temperature is controlled at 21°C, and the relative humidity is controlled at 87%; and sterilized twice with 3wt% bleach solution; the spawning grid of the ovipositor is wrapped with green gauze; the rest is the same as in Example 1;

[0030] (2) Oviposition: Place 400 female moths that have just mated in 200 oviposition cells of the ovipositor; one day later, the female moths begin to lay eggs; moth dies naturally;

[0031] (3) Resting: keep the temperature at 21°C and the relative humidity at 87%, put 90,000 silkworm eggs in place for 15 days, so that the embryos in the egg shells will completely become tangible ant silkworm embryos;

[0032] (4) Divide into storage: 90,000 silkworm eggs after resting are put into 210 silkworm egg bags according to the requirements of variety, quality, time and quantity, and sent to the silkworm egg storage; the silkworm egg storage is used for ...

Abstract

The invention provides a method for protecting Nanling giant silkworm eggs. The method includes the following steps: (1) preparing a spawning chamber; (2) placing mating female moths in a spawning case of a spawning device to spawn; (3) standing spawned silkworm eggs in situ for 10-15 days; (4) dispersing into warehouses; and (5) regulating temperature and moisture and taking care. According to the method for protecting Nanling giant silkworm eggs, hatching rate of the Nanling giant silkworm eggs is above 90%, energy consumption is low, and batch breeding and industrialization development of giant silkworms are achieved.

Description

technical field [0001] The invention relates to a method for protecting the eggs of the cerevisiae cerevisiae, in particular to a method for protecting the eggs of the ceremonium cerevisiae in Nanling. Background technique [0002] The celestial silkworm is a worldwide endangered creature and a rare species of wild silkworm in my country. It is an agricultural biological resource under national key protection promulgated by the Ministry of Agriculture. [0003] As early as the Tang Taizong period, my country had records of green cocoons (celestial silkworms), and it was the first country in the world to make written records of silkworms. In the early 1930s, Gaixian County, Liaoning Province carried out research on celestial silkworms. In 1958, when harvesting tussah cocoons in Heilongjiang Province, a small amount of celestial silkworm cocoons were found. However, it was not until 1980 when the foreign exchanges realized the value of the silkworm. In the early 1990s, the H...
