Embodiment 1

[0013] (1), moving silkworms. The wild celestial silkworm native to the Nanling Mountains in Hunan Province, China, at an altitude of about 1400m, was transferred to the hill oak forest below 500m above sea level for conventional artificial breeding of celestial silkworms;

[0014] (2), choose a place. Select the oak forest on the southeast slope as the seed production field;

[0015] (3), selection. Select female cocoons with uniform cocoon layer, disease-free, insect-free, body weight 8g and male cocoons with uniform cocoon layer, disease-free, insect-free, body weight 7g as seed cocoons, and the selected female cocoons and male cocoons are each 1000;

[0016] (4), classification. The selected female and male cocoons of step (3) are marked according to the classification of cocooning and pupation dates so as to grasp the eclosion time in time;

[0017] (5), mating. The seed cocoon of step (4) begins to emerge, and the female moth is placed on the oak tree of the above-m...

Embodiment 2

[0021] Steps (1)~(2) are with embodiment 1;

[0022] (3), selection. Select female cocoons with uniform cocoon layer, disease-free, insect-free, body weight 14g and male cocoons with uniform cocoon layer, disease-free, insect-free, and body weight 13g as seed cocoons. The selected female cocoons are 50,000, and the selected male cocoons are 100,000 Only;

[0023] Steps (4)~(5) are the same as in Example 1;

[0024] (6), spawning. Treat that the female moth finishes laying eggs in the above-mentioned egg-laying bag, take out the seed eggs from the egg-laying bag, then put the seed eggs into the seed egg chamber that the indoor temperature is 28°C, and the seed production is completed.

[0025] In this embodiment, the mating rate of the silkworm reaches 98%, the fertilization rate reaches 95%, and the output of single moth eggs is 440.

Abstract

The invention discloses an egg production method for wild silkworms, which comprises the following steps: (1) the wild silkworms are moved to oak forests with the elevation below 500m for raising; (2) an oak forest, the southeast of which faces to a hillside, is selected as an egg production farm; (3) female cocoons and male cocoons with uniform, disease-free and pest-free cocoon shells are selected as cocoons for egg production; (4) the cocoons for egg production are sorted and marked; (5) after the cocoons for egg production are eclosion, female moths are placed on oak trees to be copulated with male moths, and the copulated female moths are placed into an egg laying bag; and (6) after the egg laying is finished, eggs are placed into an egg chamber with room temperature of between 26 and 28 DEG C for preservation. The artificial propagation of the wild silkworms according to the method solves the problem that the mass artificial egg production and wild silkworm propagation is not be performed, realizes the egg production in large batch, high mating rate and high egg-laying rate of the wild silkworms, and promotes the industrialized mass development of wild silkworm breeding.

Description

technical field [0001] The invention relates to a breeding method for insects, in particular to a seed production method for celestial silkworms. Background technique [0002] Celestia cerevisiae, a rare silkworm belonging to the family Lepidoptera, Saccharidae, monomorphic, complete metamorphosis, larvae in four to five instars, staple food on oak leaves. The silk spun by the silkworm is natural fruit green, known as "the king of silk" and "diamond fiber". The appearance of silkworms has a history of more than 1300 years. The celestial silkworm is mainly distributed in Northeast China, Hunan, Guangxi and other places, and is also found in Japan and India. Internationally, Japan is a country that researches and invests more in the silkworm. China's Heilongjiang also began to study celestial silkworms in the 1980s. But the problem of artificial seed production and propagation in batches has not yet been solved. In the early 1990s, researchers in Hunan Province, China, di...
