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

Method for producing offspring of wild silkworm
Technical field
The present invention relates to the cultural method of a kind of insect, the producing method for seed of especially a kind of giant silkworm.
Background technology
Giant silkworm belongs to rare Lepidoptera Saturniidae spun silk insect, univoltine, and complete metamorphosis, larva 4 slept for five ages staple food robur leaf.The silk that giant silkworm told is natural fruit green, and the title of " king in the silk ", " diamond fiber " is arranged.The appearance of giant silkworm is apart from the history of existing more than 1300 year of the present.Giant silkworm mainly is distributed in ground such as Chinese northeast, Hunan, Guangxi, also sees Japan and India.In the world, Japan is to the research of giant silkworm and drops into more country.The Heilungkiang of China is in the eighties giant silkworm that also begins one's study in last century.But the problem of still unresolved so far batch artificial seed and breeding.The beginning of the nineties in last century, the scientific research personnel that Hunan China is economized is after wild giant silkworm is found on this province domestic Nan Ling mountain range, in project verification research in 1991, the painstaking efforts through the more than ten years were obtaining a series of breakthrough and progress aspect artificial seed, breeding and the raising of giant silkworm finally.
Summary of the invention
The technical problem to be solved in the present invention is, at the defective of prior art, proposes a kind of method for producing offspring of wild silkworm, and this method is by artificial propagation and breeding technology, and the batch that can realize giant silkworm is cultured and industrial scale melts.
Technical solution of the present invention is that described method for producing offspring of wild silkworm is to be following step:
(1), moves silkworm.With wild giant silkworm, transfer to conventional giant silkworm rearing method raising in the following massif oakery of height above sea level 500m;
(2), select ground.Select the southeast to the oakery on hillside as production of hybrid seeds field;
(3), seed selection.Select even, anosis, the no worm of cocoon layer, even, anosis, the no worm of female cocoon and the cocoon layer of its body weight in 8~14g scope, the male cocoon of its body weight in 7~13g scope is as kind of a cocoon, and selected female cocoon is 1:1~2 with the quantity ratio of male cocoon;
(4), classification.With selected female, the male two all cocoons of step (3) by the date class mark of cocooing, pupate so that in time grasp the emergence time;
(5), mating.The kind cocoon for the treatment of step (4) begins to sprout wings, and by the wing of catching female moth female moth is placed on the robur of above-mentioned production of hybrid seeds field.So that allow female moth attract male moth that it is discharged male pheromones.Allow male moth and the free mating of above-mentioned female moth.Treat that mating finishes, put into the bag of laying eggs going the female moth of mating;
(6), lay eggs.Treating that female moth lays eggs in the above-mentioned bag of laying eggs finishes, and takes out kind of an ovum from the bag of laying eggs, and will plant ovum then and insert the kind ooecium of indoor temperature in 26~28 ℃ of scopes and preserve, and the production of hybrid seeds finishes.
The invention has the beneficial effects as follows, carry out the artificial propagation of giant silkworm according to above-mentioned method for producing offspring of wild silkworm, solve giant silkworm and cultured the field difficult problem of artificial seed and breeding in batches not yet so far, realize in enormous quantities, the high mating rate of giant silkworm, the high spawning rate production of hybrid seeds, promoted the extensive industrialization development that giant silkworm is cultured.
Embodiment:
Embodiment 1,
(1), moves silkworm.Economize the wild giant silkworm in zone about Nan Ling mountain range height above sea level 1400m with originating in Hunan China, transfer to conventional giant silkworm rearing method raising in the following massif oakery of height above sea level 500m;
(2), select ground.Select on the spot the southeast to the oakery on hillside as production of hybrid seeds field;
(3), seed selection.Select even, anosis, the no worm of cocoon layer, even, anosis, the no worm of female cocoon and the cocoon layer of body weight 8g, the male cocoon of body weight 7g is as kind of a cocoon, and selected female cocoon and male cocoon respectively are 1000;
(4), classification.With selected female, the male two all cocoons of step (3) by the date class mark of cocooing, pupate so that in time grasp the emergence time;
(5), mating.The kind cocoon for the treatment of step (4) begins to sprout wings, and by the wing of catching female moth female moth is placed on the robur of above-mentioned production of hybrid seeds field.So that allow female moth attract male moth that it is discharged male pheromones.Allow male moth and the free mating of above-mentioned female moth.Treat that mating finishes, put into the bag of laying eggs going the female moth of mating;
(6), lay eggs.Treating that female moth lays eggs in the above-mentioned bag of laying eggs finishes, and takes out kind of an ovum from the bag of laying eggs, and will planting ovum then, to insert indoor temperature be 26 ℃ kind ooecium, and the production of hybrid seeds is promptly accused and finished.
In the present embodiment, the mating rate of giant silkworm reaches 95%, fertilization rate reached 92%, and single moth ovum quantum of output is 180.
Embodiment 2,
Step (1)~(2) are with embodiment 1;
(3), seed selection.Select even, anosis, the no worm of cocoon layer, even, anosis, the no worm of female cocoon and the cocoon layer of body weight 14g, the male cocoon of body weight 13g is as kind of a cocoon, and selected female cocoon is 50000, and selected male cocoon is 100000;
