Embodiment 1

[0012] Example 1: Preparation of medicinal solution: each silkworm egg (10g ant silkworm) was prepared with 1g of jinlusamsin to make 2.5kg medicinal solution, and the 1st to 2nd instar silkworms were reared according to the conventional silkworm breeding method, and the formulated medicinal solution The liquid was evenly sprayed on the mulberry leaves with a sprayer. After the medicinal liquid was slightly dried, the larvae began to feed continuously for 48 hours, four times a day. The rearing temperature during the leaves was maintained at 26.0°C.

Embodiment 2

[0013] Example 2: Preparation of medicinal solution: each silkworm egg (10g ant silkworm) was prepared with 1g of jinlusamsin to make 2.5kg medicinal solution, and the 1st to 3rd instar silkworms were raised according to the conventional silkworm rearing method, and the formulated medicinal solution The liquid was evenly sprayed on the mulberry leaves with a sprayer. After the medicinal liquid was slightly dried, the 4th instar larvae began to feed continuously for 48 hours, four times a day. The rearing temperature during the leaves was maintained at 26.0°C.

[0014] After comparative testing, the following data are obtained:

[0015] 1) An average of 3.22kg of three-sleeping silkworm cocoons per hundred catties of mulberry leaves, and 2.81kg of four-sleeping silkworm cocoons;

[0016] 2) The relaxation rate of Sanmian silkworm was 76.85%, and that of Simian silkworm was 66.84%, an increase of 10 percentage points;

[0017] 3) The fineness of Sanmian silk is 1.25-1.63D, and...

Abstract

The invention discloses an energy-saving and high-yield silkworm breeding method. The energy-saving and high-yield silkworm breeding method comprises the following steps of: breeding 1-2-year silkworms according to a conventional silkworm breeding way; preparing a juvenile hormone resistant solution when 3-year silkworms are firstly fed; and uniformly spraying the solution on the surfaces of mulberry leaves to feed the silkworms to ensure that a common tetramolters become trimolters; by using the silkworm breeding method, the breeding time is shortened and the leaf feeding quantity is reduced; the manpower and the feed cost are reduced; the cocoon silk quality and the fineness are improved; and the 3-year inductivity is up to 97%, the cocoon quality is approximately equal to the qualities of other five varieties, the silk yield is relatively low, but the fineness of the trimolter cocoon silk induced by 3-year silkworms in six varieties is smallest and is 1.079D, and the finenesses of cocoon silks of other five varieties range from 1.606D to 1.755D.

Description

technical field [0001] The invention relates to a method for raising silkworms, in particular to an energy-saving and high-yield method for raising silkworms. Background technique [0002] Mulberry silkworm (Bombyx mori) is an insect domesticated from the ancient wild silkworms moved indoors, and feeds on mulberry leaves. Silkworms eat leaves and grow to form cocoons on mature silkworms. During the whole growth and development process, it has its own regularity. The silkworm and the external environment are a unified and inseparable whole. The growth and development of silkworms are directly related to environmental conditions such as mulberry leaves, temperature, humidity, and air. The general silkworm breeding cycle is 25 to 30 days, and the fifth-instar silkworm spins silk and cocoons. Silkworms breed with eggs, and new organisms are formed inside the eggs. The larvae that form inside the egg hatch by biting the eggshell. The larvae that have just emerged from the...
