Problems solved by technology

At present, in my country's silkworm seed production technology, the efficiency of silkworm mating rate is not high, and the quality of fertilization is not high, resulting in low economic efficiency of industrialization
Good progress has been made in insect pest control using sex attractants, such as using Z / E-9-ene dodecyl alcohol acetate to control sugarcane yellow borer and jujube armyworm; using Z / E-9-ene tetradecyl Alcohol acetate is used to control tea leaf tortrix and orange leaf tortrix; use Z / E-9-ene hexadecanyl alcohol acetate to control rice borer, etc., but there is no related technical method in the use of sexual attractants to promote silkworm mating to report

Embodiment 1

[0018] A method of utilizing a sexual attractant to promote the mating of Yisan to the original silkworm, comprising the steps of:

[0019] Step (1), catching the moths and selecting the moths, choosing to be photosensitive at 5 o'clock in the morning, after photosensitive, the male moths should be grabbed in time, and the female moths that have been crossed should be eliminated. To catch moths, put 150 female moths on each foil and send them to the mating room. In order to ensure the quality of silkworm seeds, seedling tail moths must be strictly eliminated, and bad moths must be strictly selected in each process of catching moths, pairing, folding, casting and patrolling. disuse;

[0020] Step (2), prepare the sexual attractant, select Z / E-9-enedodecyl acetate as the sexual attractant, and use n-hexane as a solvent to prepare a sexual attractant solution with a concentration of 0.001‰ for use;

[0021] In step (3), the mating pair is selected to be mated 4 hours after eclos...

Embodiment 2

[0027] A method of utilizing a sexual attractant to promote the mating of Yisan to the original silkworm, comprising the steps of:

[0028] Step (1), catching the moths and selecting the moths, choosing to be photosensitive at 5 o'clock in the morning, after photosensitive, the male moths should be grabbed in time, and the female moths that have been crossed should be eliminated. To catch moths, put 160 female moths on each foil and send them to the mating room. In order to ensure the quality of silkworm seeds, seedling tail moths must be strictly eliminated, and bad moths must be strictly selected in each process of moth catching, arranging, folding, casting and patrolling. disuse;

[0029] Step (2), prepare the sexual attractant, select Z / E-9-enetetradecyl acetate as the sexual attractant, and use n-hexane as a solvent to prepare a sexual attractant solution with a concentration of 0.002‰ for use;

[0030] In step (3), the mating pair is selected to be mated 4 hours after e...

Embodiment 3

[0036] A method of utilizing a sexual attractant to promote the mating of Yisan to the original silkworm, comprising the steps of:

[0037] Step (1), catching the moths and selecting the moths, choosing to be photosensitive at 4:30 in the morning. After photosensitive, the male moths should be grabbed in time, and the female moths that had been crossed should be eliminated. To catch moths, put 170 female moths on each foil and send them to the mating room. In order to ensure the quality of silkworm seeds, seedling tail moths must be strictly eliminated. moth culling;

[0038] Step (2), prepare the sexual attractant, select Z / E-9-enehexadecyl acetate as the sexual attractant, and use n-hexane as a solvent to prepare a sexual attractant solution with a concentration of 0.003‰ for use;

[0039] In step (3), the mating pair is selected to be mated 3.5 hours after eclosion, and 3 mL / m of the sexual attractant solution obtained in step (2) is sprayed into the female moth foil. 3 ,...

Abstract

The invention relates to a method for promoting easy-depairing parent silkworm mating with sex attractants and belongs to the technical field of silkworm egg breeding. The method comprises a mating pairing step. According to mating pairing, 2-5 mL / m<3> sex attractant solutions with the concentration of 0.001%o-0.005%o is sprayed into a female silkworm frame, then male silkworms with the number 5%-10% larger than the number of female silkworms are added for mating, mating time is 2 h-6 h, mating chamber temperature is kept at 75 degrees Fahrenheit, and dry-wet difference is 3-4 degrees Fahrenheit. According to the silkworm egg breeding method, mating of female silkworms and male silkworms is carried out, silkworm mating rate is improved to 98.6%, fertility rate reaches 95.5%, and silkworm large-scale industrialization development can be promoted.

Description

technical field [0001] The invention belongs to the technical field of silkworm seed breeding, and particularly relates to a method for promoting the mating of Yisan to the original silkworm by utilizing a sexual attractant. Background technique [0002] Silkworm originated in China with a history of more than 5,000 years. As the biological basis of silk industry and an important model organism, it has made important contributions to the development of society and science, and has outstanding research achievements. In the early 1970s, my country became the world's largest silk producer. The annual export of silk earned nearly 4 billion US dollars, which made important contributions to the development of my country's national economy. The technology of silkworm seed production played an important role in promoting the development of my country's silkworm industry. effect. At present, the efficiency of silkworm mating rate and fertilization quality in silkworm seed production ...
