Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with example to the present invention into
Row is further described.It should be appreciated that specific example described herein is not used to limit this only to explain the present invention
Invention.
Accelerate for Development of China's Urbanization, rural laborer pours in city, as this seasonal use of silkworm egg reproduction
Work supply is becoming tight, and the obvious aging of structure of personnel causes male and female separation cost to rise steadily.The present invention reduces male silkworm raising, in hero
Silkworm ratio is selected and remain, and middle system's kind is centered on to hand over kind 70%, Japanese kind the 75% of kind can be to handing over
The heart；Autosexing race takes a point feeding technology, implements female silkworm intensive culture after male and female silkworm separates.
Application principle of the invention is explained in detail below with reference to example.
The present invention raises ratio, isolating female from male culture by carrying out male silkworm, and it is excellent in silkworm egg reproduction to give full play to autosexing race
Gesture improves breeding coefficient, improves qualification rate, improves hybrid rate, reduces silkworm egg production cost, expands the economic effect of silkworm egg reproduction
Benefit provides high-quality silkworm egg for Sericultural production, is silkworm raiser's service of increasing income.
1, male silkworm raises ratio
Male silkworm health is better than female silkworm, and when carrying out cocoon quality investigation after kind cocoon purchase, general hero pupa is slightly more than female pupa, due to hero
Moth is only intended to mate, and male moth two is handed over to quality of silkworm eggs without obvious adverse effect, often will appear remaining surplus hero in actual production
The more phenomenon of moth.Autosexing race stops male silkworm after four age male and female separations, by the certain proportion of female silkworm, and extra male silkworm is transformed into
Raw cocoon production is eliminated, and in the case where production of hybrid seeds amount is unaffected, can be supported male silkworm less, be cutd down expenses, to reach reduction
The purpose of production cost.Generally it is better than in view of middle system's kind health Japanese, is selected and remain in male silkworm ratio, middle system's kind is to friendship
Centered on the 70% of kind, Japanese kind can be centered on to hand over kind 75%.
2, isolating female from male culture technology
Female silkworm health is weaker than male silkworm, shows and becomes apparent in autosexing race, and autosexing race is adopted after male and female silkworm separates
A point feeding technology is taken, emphasis is to realize intensive culture to female silkworm, is compareed with male and female mixed breeding.Female silkworm intensive culture is first is that good mulberry is satiated with food, to female silkworm
It is preferably met the requirements from amount and matter with mulberry；Second is that stringent diseases prevention, adheres to the suitably partially close principle of the dilute feeding of female silkworm, male silkworm, adds
The selection of strong sick and weak young silkworm is eliminated and silkworm body and seat disinfection, keeps Population Health；Third is that clean Ye Yangcan, choosing is adopted without micro- spore contamination
Mulberry leaf or to mulberry leaf use blade face disinfection technology, improve silkworm egg qualification rate.Isolating female from male culture can take phase according to different condition
Measure is answered, female silkworm stays to seed station of the own mulberry field in conjunction with the area Yuan Can, after male and female separation raises inside, and male silkworm is dealt into former silkworm
Area's raising controls granulosis using the good condition in own mulberry field.The area Yuan Can seed station emphasis on isolating female from male culture is examined
Consider the micro- spore contamination of mulberry leaf and level of breeding silkworms, selects without micro- spore contamination and the horizontal high female silkworm of farmer breed of breeding silkworms.
