Mulberry tree field management, fertilising are not in place, have a strong impact on growing for mulberry tree, cause Quality of Mulberry Leaves to decline, it is impossible to meet silkworm life
Long development, requirement of the silk protein synthesis to nutrition, ultimately result in cocoon yield decline.
In production of breeding silkworms, due to Silkworm varieties resistance, sterilize not thoroughly, the food value of leaf is poor, feeding environment high temperature and humidity with
And many reasons such as pollution by pesticides, being often developed to middle and later periods outburst communicable disease in 5 age silkworms causes cocoon yield to be regretted
Receive, influence silkworm cocoon yield stability.The communicable disease of influence silkworm cocoon yield stability mainly has silkworm blood type pus illness, middle intestines
Type pus illness, desonucleosis, white muscardine, green muscardine etc..
Because silkworm is poikilotherm, environment sensitive to external world, growth cycle is short, without it is similar to higher mammal it is perfect after
Effective protective agents in its immune system, and production of breeding silkworms at present also not for above-mentioned infectiousness silkworm disease, therefore life of breeding silkworms
Above-mentioned infectiousness silkworm disease is prevented and treated in production main using putting prevention first, anti-to overweight the Comprehensive Control Strategy controlled, major measure has (1) feeding
The strong kind of resistance against diseases is supported, (2) carry out thorough disinfection, (3) before, during and after breeding silkworms to silkworm room, rearing instrument and sericulture surrounding enviroment
Strengthen managing of mulberry field, the rational application of fertilizer, improve the food value of leaf, (4) good mulberry is satiated with food, and strengthens and mascardine-proof dust or silkworm are used before silkworm constitution, (5) first feeding
The agent of body disinfection of rearing bed carries out silkworm body surface sterilization, prevents the infection of fungi, (6) remove sand in time, suitably carries green grass or young crops in batches, difference development ranks
The silkworm fed-batch of section, (7) correctly diagnose, eliminate sick silkworm, appropriate dilute foster, reinforcement silkworm body and seat sterilization, prevent silkworm rearing bed from passing in time
Dye, (8) strengthen mulberry field and control worm, prevent cross-infection, the most thermophilic needed for (9) regulation Indoor Micro, guarantee silkworm normal development
Humidity, (10) reduce high/low-temperature impact, prevent that silkworm constitution declines caused by high/low-temperature impact, (11) are prevented in silkworm agricultural chemicals
Poison.
Stable and high yields of these comprehensive preventive health measures to silk cocoon has played positive role.However, because silkworm does not have
Have in the immune system that improves of vertebrate, production also not to virosis, stiff disease resistant improved seeds, silkworm is once
The virus of Infective or fungi, in most cases silkworm is dead because of infection.Therefore, although being taken in production of breeding silkworms
Various comprehensive preventive health measures, but still often largely occur infectiousness silkworms disease in 5 middle and later periods in age, cause cocoon yield to be regretted
Receive, the stability of influence silk cocoon production, and silkworm belongs to oligophagy insect, mainly eat mulberry leaf, and on producing often because of the food value of leaf not
It is good and influence cocoon yield.Therefore breed silkworms in producing in the urgent need to the pathogenetic sericulture side of one kind increase cocoon yield prevention silkworm
