Abstract


With artificial feed sericulture sericulture in the history of an epoch-making technological innovations, has incomparable superiority of mulberry leaves infertility, our the sericulture future development direction. Artificial pellet diet recent study of the success of new silkworm artificial diet, compared with traditional cooking and feed processing modulation simple, easy storage and transport, pollution and deterioration is not easy to bait feeding silkworm is easy, can greatly improve the sericulture ergonomics easy practical advantages in the silk cocoons sterile breeding hybrids achieved the desired results. \, has made significant economic and social benefits. But both artificial pellet feed or silkworm nutrition feed, growth and development and spawning of the original silkworm has yet to carry out systematic research, thus limiting the silkworm egg production. To this end, this paper studies the The the small silkworm particles of the original species artificial diet and of 5 instar application silkworm nutrition feed on the growth and development of Cocoon cocoon, vitality, fecundity, feed efficiency, in order for the silkworm egg production applications provide a reference. Obtained the following results. 1, the original silkworm silkworm particles artificial diet sterile age and development after 1 to 2 ,35-56h, than full age mulberry leaves education control delayed fifth instar growth accelerated to narrow the gap. Pellet Artificial Diet impact through the development of the original silkworm hybrids are basically the same. Different silkworm varieties artificial diet adaptability quite different from the original species 24h sparse view Mao rate, lower than the hybrids the Japanese varieties than in the Department of varieties over the Japanese varieties setae rate 80%, can be reach the practical requirements of the production, but in the Department of varieties sparse hair low rate. 3,1 to 2 age Pellet Artificial Diet cocoon mostly improved than the full age mulberry leaves education was no significant difference in both the cocoon shell weight, cocoon shell percentage is slightly lower overall Cocoon . 4,1 to 2 age Pellet Artificial Diet impact on the rate of life because of the different varieties vary considerably, but overall, compared with mulberry leaves education cocooning rate, death rate of cage each level of pupae life was no significant differences. 5,1 ~ 2 instar Pellet Artificial Diet than full age mulberry leaves education digestibility Average increased by 7%, an average 10% reduction in the amount of dry matter per head silkworm food under 5 age, the original species cocoon weight average productivity increase of 17.2%, cocoon shell weight average productivity increase of 10.0%. 6,1 to 2 age Pellet Artificial Diet single number of moths is slightly lower than the full age of mulberry leaves education, the original species remaining egg ratio 36.1% lower on average than full age mulberry leaves education, good eggs, slightly higher than the whole age Sang Ye education, leaves egg conversion rate than full age mulberry leaves education increased by 15.7% on average.
