[Method] The representative heat shock protein gene Bmhsp24.3 was screened by bioinfor- matic analysis method, and carried out real-time PCR expression analysis. [Result] The target gene Bmhsp24.3 expressed in different B. mori materials, but the expres- sion level in different materials significantly varied. The relative expression level of the gene had different degrees of changes under different rearing conditions. With the increase of rearing temperature, the gene expression was upregulated. The ma- terials with better healthiness had remarkable increase in expression of target gene, while the materials with poorer healthiness had less increase in expression of target gene. The expression difference of target gene Bmhsp24.3 was exactly consistent with the healthiness of breeds. [Conclusion] The healthiness of materials had rela- tionship with expression of target gene Bmhsp24.3. the higher the expression of tar- get gene Bmhsp24.3 was, the better the healthiness of materials was; conversely, the lower the expression of target gene Bmhsp24.3 was, the poorer the healthiness of materials was.展开更多

Its wild ecoraces like Raily, Modal, Jata, Sarihan, Laria, Bhandara and Andhra, besides domesticated Daba and Sukinda are contributing for livelihood of forest based aboriginals. However, the deforestation and extensive collection of nature grown cocoons led to declination of wild population and even have endangered few ecoraces. The government and Non Government Organizations （NGOs）, although promote ecorace conservation, it could upkeep the insect wildlife only to limited extent. But the forest department with associated self help societies has advantage in conserving tasar insect as prospective forest wealth, with better knowledge and access to its habitats. The co-ordinate efforts from forest, sericulture departments to participate native aboriginals of such societies can facilitate conserving tasar-biodiversity as most feasible forest associated resource.展开更多
