the impact of pgf2? on total proteins, free amino acids and the amino transferases in the gonads of silkworm, bombyx mori l. were investigated in the present experiment. the effect of pgf2? resulted in increase in the total protein and free amino acid contents in the gonads of silkworm larvae indicating improved structural and dynamic levels of organization. the enhanced activity levels of amin...

Stromatal fruiting bodies of Cordyceps cardinalis were successfully produced in cereals. Brown rice, German millet and standard millet produced the longest-length of stromata, followed by Chinese pearl barley, Indian millet, black rice and standard barley. Oatmeal produced the shortest-length of fruiting bodies. Supplementation of pupa and larva to the grains resulted in a slightly enhanced pro...

A new species of Limnophyes Eaton collected in the Corvo Branco Mountains in Santa Catarina State is described and figured, based on male and female adults, larva and pupa. The species groups with L. griseata (Edwards) and L. bidumus Sæther as the adults have a pronounced humeral pit with lanceolate setae and an additional group of lanceolate setae just posterior to antepronotum. The adults are...

The locomotory kinematics of Chironomus plumosus larvae and pupae were investigated in order to determine how different locomotory techniques may be related to (a) possible underlying patterns of muscle activation and (b) the particular lifestyles and behaviours of these juvenile stages. Larvae display three independent modes of motile activity: swimming, crawling and whole-body respiratory und...

Intra-puparial development of the females of Chrysomya albiceps (Wiedemann) (Diptera, Calliphoridae). The chronology and morphological changes that take place during intra-puparial development of Chrysomya albiceps is described based on 254 specimens reared in the laboratory. Larvae were obtained from the eggs laid by a single female. The pre-pupae were separated according to the reduction of l...

One of the most economic exploitation, widely cultivated, and financially viable non-mulberry silkworms is eri silkworm (Philosamia ricini). The feeds that consume have a significant impact on their yield silk production. A study was conducted to assess growth characteristics eco races in circumstances western region Tamil Nadu. Central Muga Eri Research Institute Jorhat, Assam provided silkwor...

In response to the successful use of monoclonal antibodies (mAbs) in the treatment of various diseases, systems for expressing recombinant mAbs using transgenic animals or plants have been widely developed. The silkworm (Bombyx mori) is a highly domesticated insect that has recently been used for the production of recombinant proteins. Because of their cost-effective breeding and relatively eas...

Silkworm has great potential as production system of recombinant mammalian proteins. When the protein products are used for medical purpose, it is required to reduce the risk of an allergy, the content of core alpha 1,3-fucosyl residue attached to the N-glycan of proteins, for example. We isolated the gene of an enzyme responsible for the transfer of core alpha 1,3-fucosyl residue, core alpha 1...

Bombyx mori macula-like virus (BmMLV) is a positive, single-stranded insect RNA virus that is closely related to plant maculaviruses. BmMLV is currently characterized as an unclassified maculavirus. BmMLV accumulates at extremely high levels in cell lines derived from the silkworm, Bombyx mori, but it does not lead to lethality and establishes persistent infections. It is unknown how this insec...
