Opis:: Samples were prepared from the midgut of 4th instar larvae of the crimson speckled moth Utethesia pulchella L. to find proteolytic activity and properties. Result revealed the presence of high proteolytic activity in the midgut when taking into account specific proteinases including trypsin-like, chymotrypsin-like, elastase and two exopeptidase (aminopeptidase and carboxipeptidase). The optimal pH of general protease was 8 and 7 when using azocasein and hemoglobin as general substrates, respectively. The optimal temperature of the total proteolytic activity in the midgut of U. pulchella was 25°C and 30°C when using azocasein and hemoglobin, respectively. Proteolytic activity was inhibited significantly by soybean trypsin inhibitor (SBTI), phenylmethylsulfonyl fluoride (PMSF), trypsin inhibitor (TLCK), chymotrypsin inhibitor (TPCK) and Phenanthroline. These results provide evidences for the presence of serine proteinases as the major proteases in the midgut of U. pulchella; a key rangeland pest in warm climates. The interaction between digestive proteases and protease inhibitors have potentially important consequences for pest management programs.

Opis:: Synthetic organic compounds and those of plant origin used in insect pest control are known to affect digestive enzymes and biochemical compounds. The lesser mulberry pyralid Glyphodes pyloalis Walker is a monophagous and dangerous pest of mulberry that has been recently observed in Guilan province, northern Iran. In this study the effect of the neem formulation, Achook (0.03% azadirachtin) was studied on nutritional physiology and gut enzyme activity of the lesser mulberry pyralid G. pyloalis. The LC25, LC50, and LC90 values on 4th instar larvae were estimated as 113.6, 256.84, and 1,210.02 ppm, respectively. The neem insecticide exhibited a significant antifeedant activity when used at the highest concentration. When G. pyloalis larvae were provided with mulberry leaves treated with the neem extract, all nutritional indices, except approximate digestibility, decreased. Neem was found to affect digestive enzyme activities in the midgut of treated larvae. When larvae were fed on treated leaves, biochemical compounds in the hemolymph, such as protein, lipid, and glucose decreased but the amount of uric acid increased compared with the control.

Tytuł:: Utilization of mulberry leaves treated with seed powder cowpea, Vigna unguiculata (L) for feeding the fifth instar larvae of silkworm, Bombyx mori (L) (Race: PM x CSR2)

Opis:: The present attempt was to screen the changes in the cocoon parameters; silk filament parameters and activities of biochemical reactions catalyzed by the midgut enzymes fifth instsr larvae of silkworm fed with mulberry leaves treated with aqueous solution of seed powder of Cowpeas (Vigna unguiculata). The cowpea seed powder was dissolved in distilled water and diluted to 2.5%, 5%, 7.5%, and 10% concentrations. Fresh mulberry leaves were dipped in each concentration of aqueous solution of cowpea seed powder for half an hour. 1000 ml solution was used for 100 grams of mulberry leaves. Treated mulberry leaves were drained off completely and then used for feeding. The mulberry leaves were fed five times per day at the rate of 100 grams per 100 larvae for each time. Untreated group of larvae were feed with untreated mulberry leaves. Water treated group of larvae were feed with water treated mulberry leaves. The experimental groups of larvae were feed with feed separately with 2.5 percent cowpea treated; 5.00 percent cowpea treated; 7.5 percent cowpea treated and 10.00 percent cowpea treated mulberry leaves. Treating the mulberry leaves with various concentrations of aqueous solutions of cowpea seed powder and feeding to the fifth instar larvae of multivoltine cross breed race of silkworm, Bombyx mori (L) was found reflected into significant improvement in the weight of cocoon (31.862 Percentages); cocoon shell weight (52.336 percentages); pupal weight (26.336 percentages) and shell ratio. There was significant improvement in the silk filament length ( 00.323 percentages); silk filament weight ( 21.317 percentages) and denier scale of silk filament. Midgut enzymes (Protease, Amylase, Trehalase, Sucrase and Urease) were found influenced through treating mulberry leaves with cowpea seed powder and feeding to the fifth instar larvae of multivoltine cross breed race of silkworm, Bombyx mori (L) (Race: PM x CSR2). The contents of cowpea seeds may be associated with improvement in the growth and development through increased pattern of protein turn over and overall metabolism.

Opis:: The Leanchoiliidae is well−known from abundant material of Leanchoilia, from the Burgess Shale and Chengjiang Konservat−Lagerstätten. The first Australian member of the group is Oestokerkus megacholix gen. et sp. nov., described from the Emu Bay Shale (Cambrian Series 2, Stage 4), at Buck Quarry, Kangaroo Island, South Australia, and is intermediate in age between the well known leanchoiliid species from the Burgess Shale and Chengjiang. Phylogenetic analysis of “short great appendage” arthropods (Megacheira) in the context of the chelicerate stem group resolves the Australian species as sister to Burgess Shale, Utah, and Chengjiang Leanchoilia species, but most readily distinguished from Leanchoilia and Alalcomenaeus by a different telson shape, interpreted as being forked, widening distally, and with a few dorsally curved spines at the posterior angle. Leanchoiliid interrelationships are stable to alternative character weights, and Megacheira corresponds to a clade in most analyses.
